1.1 本试验方法涵盖了在承受集中载荷时确定弹性地板短期压痕和残余压痕的程序。 1.2 测试方法按以下顺序出现: 部分 McBurney缩进 2. 测验 4. 到 10 压痕和残余压痕 11 到 15 1.3 有两个程序，分别使用各自的设备。第一个（McBurney试验）在第节中进行了描述 4. 到 10 并且被限制为球形脚部。它仅用于VCT的初始压痕测量。 第二个在第节中进行了描述 11 到 15 并且具有可变几何形状的可互换脚。它用于测量初始压痕和残余压痕。 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。 1.6 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====== 11.1 弹性地板覆盖物的压痕和残余压痕是重要的，因为压痕的阻力和恢复反映了弹性地板覆盖件在安装后正常工作的能力。 11.2 弹性地板覆盖物的压痕应使用指定类型的压痕仪（平面或球形）在指定的载荷和时间下进行测量。 11.3 弹性地板覆盖物的残余压痕应在规定的恢复时间后进行测量。 11.4 看见 表1 按产品（规格）类型进行详细的测试和调节要求。

1.1 This test method covers procedures to determine short-term indentation and residual indentation of resilient flooring, when subjected to concentrated loads. 1.2 The test methods appear in the following order: Section Indentation by McBurney 2 Test 4 to 10 Indentation and Residual Indentation 11 to 15 1.3 There are two procedures with their respective apparatus. The first (McBurney Test) is described in Sections 4 to 10 and is restricted to a spherical foot. It is only used for initial indentation measurements of VCT. The second is described in Sections 11 to 15 and has interchangeable feet with variable geometry. It is used to measure initial and residual indentation. 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 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. 1.6 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 ====== 11.1 The indentation and the residual indentation of resilient floor covering is important since the resistance and recovery from indentation reflects on the ability of the resilient floor covering to perform properly after installation. 11.2 The indentation of a resilient floor covering shall be measured using a specified type of indentor, flat or spherical, under a specified load and time. 11.3 The residual indentation of a resilient floor covering shall be measured after a specified recovery time. 11.4 See Table 1 for detailed testing and conditioning requirements by products (specification) type.
