1.1 This specification specifies requirements for ballistic-resistant panels to be mounted in or on public safety vehicle doors to protect against complete penetration of projectiles from small arms.21.2 The purpose of this specification is to define minimum performance for ballistic-resistant vehicle door panels.1.2.1 In addition to the required tests, optional tests with specific conditions are provided that allow testing beyond the minimum requirements of this specification. Statements of conformance with this specification do not include any optional test unless the optional test is conducted, and the results are included in the test report.1.3 This specification requires ballistic testing of vehicle door panels mounted either in a test fixture or mounted on a vehicle door for which the panel is designed.1.3.1 Door panels intended to be mounted inside a vehicle door shall be assessed in a test fixture with air backing.1.3.1.1 Two optional ballistic tests are provided for vehicle door panels intended to be mounted inside a vehicle door:(1) The preferred optional ballistic test assesses the panel in a vehicle door for which the panel is designed.(2) If a vehicle door for which the panel is designed is not available, a second optional ballistic test assesses the panel in a test fixture with air backing and a door skin simulant in front of the strike face of the panel.1.3.2 Door panels intended to be mounted on the exterior of a vehicle door shall be assessed on a vehicle door for which the panel is designed.1.3.3 An optional extreme temperature ballistic test is provided for purchasers concerned with performance of vehicle door panels in very hot or very cold environments.1.3.4 The optional ballistic tests are provided in Appendix X1.1.4 Selection and procurement guidance is provided in Appendix X2 to assist purchasers in using this specification to procure vehicles with ballistic-resistant door panels or to retrofit existing vehicles with ballistic-resistant door panels.1.5 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to non-SI units that are provided for information only.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.

This specification prescribes requirements for demonstrating that a building's location provides a minimal level of access to public transit that allows occupants to travel to places of employment and to run typical errands. It is intended to facilitate the decision-making process for selection of a building site that provides opportunities for occupants to use public transit. It specifies a single indicator regarding the environmental performance related to a building's location, and for evaluating whether a building is located in such a way as to minimize the impacts associated with occupants' travel.1.1 This specification provides requirements for demonstrating that a building’s location provides a minimal level of access to public transit such that building occupants can rely on public transit to travel to places of employment and to run typical errands.1.2 This specification addresses a single indicator regarding the environmental performance related to a building’s location. It provides one option for evaluating whether a building is located in such a way as to minimize the impacts associated with occupants’ travel.NOTE 1: The indicator in and of itself is insufficient to imply any level of “sustainability” for the building or the neighborhood. Similarly, a building’s failure to meet this specification does not necessarily signify a lack of sustainability. Other indicators may be more appropriate for that building or region; those indicators are outside the scope of this specification.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 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.1.5 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.

1.1 This specification addresses less lethal chemical irritant sprays used by law enforcement, corrections, and other public safety officers.1.2 This specification is limited to duty belt-mounted canisters.1.3 This specification is limited to sprays intended for use on humans.1.4 This specification defines requirements for products containing liquid aerosol Oleoresin Capsicum (OC) spray (that is, pepper spray), Orthochlorobenzalmalononitrile (CS) spray (that is, 2–chlorobenzylidenemalononitrile; CAS #: 2698-41-1), or OC-CS combination spray. The formulation may be delivered as a stream, gel, foam, cone, or vapor.1.5 This specification does not address incendiary devices or “hot gas.”1.6 Products covered by this specification may be flammable or nonflammable.1.7 Products covered by this specification are hazardous substances as defined by 16 CFR 1500.3.1.8 It is intended that the following related practice be used in conjunction with this specification: Practice E3215.1.9 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.1.9.1 For some quantities in Sections 9, 10, and 11, only SI units are used to be consistent with industry practice.1.10 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.1.11 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.
