Standard Test Method for Door Systems Subject to Airblast Loadings 受气体载荷影响的门系统的标准试验方法
发布日期: 2024-10-01
1.1 本试验方法确定了利用空气爆炸模拟器、激波管或受控露天爆炸评估门系统爆炸能力时应遵循的标准程序。该测试方法适用于所有类型的旋转门,包括单门和双门结构。该方法用于测试完整的门组件。门板还可以包含一个或多个整体视野窗(玻璃系统的一部分)。门组件的布置应使得初始冲击力作用于将门板固定到框架中或将门板从框架上移开以模拟爆炸威胁。当初始冲击力作用以将门从框架上移开时,力集中在约束硬件(即,闩锁机构、铰链和框架连接件)上。从该方法收集的结果可用于非刚性墙壁开口中的门安装。该测试方法可适用于水平滑动门和垂直升降门。 1.2 当用爆炸装药进行试验时,与试样接触的装药或任何导致高局部载荷的装药不在本方法范围内。当使用符合本标准的炸药进行试验时,为避免爆炸产生脆性响应模式,装药的比例范围应为(1.19 m/kg) 1/3 (3英尺/磅) 1/3 或更大,装药与试样的绝对最小间距为1 m(39英寸)。 1.3 可能需要抵抗或减轻爆炸影响的旋转门应具有限制硬件(闩锁机构和铰链)。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。门组件还可以包含辅助硬件。尽管这些关键约束和辅助物品中的许多被安装在被认为是门系统的“安全侧”上,但测试主管必须验证这些物品是否保持固定在组件上或从组件上移除。在试验过程中从门或门框上脱落并成为飞扬碎片危险的硬件项目应被指定为门响应损坏类别,如中所定义 表1 当门系统的测试结果不包括规范者规定的辅助硬件时,测试发起人或供应商/制造商应负责确定辅助部件成为飞行碎片危害的风险,使规范者满意。 1.4 除非最终用户另有规定,本测试方法和所得数据适用于所测试的门尺寸,以及具有相似(±20%)的相同结构的较小门(包括任何辅助硬件)纵横比最多缩小25%。验收标准分为五个门响应损坏类别(I、II、III、IV和V类)。损坏类别III有两个子类别:III/U允许在装载事件后门不安全,III/S要求在装载事件后门安全。参考 7.1 和 表1 对于每个类别的描述。 1.5 门组件还可以包含辅助硬件。尽管这些硬件部件可能不会影响防爆性能,但指定人员可能希望验证这些物品在测试期间不会从门或框架上脱落并成为飞溅碎片的危险。 1.6 对于装有vision lite的门,应使用中的门响应损坏类别对门进行评估 表1 以及vision lite的玻璃和玻璃系统也应使用中的玻璃危险级别进行评估 表2 (另见 7.5 ). 1.7 该方法旨在测试门组件在冲击波下的爆炸能力。它并不试图解决门组件所需的所有测试。这些测试可以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、声音衰减以及气体或水泄漏。本测试方法不包括这些类型的测试。 1.8 该测试方法不验证被测门将放置在其中的墙壁的防爆性能。 1.9 以SI单位(国际单位制)表示的数值应被视为标准。括号中给出的值仅供参考。 1.10 本标准并不旨在解决与其使用相关的所有安全性问题(如果有)。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 5.1 该测试方法提供了必须遵循的标准化程序,以确定特定门组件符合定义的损坏类别( 表1 ).测试结果可用于指定特定压力/时间负载和损坏水平的门组件。5.2 当门系统经受此测试方法时,并不意味着视觉上相似设计的门系统将抵抗相同的施加测试载荷。单个门组件抵抗其认证的指定鼓风压力的概率随着用于认证门设计的测试样本的数量而增加。见 附件A1 为了额外的统计考虑。 5.3 竞技场测试和激波管测试可能不会从一种方法转化为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,应咨询说明符。
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.
