1.1 这些测试方法包括测定有机涂层（如油漆、清漆和油漆）的湿膜厚度。两种方法描述如下: 1.1.1 在里面 试验方法A ，湿膜测厚仪（英制或公制刻度）（参见 5.1 ))用于在英制刻度系列上测量高达60密耳的湿膜厚度，在公制刻度系列上测量高达700μm的湿膜厚度（第 5 – 8. ). 1.1.2 在里面 试验方法B ，Pfund量规用于测量高达14.2密耳（360μm）的湿膜厚度（截面） 9 – 13 ). 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 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。 1.4 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，通常会指定湿膜厚度。此外，在涂覆过程中确定湿膜厚度的能力可以提供纠正涂覆程序的机会。

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.
