Throughout this Rulebook, a number of references are made
for particular products to meet certain specifications (i.e. SFI
Specs, Snell, DOT, etc.). It is important to realize these
products are manufactured to meet certain specifications,
and upon completion, the manufacturer labels the product as
meeting that spec. Therefore, except as outlined under SFI
requirements, any change to the product voids certification.
Under no circumstances may any certified product be
modified, altered, or in any way vary from the “as
manufactured” condition. Such a practice is in violation of
9
the SFI, Snell, DOT, etc. program, voids such certification
and therefore will not be accepted by USHRA .

approved and is correctly installed, worn, maintained and
used.
