Standard Performance Specification for Ice Hockey Helmets
SCOPE
1.1 This performance specification2 covers performance requirements for ice hockey helmets.
1.2 The intent of this performance specification is to reduce the risk of injury to the head without compromising the form and appeal of the game.
1.3 This performance specification covers: (1) performance tests for shock absorption properties of the complete helmet and strength and elongation of the chin strap and its attachment; and (2) requirements for area of coverage and penetration.
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.5 The following precautionary caveat pertains only to the test methods portion, Section 12, of this performance specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Performance Specification for
Ice Hockey Helmets
This standard is issued under the fixed designation F1045; the number immediately following the designation indicates the year of

INTRODUCTION
Ice hockey is a contact sport with intrinsic hazards. The use of protective equipment will not
eliminateallinjuriesbutshouldsubstantiallyreducetheseverityandfrequencyofinjury.Participation
in the sport of ice hockey by a player implies acceptance of some risk of injury. The goal is to
minimize this risk.
Thisperformancespecificationforheadprotectiveequipmenthasbeenpreparedafterconsideration
of head protection relative to the following principle risks: high-mass, low-velocity impact (various
playing situations), and fit. This performance specification may be modified as other risks are
identified.
Performance requirements were determined after consideration of state-of-the-art of helmet design
and manufacture and the demands of the sport.

point (impact point) of the elevated helmet and the apex of the
impact surface.

headform during impact to the acceleration due to gravity.

curing attachments to the shell shall be so attached that the
degree of protection afforded the wearer by the protective
padding or cushioning material of the helmet is not thereby
