ASTM F1446-05

Standard Test Methods for Equipment and Procedures Used in Evaluating the Performance Characteristics of Protective Headgear

SCOPE
1.1 These test methods describe laboratory equipment, procedures, and basic requirements pertinent to testing protective headgear. Deviations or additions, or both, to these test methods will be specified, as required, in individual performance standard specifications.
1.2 Requirements—The protective headgear is to be tested under specified environmental conditions for the following:
1.2.1 Impact attenuation (the limiting of head acceleration) of the protective headgear.
1.2.2 Strength of the retention system and its attachment.
1.2.3 Special tests for particular protective headgear uses will be specified in the individual standard specifications to be used in conjunction with these test methods.
1.3 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.

Performance Characteristics of Protective Headgear
This standard is issued under the fixed designation F 1446; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
These test methods specify equipment and procedures used for testing protective headgear.
Individual ASTM performance standards (standard specifications) will use these procedures and
equipment. Test conditions, pass-fail criteria, and other performance requirements will be specified in
the individual performance standards, tailored to the needs of a particular activity (for example,
bicycling, skateboarding, skiing, etc.).
These test methods were developed using resources in medical, scientific, mechanical engineering,
human factors, and biomechanical fields. However, it is recognized that it is not possible to write a
protective headgear performance standard that will result in headgear that can protect against injury
or death in all accidents. It is also recognized that serious injury or death can result from both low-
and high-energy impacts, even when protective headgear is worn.
These test methods incorporate aspects of other recognized headgear performance standards. They
draw from work done by others where appropriate for these test methods. These standards are
referenced within this standard test method. It should be noted that these test methods specify
laboratory tests of completed headgear to measure its ability to reduce head acceleration during use
and other selected parameters.
