The ASTM D3451-2017 standard provides a summary of procedures and methods for testing Coatings powders and powder coatings. Applies to thermal plasticity and thermosetting coatings, but does not include functional powder coatings developed specifically for piping or reinforcing steel bars. The guide lists various test methods, such as gel time and inclined flow, and is designed to help select the appropriate test procedure. The interpretation of results needs to be based on the specific application and material chemistry. This standard also refers to methods from the Powder Coatings Institute (PCI) and the international standards organization (ISO). Test methods include electrostatic spraying, fluidized beds, etc.
