1.1弹性地板制造中涉及的两个重要特征与磨损表面的平滑度和磨损表面下各层的硬度有关。表面可能从完全纹理区域变化到平坦但由纹理区域分隔的部分。本试验方法涵盖了具有这些中断磨损表面的地板，这些表面不由柔软的缓冲层支撑。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法旨在测量地板表面任何两个标高之间的垂直距离，即任何两个平面区域之间、平面区域与纹理区域任何部分之间或两个纹理区域之间的垂直距离。这种垂直距离本身可能有意义，也可能适用于以下问题:( 1. )在破坏图案之前，地板的厚度有多大； 或( 2. )凹地有多深，才能使凹地油墨不在正常交通中行走。

1.1 Two important characteristics involved in the manufacture of resilient flooring relate to the smoothness of the wear surface and the hardness of the layers under the wear surface. The surfaces may vary from completely textured areas to portions that are flat but separated by textured areas. This test method covers flooring with these interrupted wear surfaces which are not supported by soft, cushioned layers. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method is designed to measure the vertical distance between any two levels on the face of the flooring, that is, between any two flat areas, between a flat area and any part of a textured area, or between two textured areas. This vertical distance may be of interest in itself or it may be applied to the questions of: ( 1 ) how much of the thickness of the flooring is available before the pattern is destroyed; or ( 2 ) how deep the depressed areas must be before valley printing ink is not walked on in normal traffic.
