意义和目的
4.1 湿膜厚度测量有助于预测干膜厚度. Wet film thickness is usually specified in cases where dry film thickness cannot be measured nondestructively. 此外, the ability to determine the wet film thickness during the application can provide the opportunity to correct the application.

范围
1.1 This test method includes the determination of wet film thickness of organic coatings such as paint, varnisher and lacquer. The two methods are described as follows:

1.1.1 In test method A, wet film thickness was measured using a wet film thickness gauge (in imperial or metric scale (看 5.1)) up to 60 mils in the imperial scale series and 700 μm in the metric scale series (Sections 5 — 8).

1.1.2 In test Method B, the Pfund Gage was used to measure wet film thickness up to 14.2 密耳 (360 micmeters) (Sections 9-13).
