Standard Test Method for Door Systems Subject to Airblast Loadings 承受气流冲击载荷的门系统的标准试验方法
发布日期: 2021-06-01
1.1 本试验方法确定了当使用空气冲击模拟器、激波管或受控露天爆炸来评估门系统的爆炸能力时应遵循的标准程序。本试验方法适用于所有类型的摆动门,包括单门和双门结构。该方法用于测试完整的车门组件。门板还可以包含一个或多个整体视觉光圈(玻璃系统的一部分)。门组件的布置应确保初始爆炸力作用于将门板固定到门框中,或将门板从门框中卸下,以模拟爆炸威胁。 当初始冲击力作用使门从门框上脱开时,力集中在约束硬件上(即锁紧机构、铰链和门框连接件)。从该方法收集的结果可用于非刚性墙开口中的门安装。试验方法可适用于水平滑动和垂直电梯门。 1.2 当使用爆炸装药进行测试时,与试样接触的装药或导致高局部载荷的任何装药不包括在本方法中。当按照本标准使用炸药进行测试时,为了避免爆炸引起的脆性反应模式,炸药的标度范围应为(1)。 19 米/千克) 1/3 (3 英尺/磅) 1/3 或更大,绝对最小值为1 m(39 in.)电荷与试样的距离。 1.3 可能需要抵抗或减轻爆炸影响的摆动门应具有约束硬件(闭锁机构和铰链)。这些项目的性能对于确定门组件的防爆或缓解性能至关重要。门组件也可以包含辅助硬件。尽管许多关键约束和辅助项目安装在车门系统的“安全侧”,但测试主管必须验证这些项目是否固定在总成上或从总成上脱落。 试验期间从门或框架上脱落并成为飞屑危险的硬件项目应被指定为门响应损坏类别,如 表1 . 当车门系统的测试结果不包括规范规定的辅助硬件时,测试发起人或供应商/制造商应负责确定辅助部件成为飞屑危险的风险,以满足规范的要求。 1.4 除非最终用户另有规定,否则本试验方法和结果数据适用于所试验的门尺寸,以及具有类似(±20 %) 纵横比高达25 % 更小 验收标准分为五个车门响应损坏类别(I、II、III、IV和V类)。损坏类别III有两个子类别:III/U允许在装载事件后安装未固定的门,III/S需要在装载事件后安装未固定的门。提到 7.1 和 表1 对于每个类别的描述。 1.5 门组件也可以包含辅助硬件。尽管这些硬件组件可能不会影响抗爆性能,但说明者可能希望验证这些项目在测试过程中不会从门或门框上脱落,并成为飞行碎片的危险。 1.6 对于配备vision lite的车门,应使用以下车门响应损坏类别对车门进行评估: 表1 ,并且还应使用中的玻璃危险等级评估vision lite的玻璃和玻璃系统 表2 (另请参见 7.5 ). 1.7 该方法旨在通过冲击波测试门组件的爆炸能力。它并不试图解决门组件所需的所有测试。这些测试可能包括但不限于装药接触爆炸阻力、强行进入阻力、弹道阻力、耐火性、声音衰减和气体或水泄漏。 本试验方法不包括这些类型的试验。 1.8 本试验方法不验证将放置测试门的墙体的爆破性能。 1.9 以国际单位制(国际单位制)表示的数值应视为标准。括号中给出的值仅供参考。 1.10 本标准并非旨在解决与其使用相关的所有安全问题(如有)。本标准的用户有责任在使用前制定适当的安全、健康和环境实践,并确定监管限制的适用性。 1.11 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法提供了必须遵循的标准化程序,以确定特定车门总成符合规定的损坏类别( 表1 ). 测试结果可用于指定特定压力/时间载荷和损坏等级的门组件。 5.2 当车门系统采用本试验方法时,并不意味着外观相似的车门系统将承受相同的施加试验载荷。随着用于验证门设计的试样数量的增加,单个门组件抵抗其认证的指定鼓风压力的概率增加。看见 附件A1 其他统计考虑。 5.3 Arena测试和激波管测试可能无法转化为一种方法到另一种方法的等效结果。说明符可能需要使用一种方法而不是另一种方法进行测试。在开始任何测试之前,应咨询规范。
1.1 This test method identifies the standard procedures that shall be followed when utilizing either an air blast simulator, shock tube, or a controlled open-air explosion to evaluate the blast capacity of a door system. This test method is designed for all types of swinging doors, including single and double doors construction. This method is used to test complete door assemblies. The door panel(s) may also contain one or more integral vision lites (part of the glazing system). The door assembly shall be arranged so that the initial blast force either acts to seat the door panel(s) into the frame or unseat the door panel(s) from the frame to simulate the blast threat. When the initial blast force acts to unseat the door(s) from the frame, the force is concentrated on the restraining hardware (that is, the latching mechanism, the hinges, and the frame connection). The results gathered from this method can be used for door installations in non-rigid wall openings. The test method may be adapted to horizontal sliding and vertical-lift doors. 1.2 When testing with an explosive charge, a charge in-contact with the test specimen or any charge resulting in high localized loading is not covered by this method. When testing with an explosive charge to this standard, to avoid brittle modes of response from the blast, the scaled range of the charge shall be (1.19 m/kg) 1/3 (3 ft/lb) 1/3 or greater from the test specimen, with an absolute minimum of 1 m (39 in.) standoff of the charge from the test specimen. 1.3 Swinging doors that may be required to resist or mitigate the effects of a blast shall have restraining hardware (latching mechanisms and hinges). The performance of these items is critical in determining the blast resisting or mitigating properties of a door assembly. A door assembly may also contain ancillary hardware. Although many of these critical restraining and ancillary items are mounted on what is deemed the “safe side” of the door system, the test director must verify whether these items stay affixed to the assembly or become dislodged from the assembly. Hardware items that dislodge from the door or frame during the test and become a flying debris hazard shall be assigned a door response damage category as defined in Table 1 . When the test results of a door system do not include ancillary hardware as specified by the specifier, it shall be the responsibility of the test sponsor or vendor/manufacturer to determine the risk of an ancillary component becoming a flying debris hazard to the satisfaction of the specifier. 1.4 Unless otherwise specified by end user, this test method and the resulting data are valid for the door size tested, and for smaller doors of identical construction (including any ancillary hardware) with a similar (±20 %) aspect ratio up to 25 % smaller. Acceptance criteria are divided into five door response damage categories (Categories I, II, III, IV, and V). Damage Category III has two subcategories: III/U that permits an unsecured door after the loading event and III/S that requires a secured door after the loading event. Refer to 7.1 and Table 1 for a description of each category. 1.5 A door assembly may also contain ancillary hardware. Although these hardware components may not influence blast resistance performance, the specifier may wish to verify that these items do not dislodge from the door or frame during a test and become a flying debris hazard. 1.6 For doors equipped with a vision lite, the door shall be evaluated using the door response damage categories in Table 1 , and the glazing and glazing system of the vision lite shall also be evaluated using the glazing hazard levels in Table 2 (see also 7.5 ). 1.7 This method is intended to test the blast capacity of a door assembly from a shock wave. It does not attempt to address all testing required of door assemblies. These tests may include, but are not limited to, charge-in-contact blast resistance, forced entry resistance, ballistic resistance, fire resistance, sound attenuation, and gas or water leakage. These types of tests are not covered by this test method. 1.8 This test method does not verify the blast performance of the wall that a tested door will be placed in. 1.9 The values stated in SI units (International System of Units) are to be regarded as the standard. The values given in parentheses are provided for information only. 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. ====== Significance And Use ====== 5.1 This test method provides standardized procedures that must be followed to establish that a particular door assembly meets a defined damage category ( Table 1 ). Test results can be used to specify a door assembly for a particular pressure/time loading and damage level. 5.2 When a door system is subjected to this test method, it does not imply that a door system of visually similar design will resist the same applied test load. The probability that a single door assembly will resist the specified air blast pressure for which it is certified increases with the number of test specimens used to certify the door design. See Annex A1 for additional statistical considerations. 5.3 Arena testing and shock tube testing may not translate to equivalent results from one method to the other. A specifier may require testing using one method instead of the other. The specifier should be consulted prior to the initiation of any testing.
