The ASTM D4414-95 (2020) standard implementation procedure provides a reliable method for the measurement of wet film thickness using a notch meter. The procedure is suitable for various Coatings and liquid coatings. By measuring wet film thickness, the uniformity of coatings and the realization of design thickness are ensured. The standard details the type of notch meter, the steps of use, the requirements of Measurement accuracy and the treatment method of common errors to ensure the repeatability and accuracy of test results. This method is widely used in Coatings production, construction site and quality control links, which can help users optimize coating process, reduce material waste, and improve the performance and service life of coatings.
