1.1 本实施规程描述了在测试现场制造的拉伸系统时样品制备和安装的程序，以使用测试方法评估火焰传播和烟雾形成的表面燃烧特性 E84 . 1.2 按照测试方法进行测试 E84 . 1.3 此做法未提供可作为监管工具的合格/不合格标准。 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。 看见 IEEE/atm SI-10 以了解更多详细信息。 1.5 该消防标准不能用于提供定量措施。 1.6 产品和材料的防火测试具有固有的危险性，在进行这些测试时，应为人员和财产提供足够的保护。火灾测试涉及危险材料、操作和设备。本标准给出了试样制备和安装的说明，但试验方法中给出了火灾试验响应方法 E84 。另请参见第节 10 . 1.7 本规程不适用于本规程涵盖的乙烯基拉伸天花板材料 E2599 . 1.8 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。 1.9 本标准的文本引用了提供解释性材料的注释和脚注。 这些注释和脚注不应被视为本标准的要求。 1.10 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 使用试验方法对用作内部饰面的现场制造拉伸系统进行评估 E84 以符合建筑、消防或生命安全规范的要求。本规程描述了此类材料和系统的试样制备和安装程序。 5.2 本程序的限制是与试验方法相关的限制 E84 . 5.3 其他限制-- 本规程不适用于不能用于生产自支撑试样的试验系统。如果试样不是自支撑的，可以在试验方法的附录A4中找到进一步的指导 E84 . 5.4 本规程不适用于本规程涵盖的乙烯基拉伸天花板材料 E2599 .

1.1 This practice describes procedures for specimen preparation and mounting when testing a site-fabricated stretch system to assess flame spread and smoke developed as surface-burning characteristics using Test Method E84 . 1.2 Testing is conducted with Test Method E84 . 1.3 This practice does not provide pass/fail criteria that can be used as a regulatory tool. 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. See IEEE/ASTM SI-10 for further details. 1.5 This fire standard cannot be used to provide quantitative measures. 1.6 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. Fire testing involves hazardous materials, operations, and equipment. This standard gives instructions on specimen preparation and mounting, but the fire-test-response method is given in Test Method E84 . See also Section 10 . 1.7 This practice shall not apply to vinyl stretch ceiling materials, which are covered by Practice E2599 . 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 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes shall not be considered requirements of the standard. 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. ====== Significance And Use ====== 5.1 Site-fabricated stretch systems used as interior finish are evaluated with Test Method E84 to comply with building, fire, or life safety code requirements. This practice describes specimen preparation and mounting procedures for such materials and systems. 5.2 The limitations for this procedure are those associated with Test Method E84 . 5.3 Additional Limitations— This practice does not apply to test systems that cannot be used to produce self-supporting specimens. If the test specimen is not self-supporting, further guidance can be found in Annex A4 of Test Method E84 . 5.4 This practice shall not apply to vinyl stretch ceiling materials, which are covered by Practice E2599 .
