5.1 Use this test method to measure the thermal protection provided by different materials, garments, clothing ensembles, and systems when exposed to a specified fire (see 3.2.2, 3.2.3, 4.1, and 10.4).5.1.1 This test method does not simulate high radiant exposures, for example, those found in electric arc flash exposures, some types of fire exposures where liquid or solid fuels are involved, nor exposure to nuclear explosions.5.2 This test method provides a measurement of garment and clothing ensemble performance on a stationary upright manikin of specified dimensions. This test method is used to provide predicted skin burn injury for a specific garment or protective clothing ensemble when exposed to a laboratory simulation of a fire. It does not establish a pass/fail for material performance.5.2.1 This test method is not intended to be a quality assurance test. The results do not constitute a material’s performance specification.5.2.2 The effects of body position and movement are not addressed in this test method.5.3 The measurement of the thermal protection provided by clothing is complex and dependent on the apparatus and techniques used. It is not practical in a test method of this scope to establish details sufficient to cover all contingencies. Departures from the instructions in this test method have the potential to lead to significantly different test results. Technical knowledge concerning the theory of heat transfer and testing practices is needed to evaluate if, and which departures from the instructions given in this test method are significant. Standardization of the test method reduces, but does not eliminate, the need for such technical knowledge. Report any departures along with the results.1.1 This test method is used to provide predicted human skin burn injury for single-layer garments or protective clothing ensembles mounted on a stationary upright instrumented manikin which are then exposed in a laboratory to a simulated fire environment having controlled heat flux, flame distribution, and duration. The average exposure heat flux is 84 kW/m2 (2 cal/s·cm2), with durations up to 20 s.1.2 The visual and physical changes to the single-layer garment or protective clothing ensemble are recorded to aid in understanding the overall performance of the garment or protective clothing ensemble and how the predicted human skin burn injury results can be interpreted.1.3 The skin burn injury prediction is based on a limited number of experiments where the forearms of human subjects were exposed to elevated thermal conditions. This forearm information for skin burn injury is applied uniformly to the entire body of the manikin, except the hands and feet. The hands and feet are not included in the skin burn injury prediction.1.4 The measurements obtained and observations noted can only apply to the particular garment(s) or ensemble(s) tested using the specified heat flux, flame distribution, and duration.1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.6 This method is not a fire test response test method.1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units or other units commonly used for thermal testing. If appropriate, round the non-SI units for convenience.1.8 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.1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.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 Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 U.S. Department of Defense and U.S. Department of Justice standards and specifications require assessing the penetration resistance and backface deformation of ballistic-resistant body armor.5.2 This test method may be used by private-sector and government laboratories, manufacturers, research and development organizations, and others assessing the ballistic resistance of body armor or performing research and development of new materials.5.3 It is intended that this test method be referenced by other standards, specifications, or test methods.1.1 This test method addresses resistance to ballistic penetration and to backface deformation (BFD) for ballistic-resistant torso body armor and shoot packs.1.2 This test method is intended for testing of soft body armor, hard armor plates, in conjunction with armor, and shoot packs mounted on a clay block as the backing assembly.NOTE 1: This test method does not apply to ballistic helmets, inserts, trauma packs, trauma plates, or accessories.1.3 The test method does not specify performance criteria or usage of the test results.1.4 This test method does not address conditioning of test items.1.5 It is anticipated that this test method will be referenced by certifiers, purchasers, or other users in order to meet their specific needs.1.5.1 Purchasers and other users will specify the ballistic test threats to be used. Within this test method, the reference defining the ballistic test threats is called the “test threats document.”1.5.2 In this test method, “other standards and specifications” and “unless specified elsewhere” refer to documents (for example, military standards, purchase specifications) that require the use of this test method. Purchasers and other users are responsible for the “other standards and specifications” and for specifying any requirements that supersede those of this test method.1.6 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.1.6.1 The user of this standard will identify the system of units to be used, and it is critical to ensure that any cross-referenced standards maintain consistency of units between standards.1.7 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.1.8 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.

5.1 This standard is intended to provide guidance on the deployment of blast resistant trash receptacles that focuses on the mitigation of human injury. It is not in general intended to provide guidance on the protection of structures in the vicinity of where the blast resistant trash receptacles are deployed.5.2 The importance of a strategy and procedures for the deployment of blast resistant trash receptacles in crowded places cannot be overly emphasized. Trash receptacles in crowded places have been, and continue to be, an attractive repository for explosives. The selection of deployment locations impacts both the mitigation of the effects of an explosion occurring within one as well as the convenience of using the receptacles.5.3 Two major effects resulting from an explosion in a trash receptacle are the production of primary and secondary fragments as well as overpressure from the detonation. The recommendations in this guide are intended to mitigate the damaging effects of fragmentation and overpressure in crowded places.5.4 Another effect resulting from an explosion in a trash receptacle is the fireball. This effect may cause burns to people caught within or near to the fireball. Also, it is possible that the heat output from an explosion may cause nearby combustible material to ignite. It is important, therefore, that blast resistant trash receptacles are not placed near combustible materials.5.5 The deployment of blast resistant trash receptacles provides a means for decreasing injury and lethality during an explosive event no matter their location when compared to the protection afforded by ordinary trash receptacles or clear plastic bags. Fragments resulting from explosions create the greatest danger to people as fragments may travel several hundred meters and still have velocities that could be lethal or injurious. Blast resistant trash receptacles that meet the requirements of Specification E2740 when subjected to internal explosions equal to or less than the force protection rating contain horizontal primary fragments and do not produce secondary fragments.5.6 This guide provides general provisions for the deployment of blast resistant trash receptacles. Every facility or venue has unique features associated with factors such as demographics, location, and functions. Operational and explosive effects considerations (see  Section 7) provide basic recommendations that may be sufficient for many facilities buildings and venues, but may not be specifically applicable to others. For example, special security concerns at high value facilities or high pedestrian count venues will require guidance concerning the deployment of blast resistant trash receptacles from security personnel familiar with that facility.5.7 The guide is intended for use by individuals in both the private and public sectors who are considering the purchase and deployment of blast resistance trash receptacles.1.1 This guide identifies the key factors that should be considered prior to the deployment of blast resistant trash receptacles (BRTRs) in crowded places.1.1.1 Guidance is included for their deployment at interior and exterior locations associated with the crowded places.1.2 Facilities and venues where blast resistant trash receptacles may be deployed include, but are not limited to:1.2.1 Airports,1.2.2 Banks and other financial institutions,1.2.3 Bars and nightclubs,1.2.4 Convention centers,1.2.5 Entertainment and event centers,1.2.6 Hotels,1.2.7 Health care locations,1.2.8 Museums,1.2.9 Places of worship,1.2.10 Public government locations including fire and police stations,1.2.11 Railway stations, bus stations, and related transit areas,1.2.12 Restaurants,1.2.13 Retail centers and malls,1.2.14 Schools, universities, and related areas used for education,1.2.15 Stadiums and arenas, and1.2.16 Theaters.1.3 Guidance on conducting a threat assessment or vulnerability analysis, and on responding to incidents associated with the deployment of blast resistant trash receptacles is beyond the scope of this document.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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.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.
