ASTM E3343/E3343M-22

4.1?The purpose of these test methods is to provide reliable and repeatable nonballistic test methods and conditioning procedures for the evaluation of head protection used in law enforcement and corrections applications.

4.2?It is anticipated that these test methods will be referenced by certifiers, purchasers, or other users in order to meet their specific needs. Those users will specify which test methods and conditioning procedures are applicable, and will specify any performance categories or levels.

4.3?These test methods include some procedures and references to other standards to ensure that relevant properties are addressed.

1.1?This standard provides nonballistic test methods and conditioning procedures for assessing head protection (that is, helmet and face shield) worn by law enforcement and corrections officers.

1.2?These test methods do not address eye protection other than face shields that are attached to the helmet.

1.3?It is anticipated that these test methods 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?In these test methods, other standards and specifications and unless specified elsewhere refer to documents (for example, military standards, purchase specifications) that require the use of these test methods. Purchasers and other users are responsible for the other standards and specifications and for specifying any requirements that supersede those of these test methods.

1.5?UnitsThe 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.

1.6?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.

1.7?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.
