1.1 这种防火测试响应测试方法测量设计用于防火地板和墙壁的接缝系统在耐火测试暴露期间的性能。耐火试验终点是当接头系统经受两种时间-温度火灾暴露中的一种时，在达到第一性能标准之前经过的时间段。 1.2 使用的火灾暴露条件是试验方法规定的条件 E119 用于按照标准时间-温度暴露或测试方法测试组件 E1529 用于测试组件的快速升温火灾。 1.3 本试验方法规定了加热条件、试验方法和评估接头系统在满足每小时额定防火元件的情况下保持耐火能力的标准。1.4 测试结果确定了接头系统在火灾暴露期间的性能，不应被解释为已经确定了接头系统在火灾暴露后的适用性。 1.5 该测试方法不提供与烟雾或气体或两者的泄漏率相关的接头系统的定量信息。然而，它要求在描述耐火试验期间接头系统的一般行为时注意和报告此类现象，但不是合规条件的一部分。 1.6 本试验方法未涉及的潜在重要因素和火灾特性包括但不限于: 1.6.1 用测试部件以外的部件建造的耐火接头系统的性能。 1.6.2 测试的循环条件以外的关节系统的循环运动能力。1.7 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.8 本标准的正文参考了提供解释材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为标准的要求。 1.9 本标准用于测量和描述材料、产品或组件在受控条件下对热和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.10 火灾测试本质上是危险的。在进行这些试验时，应对人员和财产采取充分的安全措施。1.11 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。 1.12 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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 本试验方法在规定的试验条件下评价: (1) 耐火接头系统在不降低相邻防火分隔元件的防火等级的情况下经历移动的能力，以及 (2) 在预定的测试暴露期间，测试样本将包含火灾并保持其完整性的持续时间。 5.2 如果适用，本试验方法提供了以下测量和评价: 5.2.1 关节系统运动周期的能力。 5.2.2 连接系统的承载能力。 5.2.3 联合系统禁止火焰和热气体通过的能力。 5.2.4 通过关节系统传递热量。 5.2.5 接头系统（即壁的延伸）在软管水流测试期间抵抗水通过的能力。 5.3 本试验方法不提供以下内容: 5.3.1 评估联合系统通过产生烟雾、有毒气体或其他燃烧产物而导致火灾危险的程度。 5.3.2 烟或燃烧产物通过联合系统的控制或限制程度的测量。 5.3.3 测量在接头系统表面上蔓延的火焰。 附注1: 中的信息 5.3.1– 5.3.3 可以通过其他合适的防火测试方法来确定。例如， 5.3.3 可通过试验方法测定 E84 . 5.3.4 评估由建筑物的额定或非额定外墙和地板形成的接缝。 5.4 在该程序中，测试样本经受一组或多组特定的实验室测试条件。当替代不同的测试条件或改变最终使用条件时，并不总是能够通过或从该测试方法预测测量特性的变化。因此，结果仅对本试验方法中描述的暴露条件有效。

1.1 This fire-test-response test method measures the performance of joint systems designed to be used with fire rated floors and walls during a fire endurance test exposure. The fire endurance test end point is the period of time elapsing before the first performance criteria is reached when the joint system is subjected to one of two time-temperature fire exposures. 1.2 The fire exposure conditions used are either those specified by Test Method E119 for testing assemblies to standard time-temperature exposures or Test Method E1529 for testing assemblies to rapid-temperature rise fires. 1.3 This test method specifies the heating conditions, methods of test, and criteria for the evaluation of the ability of a joint system to maintain the fire resistance where hourly rated fire-separating elements meet. 1.4 Test results establish the performance of joint systems during the fire-exposure period and shall not be construed as having determined the joint systems suitability for use after that exposure. 1.5 This test method does not provide quantitative information about the joint system relative to the rate of leakage of smoke or gases or both. However, it requires that such phenomena be noted and reported when describing the general behavior of joint systems during the fire endurance test but is not part of the conditions of compliance. 1.6 Potentially important factors and fire characteristics not addressed by this test method include, but are not limited to: 1.6.1 The performance of the fire-resistive joint system constructed with components other than those tested. 1.6.2 The cyclic movement capabilities of joint systems other than the cycling conditions tested. 1.7 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. 1.8 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.9 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. 1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. 1.11 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. 1.12 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 evaluates, under the specified test conditions: (1) the ability of a fire resistive joint system to undergo movement without reducing the fire rating of the adjacent fire separating elements and (2) the duration for which test specimens will contain a fire and retain their integrity during a predetermined test exposure. 5.2 This test method provides for the following measurements and evaluations where applicable: 5.2.1 Capability of the joint system to movement cycle. 5.2.2 Loadbearing capacity of the joint system. 5.2.3 Ability of the joint system to prohibit the passage of flames and hot gases. 5.2.4 Transmission of heat through the joint system. 5.2.5 Ability of the joint system, that is an extension of a wall, to resist the passage of water during a hose stream test. 5.3 This test method does not provide the following: 5.3.1 Evaluation of the degree by which the joint system contributes to the fire hazard by generation of smoke, toxic gases, or other products of combustion. 5.3.2 Measurement of the degree of control or limitation of the passage of smoke or products of combustion through the joint system. 5.3.3 Measurement of flame spread over the surface of the joint system. Note 1: The information in 5.3.1 – 5.3.3 may be determined by other suitable fire test methods. For example, 5.3.3 may be determined by Test Method E84 . 5.3.4 Evaluation of joints formed by the rated or non-rated exterior walls and the floors of the building. 5.4 In this procedure, the test specimens are subjected to one or more specific sets of laboratory test conditions. When different test conditions are substituted or the end-use conditions are changed, it is not always possible by, or from, this test method to predict changes to the characteristics measured. Therefore, the results are valid only for the exposure conditions described in this test method.
