ASTM E3347/E3347M : 22

1.1 This standard specifies minimum performance requirements and test methods for the ballistic resistance of shields used by U.S. law enforcement officers to protect against handgun and rifle ammunition.

1.2 Products addressed by this specification include hand-held or hand-carried shields (having single or multiple panels, multi-fold shields) and person-portable shields with wheels.

1.3 Products not addressed by this specification include fixed or mobile barriers not intended to move during an operation and flexible shields that drape across the surfaces upon which they are placed (for example, ballistic blankets).

1.4 This specification addresses ballistic performance in terms of resistance to penetration (RTP) of the shield body, body edges, viewports, fasteners, and weak points.

1.5 Shields covered by this specification are classified into ASTM shield ballistic protection levels (see Section 10).

1.6 This specification is applicable for certification testing, verification testing, or research and development testing.

1.7 Values stated in either the International System of Units (metric) or U.S. Customary units [inch-pound] are to be regarded separately as standard. The values stated in each system may not be exact equivalents. Both units are referenced to facilitate acquisition of materials internationally and minimize fabrication costs. Tests conducted using either system maintain repeatability and reproducibility of the test method and results are comparable.

1.8 This specification is divided into the following sections:

1.9 The tests required by this standard have inherent hazards. 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.

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