1.1 该试验方法包括测量地板表面轮廓的定量方法，以获得地板特性的估计值 F F 平坦度和 F L 水平面楼层剖面编号( F -数字）。 1.2 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且不得将两个系统的值组合使用。 1.3 本测试方法的文本引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应被视为本试验方法的要求。 1.4 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。 1.5 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 该测试方法提供了有关地板表面轮廓的统计（和图形）信息。 5.2 该试验方法的结果主要用于: 5.2.1 确定随机通行的地板表面是否符合规定 F F 平坦度和 F L 水平度公差， 5.2.2 评估不同施工方法对地板表面平整度和水平度的影响，以及 5.2.3 调查地板表面的卷曲和偏斜情况。 5.3 本试验方法的结果不得用于对主要用于支持固定路径车辆系统运行的地板安装（例如，狭窄通道仓库地板）执行合同平面度和水平度公差。 注1: 当一个楼层的交通模式是随机的时，（通常情况下）对楼层的评估 F F 平坦度和 F L 水平度必然涉及表面的随机采样，因为不可能测量交通所看到的所有无限电位剖面。然而，在那些情况下，当穿过地板的交通将被限制在特定路径上时，随机采样的要求被取消了，因为地板确实可以像所有交通所看到的那样被检查。在这些特殊情况下，与其从随机样本推断交通路径的状况，不如直接使用被配置为精确地在交通车轮路径中运行的连续记录地板轮廓仪来测量每条交通路径。这种直接模拟测量消除了统计采样的固有不确定性，并提供了可立即应用于未来交通中的表面校正的剖面信息。

1.1 This test method covers a quantitative method of measuring floor surface profiles to obtain estimates of the floor’s characteristic F F Flatness and F L Levelness Face Floor Profile Numbers ( F -Numbers). 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.3 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method. 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 ====== 5.1 This test method provides statistical (and graphical) information concerning floor surface profiles. 5.2 Results of this test method are used primarily to: 5.2.1 Establish compliance of randomly trafficked floor surfaces with specified F F Flatness and F L Levelness tolerances, 5.2.2 Evaluate the effect of different construction methods on resulting floor surface flatness and levelness, and 5.2.3 Investigate the curling and deflection of floor surfaces. 5.3 Results of this test method shall not be used to enforce contract flatness and levelness tolerances on those floor installations primarily intended to support the operation of fixed-path vehicle systems (for example, narrow aisle warehouse floors). Note 1: When the traffic patterns across a floor are random, (as is generally the case) evaluation of the floor’s F F Flatness and F L Levelness will necessarily involve a random sampling of the surface, since all of the infinite potential profiles to be seen by the traffic can not possibly be measured. In those instances when the traffic across a floor will be confined to specific paths, however, the requirement for random sampling is eliminated, since the floor can indeed be inspected exactly as it will be seen by all of the traffic. In these special cases, rather than inferring the condition of the traffic paths from a random sample, it is far more useful to measure each of the traffic paths directly using continuous recording floor profilometer configured to run exactly in the traffic wheel paths. Such direct simulation measurements eliminate the inherent uncertainties of statistical sampling and provide profile information immediately applicable to the correction of the surface in way of the future traffic.
