ASTM D5402-19 is a standard practice designed to evaluate the tolerance of organic coatings that undergo chemical changes during curing to solvents. Coatings are required to achieve specific levels of solvent resistance during the curing process to guarantee their performance in top coating and actual use. This practice describes methods for evaluation using solvent friction techniques, which can be applied in the laboratory, field, or manufacturing floor. Different types of Coatings and solvents used can have an impact on test results, so Coating manufacturers can specify the type of solvent required for testing, number of wipes, and specific test results on a case-by-case basis. The purpose of this standard is to follow the principles of international standards and provide a uniform test method for the Coatings industry to ensure that Coatings achieve an acceptable level of solvent resistance before use.
