Which standard is often referenced for measuring DFT in coatings?

The ASTM D7091 standard is specifically designed for measuring the dry film thickness (DFT) of protective coatings. This standard outlines the procedures and techniques for assessing DFT accurately, ensuring that coatings perform as expected in terms of protection and durability. Measuring DFT is crucial in various industries, particularly in those that deal with protective coatings for structures and machinery, as it can significantly influence the coating's effectiveness.

In contrast, other standards listed, such as ISO 9001, focus on quality management systems rather than specific measurement techniques for coatings. ANSI Z535 deals with safety signs and colors, while OSHA 1910 encompasses occupational safety and health standards, none of which are directly related to the measurement of DFT in coatings.
