    Significance and Use

    4.1 The purpose of this standard is to provide reliable and repeatable compression test methods for the evaluation of helmets used in law enforcement, corrections, and military applications.

    4.2 It is anticipated that this standard will be referenced by certifiers, purchasers, or other users in order to meet their specific needs. Those users will specify which test methods apply and will specify any performance categories or levels.

    1. Scope

    1.1 This standard provides test methods for assessing compression resistance of helmets worn by military, law enforcement, and corrections personnel. These test methods are applicable for many styles of helmet (that is, high-cut, mid-cut, full-cut).

    1.2 Three compression test methods are included: (1) top-to-bottom, (2) side-to-side, and (3) front-to-back.

    1.3 It is anticipated that this standard will be referenced by suppliers, certifiers, purchasers, or other users to meet their specific needs. Those users will specify, in other standards and specifications, which test methods and conditioning procedures are applicable and will specify any performance categories or levels.

    1.4 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

    1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
