I.
PURPOSE
The purpose of this manual is to prescribe procedures for the operation of the Eurovent Certified
Performance Programme for Air Handling Units, in accordance with the Eurovent Certified
Performance Certification Manual.
II.
SCOPE
This programme applies to selected ranges of Air Handling Units. Each range shall at least present
one size with a rated air volume flow below 7 m 3/s. All Real Unit sizes in the range up to the
maximum stated air flow shall be declared. All Model Box configurations shall be declared.
Ranges without at least one size with a rated air volume flow below 7 m 3/s (25 000 m3/h) are
excluded.
III. BASIC OUTLINE OF THE PROGRAMME
III.1 Preapplication
Before the licence agreement is signed between the company and Eurovent Certita
Certification, the preapplication procedure shall be completed.
The company shall first submit to Eurovent Certita Certification name of the range and
complete list of names and versions of the corresponding selection tools (selection softwares)
for verification by an auditor appointed by Eurovent Certita Certification. If the software fulfils
all preliminary requirements, the company shall submit to Eurovent Certita Certification the
complete list of factories where the range is produced for verification by an auditor appointed
by Eurovent Certita Certification. If the software and the factory fulfil all the preliminary
requirements, the company is entitled to sign the Licence Agreement.
III.2 Qualifying procedure
After signing the Licence Agreement, the Applicant shall submit to Eurovent Certita
Certification the declaration list with all Real Unit (RU) sizes and Model Box (MB)
configurations with all the required characteristics and performance data as required by the
Rating Standard, RS 6/C/005.
The following number of units per factory producing the range (except the case of “sister
factories”, see IV.10) are then required for test in an independent laboratory selected by
Eurovent Certita Certification:
 The minimum number of Model Boxes to cover all worst configurations of the
mechanical, thermal and acoustical performance. If several ranges use the same
construction, the corresponding unit will be tested only once.
 One complete Air Handing Unit, being one size from the range, for all performance. The
Real Unit is selected during the factory visit by the auditor appointed by Eurovent Certita
Certification.
For units above the stated air flow rate of 7 m3/s, the software shall be checked for
consistency. If the tests show conformity with the relevant Rating Standard and consistency is
verified, certification is granted until next annual on-site checking of software.
III.3 Repetition procedure
For mechanical, thermal and acoustical testing, Model Boxes shall be tested every six years
for ISO-certified factories, every three years otherwise. For performance testing, a Real Unit
from recent regular production shall be tested, every three years for ISO-certified factories,
AHU, OM-5-2014
Page 5 of 36
every year otherwise. If several factories produce exactly the same range with the same
components, suppliers and methods, one unit is sufficient instead of one per factory. In
addition, annual onsite checking of software shall be carried out every year. When the
repetition procedure is passed certification is renewed for another campaign.
III.4 Failure treatment
When a unit fails to comply with the requirements of the relevant Rating Standard, failure
treatment shall be applied.
IV. OPERATION OF THE PROGRAMME
IV.1 Declaration of data
Each manufacturer shall nominate one contact person who will deal with all certification
matters, plus eventually one by factory.
a.
Rated performance data
All characteristics shall be expressed in SI Units.
b. Certification forms
Submittal of certification of models shall be completed and sent to Eurovent Certita
Certification as .xlsx files. Copies of these forms are part of this manual (see APPENDIX
D).
Original Equipment Manufacturer (OEM): Form AHU-1A for Real Units and Form AHU-1B
for Model Boxes will be used.
Brand Name: For models submitted by a company presenting on the market units, under
its own brand, manufactured by a certified company, forms AHU-2A and AHU-2B will be
used to identify the corresponding model number of the OEM.
Technical forms: For models selected for test, Forms AHU-3A and AHU-3B have to be
completed with technical description of all components along with characteristics and
performance data.
Evaluation of test result: For models tested, Forms AHU-4A is added to the test report
and AHU-4B is sent by Eurovent Certita Certification, showing the deviations between
claimed and measured data.
c.
Modifications to the range
The Participant shall inform Eurovent Certita Certification and the auditor of any
modification to the range and/or software, using Form AHU-5. A new software version
without impact on performance does not have to be sent. If new components (fans, coils
etc) are implemented in standard production, manufacturer shall inform Eurovent Certita
Certification and provide new software to the auditor. For next test new components shall
be selected.
Non compliance is considered as a non-respect of procedures (see IV.14).
Anytime, Eurovent Certita Certification has the right to perform extra checking of
software. Eurovent Certita Certification decides whether the modification is significant for
the certified performance data or not. In the case of significant modifications Eurovent
Certita Certification is entitled to demand adequate tests to verify the influence on
performance data. This test shall not be considered as a repetition one.
AHU, OM-5-2014
Page 6 of 36
IV.2 Preapplication procedure
During the preapplication procedure, the auditor appointed by Eurovent Certita Certification
shall first verify that the software fulfils minimum requirements (no certification shall be
accepted without appropriate selection software). If yes, he shall visit the factory, verify that
AHUs are really manufactured there and selected with the software, and send a report of his
visit to Eurovent Certita Certification. If the report shows that rules are not followed the Licence
Agreement shall not be signed.
IV.3 Software
An English version of the software selection is necessary. Each quotation of a certified AHU
shall include the date/code/number of the software version used for the selection of the unit.
From the version code-key it shall be possible to check what the latest technical software
version is by splitting up the code in more characters. An example of a suitable code is given
below:
Version: XY / Z
characters indicating a version serial number,
not affecting the selection results
characters to indicate the technical version serial number
The participant is obliged to send the most recent technical software version to Eurovent
Certita Certification.
The selection software shall be operative as an entity with all unit components integrated in
one software. Components in an AHU that are selected with different software or any other
means of selection cannot be certified. The units of the applied range shall be built with
components specified in the selection software. If some components not present in the
certified software performing a certified performance item (see VI.2 of Rating Standard) are
included in the technical specification of a particular order, the following statement shall be
provided in the quotation: “This component is not included in the software Eurovent certified”.
This statement is not required for components serving for non-certified performance items (see
list on VI.2 of RS 6/C/005).
At least four sections must be included: fan, filter, heating and cooling. When a heat recovery
section is available, it shall be declared and included in the selected unit for test for
certification.
Consistency of the software shall be verified by the auditor appointed by Eurovent Certita
Certification. In case inconsistency of the software is observed, failure treatment shall be
applied.
Anytime, Eurovent Certita Certification has the right to collect data directly from customer and
perform extra checking of software.
IV.4 Factory visits
Before each visit the auditor appointed by Eurovent Certita Certification shall collect and study
the construction details and claimed performance of the relevant AHU range in order to make
a proper selection of suitable unit(s) for testing.
Anytime, Eurovent Certita Certification has the right to ask an auditor to conduct a surprise
visit to participants’ factory as well as to collect data directly from customer and perform extra
checking of software.
During selection visits, a factory tour shall be made by the auditor, accompanied by
manufacturer’s technical expert. A random selection of at least one unit under construction or
just built, shall be made. The selected unit shall be suitable for testing. If no unit suitable for
AHU, OM-5-2014
Page 7 of 36
testing is under construction or just built, a random selection from files of recently delivered
units shall be made.
The entire composition and technical specifications of the selected units shall then be checked
onsite. Manufacturer’s technical expert shall fully inform the auditor by submitting all relevant
assembly drawings, specifications and technical data sheets of the selected units. Agreement
shall be reached between manufacturer and the auditor on final selection of Real Unit for
testing.
During annual on-site checking of software, the same procedure shall be applied, without
selection of unit for testing so without the restrictions for measuring facilities. This implies that
any size may be selected.
The expected performance shall be recalculated based on components reselected with the
software provided to Eurovent Certita Certification. The composition and technical
specifications and performance from recalculation shall be the same as the one specified and
announced to the customer. If in the meantime the Participant has officially launched a new
software version and recalculation is made with this version, deviations should be traceable in
the software update record sheet (see D.IV.2). Deviations on performance above tolerances
can lead to additional test (see IV.1c). If it appears that different software had been used, this
shall be considered as a non-respect of procedures (see Certification Manual).
In addition, mechanical construction (all the parameters) of one production unit shall be
verified by the auditor, to compare certified characteristics of production with the tested Model
Box(es). If it appears that different construction had been used, additional Model Box test shall
be required by the auditor.
Finally, consistency of heat recovery shall be verified by the auditor. At least one unit shall be
verified with the methodology detailed in the following paragraph.
In case of force majeure (e.g. accidents, labour disputes, natural events, acts of war) which
would not allow Eurovent Certita Certification to perform a factory visit Eurovent Certita
Certification can decide to replace it by another mean of verification, to postpone it within a
reasonable deadline or to cancel it. The Compliance Committee will be made informed
regarding these cases.
IV.5
Consistency check of heat recovery
a.
Manufacturer uses Eurovent certified heat recovery systems (HRS)
Compare the efficiency and pressure drop data in the AHU quotation or software with
results obtained from the current stand-alone certified software from the HRS supplier.
AHU manufacturer can never claim higher efficiencies and/or lower pressure drops than
the values received from the stand-alone software.
If possible one quotation with a rotor and one quotation with a plate heat exchangers
have to be checked.
b. Manufacturer does not use Eurovent certified HRS
Additional testing of non-certified HRS are requested in the laboratory of the regular
certification campaign, of the different models, one every year. Repetition would only be
necessary in case of change of the structure of the HRS. When a HRS is tested in the
RU one year, this additional testing is not necessary for that year.
Compare the efficiency and pressure drop data in the AHU quotation or software with
results obtained from the test result. Deviation shall be equal or lower than the
acceptable tolerance defined in the certification programme for the HRS. In case a RU is
tested every year, this additional testing is not necessary.
AHU, OM-5-2014
Page 8 of 36
c.
For certified and non-certified rotors
Observations of rotor arrangements in the AHUs shall be made during the annual factory
inspection. If it appears that (sometimes) parts of the actual heat exchanger surface of
the rotor are blanked / obstructed it shall be verified in manufacturer’s software if this
unfavourable assembly has been considered. The software shall predict (small) reduction
in efficiency and (substantial) pressure drop increase, compared to a selection with
completely open rotor surface.
IV.6 Qualifying campaign
For a company (“Brand name”) presenting on the market units, under its own brand,
manufactured by a certified company, only on-site checking of software shall be conducted at
the place (“office”) where the orders to the customers can be accessed. This place is often the
factory of the certified manufacturer.
For manufacturers, Real Units taken from the production line shall be selected by the auditor
appointed by Eurovent Certita Certification during a factory visit, using the selection software.
Models Boxes will be directly selected by Eurovent Certita Certification from the declaration
list, to cover all worst configurations of the mechanical, thermal and acoustical performance
(see Table 1).
Selected units shall be sent to the independent laboratory within maximum 6 months. If this
deadline is not fulfilled another on-site checking with selection shall be scheduled within
maximum one year from the previous on-site checking.
Units are then tested and the obtained performances compared with the values calculated
using the software. The test on the Real Unit of a range can be carried out after the test results
on the Model Box(es) is/are available.
Assembly places of flat-package units shall be considered exactly the same way as
manufacturing places. When a manufacturer presents several manufacturing places, each
place shall be considered independently.
If all the test results are within the tolerances and calculation model appears consistent,
Eurovent Certita Certification shall grant the certification. If not, failure treatment shall be
applied.
When certified, the range is published on the Eurovent Certified Performance website with an
agreement number, associated characteristics and performance, name and version of the last
software verified by Eurovent Certita Certification, and production places. The participant is
then entitled to use the certification mark for this range in literature and on products (see V.2).
It shall be obvious for which products the certification is granted (see also APPENDIX B and
Certification Manual).
IV.7 Repetition campaign
For a company (“Brand name”) presenting on the market units, under its own brand,
manufactured by a certified company, only on-site checking of software shall be conducted
annually at the place (“office”) where the orders to the customers can be accessed.
For manufacturers, Participant’s quality control shall be appropriate to maintain the
performance within the tolerances. A quality system according to ISO 9001 (covering the
production quality systems) is acknowledged by a reduction in the frequency of repetition tests.
The manufacturer shall then annually provide a valid ISO 9001 certificate to Eurovent Certita
Certification. In addition, annual on-site checking shall be performed in each Participant’s
factory(ies). Assembly places of flat-package units shall be considered exactly the same way
as manufacturing places.
AHU, OM-5-2014
Page 9 of 36
For each certified range and factory, repetition tests in the independent laboratory selected by
Eurovent Certita Certification shall be required:
 Every six years for mechanical, thermal and acoustical performance on Model Boxes for
participants holding valid ISO 9001 (every three years otherwise)
 Every three years for performance on Real Unit for participants holding valid ISO 9001
(every year otherwise)
Eurovent Certita Certification shall select the units for repetition using the same procedure as
for selection of units for the qualification test. If possible, a RU size or MB configuration
different from those previously tested shall be selected.
If all the test results are within the tolerances and calculation model appears consistent,
Eurovent Certita Certification shall maintain the certification for another period. If not, failure
treatment shall be applied.
IV.8 Ranges to be taken out of production
Running a test on a unit from a range which is going to disappear from the market can
represent a useless cost for the Participants. If a test is necessary on a unit from a range
which is going to disappear from the market, the Participant may send an official letter to
Eurovent Certita Certification stating that the range will disappear between the date of the
scheduled test and the date + one year. The range remains then certified for maximum one
year. If the Participant changes his mind or if it appears that the range is still available after
that time, it is considered as a major breach of the rules, and the Participant will have to pay a
penalty fee of 15 000 €. In addition, the unit will have to be tested and the following test will
have to follow normal schedule.

Regarding Model Boxes, Eurovent Certita Certification shall select the minimum number of
units to cover the construction variations available on the software and catalogue under the
declared range names. All variations (marked by a X) and worst cases are mandatory to be
tested according to the Table 1 above, and worst case performances can be transferred from
the tested MB to other constructions. To claim better class on one performance data, another
MB with the construction parameter variation has to be tested too.
AHU, OM-5-2014
Page 10 of 36
Selection of one Real Unit suitable for testing shall be made during selection visits as
described above (see IV.4). Size of the units, air volume performance, heating and cooling
capacity, shall be within the limits of the measuring facilities of the laboratory. An up-scaled or
down-scaled unit can be selected if no suitable size is available. In case no unit with heat
recovery or cooling/heating coils can be provided by the factory, these components and the
associated performance shall be non-certified. Because it is a significant parameter for the
energy efficiency classification, in case the software proposes heat recovery, then the selected
unit shall include heat recovery.
Unit for test shall be supplied to the laboratory within six weeks for factories in Europe and
within eight weeks for factories outside Europe (see APPENDIX C). When the manufacturer
does not meet the time limits for the supply of units this will be considered as a non-respect of
procedures. The manufacturer shall inform the laboratory (preferably before the test) if he
wants the unit to be scrapped after the test results are available.
IV.10 Ranges produced in several production places
When a manufacturer presents several production places, each place will be considered
independently so each factory has to be visited every year by the auditor appointed by
Eurovent Certita Certification (selection or annual on-site checking). Assembly places of flatpackage units shall be considered exactly the same way as manufacturing places.
Regarding the selection of units to be tested, the production places for an identical product –
identical software, identical components (designation) and suppliers, same casing (same
drawings and materials), same assembly procedures and ISO 9001 – have to be considered
as one collective production place. In that case each time a different production location will be
randomly chosen for the selection of the unit to be tested. The different production places are
thus called “sister production places”.
During the annual on-site checking (see IV.4), if there is any suspicion that the production
place cannot ensure the same performances as its sister production places, then the auditor
may ask that a Real Unit and/or Model Box be tested.
IV.11 Procedures at the laboratory
a.
General
Only the independent laboratory personnel shall be permitted to handle test units. The
manufacturer's installation and handling instructions shall be followed. The laboratory
shall be responsible for uncrating, handling, testing and recrating the unit for shipment.
The laboratory personnel shall make repairs to the test unit only in agreement with the
manufacturer. No manufacturer's personnel shall be present in the test facility during the
test.
b. Test conditions
The units shall be tested at the conditions as stated in the relevant Rating Standard.
Thermal tests will be performed at 2 conditions in the heating mode and 2 conditions in
the cooling mode (one condition at manufacturer’s rated design and one condition
selected by Eurovent Certita Certification within the scope of the selection software).
Independent laboratory shall test units at the conditions as close as possible to the
selected rating conditions.
Aerodynamic tests (air flow - pressure - power input) shall be performed in accordance
with the test standard ISO 5801, in an operating range of +/-5% around the selected
rating point.
AHU, OM-5-2014
Page 11 of 36
Testing for heat recovery shall be carried out with at least 20 K difference, under dry
conditions (supply air temperature should not be below +5°C).
c.
Test report and tests results
For each unit, upon completion of all the measurements, the laboratory will render a test
report (pdf) to Eurovent Certita Certification with tested data compared to original
selection data. If at least one performance measurement is out of the tolerances, the
auditor shall conduct a “test check”, i.e. the selection software will be used to recalculate
the performance at conditions used for test: test data will be compared to recalculation
data. Eurovent Certita Certification will transmit a copy of the report together with results
of test check (Forms AHU-4, see APPENDIX D).
Manufacturer has to collect its products one month after receiving the test report. After
this delay, the laboratory will destroy the units if not collected and the manufacturer will
be invoiced through Eurovent Certita Certification.
If the results are out of the allowable tolerance, or the calculation model appears
inconsistent, failure treatment shall be applied.
IV.12 Failure treatment
For each test, a performance item fails when the difference between the declared value and
the measurement differs by more than the allowable tolerance (see relevant Rating Standard).
A test fails when one or more performance(s) fail. In case of failure, Eurovent Certita
Certification shall promptly notify the Participant.
a.
Component failure
The manufacturer shall be authorised to examine the reasons of the failure. In case of a
component failure the unit may be repaired or replaced by a new one of the same model
within 4 weeks, which shall be tested then, according to normal schedule of the
laboratory.
b. Unit failure on a real unit
If the failure is established after the recalculation, the manufacturer shall rerate his data
by adapting the software to the test results within 6 weeks (see APPENDIX C). If the
software is then in accordance with all measurements, certification is granted or
maintained with the re-rated data.
After reverification (“test recheck”), if the software is still not in accordance with the test
results, manufacturer will have two additional weeks for final adjustment of the software
(see APPENDIX C). In case of new failure, no adjustment of software will be accepted
and manufacturer has to restart the test procedure.
c.
No class reached during RU tests
In case of failure on RU tests not reaching any Filter By-pass Leakage (FBL) class, it is
considered as Component failure (immediate stop of the test) and complete retest is
mandatory. In case retest is failed, manufacturer is excluded from the programme for 1
year.
In case of failure on RU tests not reaching any Casing Air Leakage (CAL) class, it is
considered as Component failure (immediate stop of the test) and complete retest is
mandatory. In case retest is failed, manufacturer is excluded from the programme for 1
year.

d. Unit failure on a Model Box
Manufacturer has four weeks after notification of failure to select one of the following
alternatives:
 Accept measured values. (Uprate is allowed.)
 Ask for a second test on the same unit. In this case, the Manufacturer can choose
to re-test only the performances which are not accepted
 Ask for a second test on another unit of the same model selected by Eurovent
Certita Certification. The delivery shall be done within 8 weeks from the date of
the test report. In this case, all measurements are to be re-tested.
e.
Failure in case of multiple production places
When a range is tested for different production places, if one repetition test fails, all
production places will have to re-rate their data and the software shall be re-rated
according to the worst test results for each performance item.
f.
Irregularities in production places
Irregularities found in a factory can be a reason for retesting or suspension of certification
of the factory or the complete range. In case several factories produce the same range, if
one factory is suspended, the Participant has one year to align it. After this delay, if the
factory is still not in accordance with the requirements, the complete range is suspended
from certification for one year.
IV.13 Special complaint procedure
The general complaint procedure is described in Certification Manual.
In addition, if a Participant obtains doubtful data from a competitor quotation he may present a
complaint request. The Participant who complains will pay 1000 € as fee. Eurovent Certita
Certification auditor will examine complaint within 6 weeks and complaint data will be also
used during annual on-site checking.
If checking results show that the obtained data are different – meaning that other software had
been used or quotation data manipulated – this is considered as a non-respect of procedures
(see Certification Manual). The 1000 € fee will then be sent back to the plaintiff and it will be
invoiced to the Participant who failed.
IV.14 Brand Name
This covers the case of models submitted by a company presenting on the market units, under
its own brand, manufactured by a certified company. When Company A doesn’t produce his
own range but distributes under its own brand ranges already certified by Participant B, no
additional test is required for A. Nevertheless, A has to declare to Eurovent Certita Certification
a place (“office”) where the orders to the customers can be accessed to and the software can
be annually verified by an Eurovent Certita Certification auditor, during the same quarter as the
verification of software hold by B. A’s office is often B’s factory. If a range or a production place
of B doesn’t fulfil the requirements and B’s certificate is suspended and/or expelled from the
programme, A is also automatically suspended. If B quits certification, A is offered the
possibility to cover test expenses for B’s products.
The Brand of the A company must be shown on the output.
A is fully responsible of his software and any non compliance may have a consequence on A
certification, even if B is the software provider.
AHU, OM-5-2014

IV.15 Non-respect of procedures
The general consequences of non-respect of procedures are described in Certification Manual.
In complement applied penalties can be:
 A certified range and/or production place is withdrawn from the Eurovent Certified
Performance website for one year.
 Any minor non-conformity identified during an on-site checking will be escalated to major
if not solved prior or during the next follow-up audit.
 At the end of the first penalty year and after a second checking, if failure occurs again,
the certified range and/or production place is withdrawn from the Eurovent Certified
Performance website for three years.
The level of penalties and the list of major and minor non-conformities are listed in 0.

APPENDIX E.
MAJOR / MINOR NON COMPLIANCES
Each certified range shall be allocated of 15 audit points (after first delivery of certificate). Each major
non-compliance related to the range (independently of the manufacturing place), shall remove 2
points to the account of the range.
If a range reaches 0 point, Participant shall be notified for immediate suspension of the range for one
year. A 24-months period without major non-conformity resets the account to the initial level.

Mis-use of ECC mark in portraying products / ranges to be certified when they are not, this also applies to branded products that have not been declared to ECC or tracability of the
original ECC manufacturer has been removed, either software or unit (IV.14 - OM-5)
Use of ECC mark: The participant is entitled to use the certification mark for the certified range in literature and on products, however it must be obvious for which products the
certification is granted. See also guidance in Certification Manual.

If it appears that different MB construction has been used during the factory audit to that supplied for the MB certification charateristics, then this is deemed a failure and additional
MB test shall be required.
Several production places: During the annual on-site checking (see IV.4), if there is any suspicion that the production place cannot ensure the same performances as its 'sister'
production places, then the auditor can issue a major non-compliances and ask for that a Real Unit and/or Model Box be tested.

Consistancy checks of Heat Recovery stand-alone ECC software or Real Unit component test to unit selection: NO unit selection software performance can be higher than that of the
stand-alone ECC software or outside the tolerance of the independent Heat Recovery test report.
Able to re-calculate the last Real Unit before removing the compoment from selection software, otherwise re-calculation can not be completed.
If moving to new software platform between the period when the Real Unit was selected & re-calculation, the same unit (all components) must be selectable.
During the factory audit if it appears that different software has been used, then this shall be considered as a non-respect of procedures (see certification manual)
Calculated Eurovent Certified Performance energy class is lower than the claimed energy class
If it is not allowed to display the energy class classification a statement shall be written e.g "Heat Recovery component -and/or fan selection beyond certified software do not comply
