1.1 作为消防试验响应标准的一部分，本规程适用于需要承受软管流冲击、侵蚀和冷却作用的建筑构件。建筑构件包括但不限于墙壁和隔墙组件、防火接头系统和门。 1.2 本规程应记录建筑构件在特定软管流条件下的性能。这并不意味着暴露后或在其他条件下，建筑构件的结构能力是完整的，也不意味着建筑构件适合使用。 1.3 这种做法得出的结果是评估火灾暴露后建筑构件完整性的一个因素。该规程规定了标准软管流暴露量，用于比较火灾暴露后建筑构件的性能，并在常见条件下评估各种材料和施工技术。 1.4 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.5 本标准的文本引用了提供解释性材料的注释。这些注释不应被视为本标准的要求。 1.6 该消防标准不能用于提供定量措施。 1.7 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.8 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====== 4.1 本规程旨在将所使用的设备以及标准软管流应用于建筑构件的方法或模式标准化，作为建筑构件评估和耐火性的一部分。 4.1.1 本规程规定了水压和软管流应用于试验组件的持续时间。 4.2 本规程仅在试验组件完成规定的标准耐火试验后使用。 4.3 该实践将测试组件暴露在受控实验室条件下的标准软管流中。 4.3.1 合格/不合格标准在适当的防火试验方法中进行了定义。 4.3.2 这种暴露不是为了复制典型的消防操作，也不是为了复制系统在现场使用和条件下可能受到的所有施加或冲击载荷。 4.4 测试条件的任何变化都有可能显著改变本实践确定的性能特征。

1.1 This practice is applicable to building elements required to be subjected to the impact, erosion, and cooling effects of a hose stream as part of a fire-test-response standard. Building elements include, but are not limited to, wall and partition assemblies, fire-resistive joint systems, and doors. 1.2 This practice shall register performance of the building element under specific hose stream conditions. It shall not imply that, either after exposure or under other conditions, the structural capability of the building element is intact or that the building element is suitable for use. 1.3 The result derived from this practice is one factor in assessing the integrity of building elements after fire exposure. The practice prescribes a standard hose stream exposure for comparing performance of building elements after fire exposure and evaluates various materials and construction techniques under common conditions. 1.4 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. 1.5 The text of this standard references notes which provide explanatory material. These notes shall not be considered as requirements of the standard. 1.6 This fire standard cannot be used to provide quantitative measures. 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. ====== Significance And Use ====== 4.1 This practice is intended to standardize the apparatus used and the method or pattern of application of a standard hose stream to building elements as one part of the assessment and fire resistance of building elements. 4.1.1 This practice specifies the water pressure and duration of application of the hose stream to the test assembly. 4.2 This practice is intended to be used only after a test assembly has completed a prescribed standard fire-resistance test. 4.3 The practice exposes a test assembly to a standard hose stream under controlled laboratory conditions. 4.3.1 Pass/fail criteria are defined in the appropriate fire test method. 4.3.2 This exposure is not intended to replicate typical fire fighting operations or all applied or impact loads a system could be subjected to in field use and conditions. 4.4 Any variation from tested conditions has the potential of substantially changing the performance characteristics determined by this practice.
