ASTM D610-08 (2019) standard practice is designed to evaluate the degree of rusting on painted steel surfaces. The standard provides a standardized method by quantifying the amount and distribution of rust on visible surfaces. The degree of rusting is assessed on a scale of 0 to 10 based on the percentage of rusting, classified as spot rust, general rust, tip rust, or mixed rust. The standard includes visual examples developed in collaboration with SSPC for further standardization of the method that can help estimate the percentage of Miscellaneous coating defects. However, this standard does not cover the assessment of scratches, scores, or rust extensions around holidays. Users using this standard need to ensure appropriate safety, health, and environment practices and confirm the restrictive requirements of applicable regulations.
