1.1 这些测试方法涵盖了油漆、清漆和清漆等有机涂料湿膜厚度的测定。两种方法描述如下: 1.1.1 在 试验方法A 湿膜厚度计（英制或公制刻度（见 5.1 ））用于测量英制刻度系列高达60密耳的湿膜厚度，以及公制刻度系列高达700 μ m的湿膜厚度（截面 5– 8 ). 1.1.2 在 试验方法B Pfund量具用于测量高达14.2密耳(360 μ m)的湿膜厚度（切片 9– 13 ). 1.2 以SI单位表示的值应被视为标准。括号中给出的值仅供参考。 1.3 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。1.4 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 湿膜厚度测量有助于预测干膜厚度。在无法无损测量干膜厚度的情况下，通常指定湿膜厚度。此外，在施加期间确定湿膜厚度的能力可以提供校正施加程序的机会。

1.1 These test methods cover the determination of wet film thickness of organic coatings such as paint, varnish, and lacquer. Two methods are described as follows: 1.1.1 In Test Method A , the Wet Film Thickness Gage (English or Metric graduation (see 5.1 )) is used to measure wet film thicknesses up to 60 mils on the English scale series, and up to 700 μm on the metric scale series (Sections 5 – 8 ). 1.1.2 In Test Method B , the Pfund Gage is used to measure wet film thicknesses up to 14.2 mils (360 μm) (Sections 9 – 13 ). 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. 1.4 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 Wet film thickness measurements aid in the prediction of dry film thickness. In instances where dry film thickness cannot be measured nondestructively, wet film thickness is frequently specified. Also, the ability to determine wet film thickness during application can provide the opportunity to correct the application procedures.
