1.1 本实施规程描述了测试木制品时样品制备和安装程序，以使用测试方法评估火焰蔓延和烟雾发展作为表面燃烧特性 E84 或测试方法 E2768 。 1.1.1 试验方法 E2768 使用与测试方法相同的测试设备 E84 。 1.2 本规程也适用于工厂使用木质基材生产的层压产品（参见 8.6 )。本规程不适用于本规程涵盖的拟在现场应用于木质基材上的木贴面或饰面 E2404 。 1.3 采用测试方法进行测试 E84 或采用测试方法 E2768 。 1.4 试样含水量报告的试验采用试验方法进行 D4442 。 1.5 本规程未提供可用作监管工具的合格/不合格标准。 1.6 单位-- 在裁判裁决中，使用以英寸-磅为单位的数值作为标准。括号中给出了国际单位制中的数值，仅供参考；看见 IEEE/atm SI-10 了解更多详细信息。 1.7 该消防标准不能用于提供定量措施。 1.8 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。 1.9 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 ，或在测试方法中 E2768 ，视情况而定。另请参见第节 10 。 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。 1.11 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 木制品的表面燃烧特性通常用试验方法进行评估 E84 以符合规范要求。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 如果可以证明本规程中描述的任何方法都不适用于特定的木制品，则应允许使用其他安装方法。该信息应包含在报告中。 5.3 本程序的限制是与试验方法相关的限制 E84 。

1.1 This practice describes procedures for specimen preparation and mounting when testing wood products to assess flames spread and smoke development as surface burning characteristics using Test Method E84 or Test Method E2768 . 1.1.1 Test Method E2768 uses the same test equipment as Test Method E84 . 1.2 This practice applies also to laminated products factory-produced with a wood substrate (see 8.6 ). This practice does not apply to wood veneers or facings intended to be applied on site over a wood substrate, which are covered by Practice E2404 . 1.3 Testing is conducted with Test Method E84 or with Test Method E2768 . 1.4 Testing for the reporting of the moisture content of the test specimen is conducted with Test Methods D4442 . 1.5 This practice does not provide pass/fail criteria that can be used as a regulatory tool. 1.6 Units— Use the values stated in inch-pound units as the standard, in referee decisions. The values in the SI system of units are given in parentheses, for information only; see IEEE/ASTM SI-10 for further details. 1.7 This fire standard cannot be used to provide quantitative measures. 1.8 The text of this standard references notes and footnotes which provide explanatory materials. These notes and footnotes shall not be considered requirements of the standard. 1.9 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 and equipment. This standard gives instructions on specimen preparation and mounting, but the fire-test-response method is given in Test Method E84 , or in Test Method E2768 , as appropriate. See also Section 10 . 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 The surface burning characteristics of wood products are often evaluated with Test Method E84 to comply with code requirements. This practice describes specimen preparation and mounting procedures for such materials and systems. 5.2 If it can be demonstrated that none of the methods described in this practice are applicable to a particular wood product, other mounting methods shall be permitted to be used. This information shall be included in the report. 5.3 The limitations for this procedure are those associated with Test Method E84 .
