1.1 本试验方法涵盖了大多数纺织材料厚度的测量。 1.2 本试验方法适用于大多数织物，包括机织物、气囊织物、毯子、绒布织物、针织物、分层织物和绒布。织物可以是未经处理的、大尺寸的、涂层的、树脂处理的或其他处理的。提供了测试厚度的说明，但第节列出的其他标准中另有规定的除外 2. . 1.3 以国际单位制表示的数值应视为标准。以英寸-磅表示的数值可能是近似值。 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====== 5.1 由于实验室间精度的当前估计值是可接受的，因此该测试方法被认为是商业货物验收测试的满意方法，并且该测试方法在验收测试行业中广泛使用。 5.1.1 如果使用本测试方法进行商业装运验收测试时，由于报告测试结果的差异而产生争议，买方和供应商应进行比较测试，以确定其实验室之间是否存在统计偏差。 建议为调查偏差提供称职的统计协助。作为最低要求，双方应尽可能均匀地从大量相关类型的材料中选取一组试样。然后，应将试样以相同数量随机分配给每个实验室进行测试。在开始测试之前，应使用适当的统计分析和双方选择的可接受概率水平对两个实验室的平均结果进行比较。如果发现偏差，必须找到并纠正其原因，或者买方和供应商必须同意在考虑已知偏差的情况下解释未来的测试结果。 5.2 厚度是纺织材料的基本物理性能之一。在某些工业应用中，厚度可能需要严格控制在规定范围内。 纺织材料的体积和保暖性能通常根据其厚度值进行估计，厚度也有助于测量一些性能特征，例如磨损和收缩前后。 5.3 大多数纺织材料的厚度值会因进行厚度测量时施加在试样上的压力而发生很大变化。在所有情况下，表观厚度与施加的压力成反比。因此，在讨论或列出任何厚度值时，必须指定压力。 5.4 当使用本试验方法测量纺织材料的厚度时，除非该试验方法中另有规定，否则参考文件章节中列出的特定材料的主要方法应优先于本试验方法中描述的方向。 除非材料规范或合同订单中另有规定，否则当没有用于测量待测试特定材料厚度的测试方法时，应全部使用本测试方法。

1.1 This test method covers the measurement of the thickness of most textile materials. 1.2 This test method applies to most fabrics including woven fabrics, air bag fabrics, blankets, napped fabrics, knitted fabrics, layered fabrics, and pile fabrics. The fabrics may be untreated, heavily sized, coated, resin-treated, or otherwise treated. Instructions are provided for testing thickness, except as provided for in another standard such as listed in Section 2 . 1.3 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound may be approximate. 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 is considered satisfactory for acceptance testing of commercial shipments since current estimates of between-laboratory precision are acceptable, and this test method is used extensively in the trade for acceptance testing. 5.1.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. Test specimens then should be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using the appropriate statistical analysis and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected, or the purchaser and the supplier must agree to interpret future test results with consideration to the known bias. 5.2 Thickness is one of the basic physical properties of textile materials. In certain industrial applications, the thickness may require rigid control within specified limits. Bulk and warmth properties of textile materials are often estimated from their thickness values, and thickness is also useful in measuring some performance characteristics, such as before and after abrasion and shrinkage. 5.3 The thickness value of most textile materials will vary considerably depending on the pressure applied to the specimen at the time the thickness measurement is taken. In all cases, the apparent thickness varies inversely with the pressure applied. For this reason, it is essential that the pressure be specified when discussing or listing any thickness value. 5.4 When using this test method for measuring the thickness of textile materials, the primary method for the specific material such as listed in the Referenced Document section shall take precedence over the directions described in this test method, unless specifically provided for in that test method. This test method is used in its entirety when no test method for measuring thickness is available for the specific material to be tested or unless otherwise specified in a material specification or contract order.
