1.1 本实验室试验方法涵盖使用詹姆斯机器测量抛光涂层地板表面的静态摩擦系数，以确保人的移动安全。此外，该试验方法还建立了符合性标准，以满足非危险抛光走道表面的要求。试验方法不适用于“潮湿”表面或表面雕刻图案之间的纹理、投影、轮廓或间隙不允许机器底座和试验表面之间充分接触的表面。 1.2 本试验方法是唯一适用于测试抛光剂规格是否符合地板抛光剂静态摩擦系数标准的方法。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 试验方法 D2047 建立了地板表面静态摩擦系数测量值与人体移动安全性之间的符合性标准。合规标准基于1942年以来住宅、商业、工业和机构走道表面的大量经验数据。 4.2 根据本试验方法测量，静态摩擦系数不小于0.5的抛光剂和其他地板维护涂层被认为提供了无危险的走道。 注1: 0.5的值符合联邦贸易委员会1953年3月17日发布的地板蜡和地板抛光行业拟议贸易惯例规则第5条“使用防滑、防滑或类似进口条款”的要求。 4.3 本试验方法的0.5静态摩擦系数顺应性标准仅适用于根据本机器和试验方法进行试验的抛光涂层表面。将该符合性标准用于其他测试方法、其他测试仪器和其他表面是不合适的，因为它们不是符合性标准所依据的经验数据体的一部分。 注2: 本测试方法的一致性标准可能适用于通过本测试方法测试的其他表面和表面涂层，但这尚未通过与经验数据的相关性得到证实。

1.1 This laboratory test method covers the use of the James Machine for the measurement of the static coefficient of friction of polish-coated flooring surfaces with respect to human locomotion safety. Further, this test method also establishes a compliance criterion to meet the requirement for a nonhazardous polished walkway surface. The test method is not intended for use on “wet” surfaces or on surfaces wherein the texture, projections, profile or clearance between the sculptured pattern of the surface does not permit adequate contact between the machine foot and the test surface. 1.2 This test method is the only method appropriate for testing polishes for specification compliance with the floor polish static coefficient of friction criterion. 1.3 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. 1.4 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. 1.5 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 Test Method D2047 establishes a compliance criterion relating static coefficient of friction measurements of flooring surfaces with human locomotion safety. The compliance criterion is based on extensive experiential data from residential, commercial, industrial and institutional walkway surfaces since 1942. 4.2 Polishes and other floor maintenance coatings having a static coefficient of friction of not less than 0.5, as measured by this test method, have been recognized as providing nonhazardous walkways. Note 1: The value of 0.5 meets the requirements for compliance with Rule 5 on “The use of terms slip retardant, slip resistant, or terms of similar import,” of the Proposed Trade Practice Rules for the Floor Wax and Floor Polish Industry as issued by the Federal Trade Commission on March 17, 1953. 4.3 The 0.5 static coefficient of friction compliance criterion of this test method is only appropriate for polish-coated surfaces tested in accordance with this machine and test method. The use of this compliance criterion with other test methods, other test instruments, and other surfaces is improper, because they are not a part of the body of experiential data upon which the conformance criterion is based. Note 2: The conformance criteria of this test method may be valid for other surfaces and surface coatings tested by this test method, but this has not been substantiated by correlation with experiential data.
