The standard specifies a method for testing defects and mechanical damage in metallic coatings using phosphomolybdic acid (PMA). The PMA test is mainly used to detect abrasion and mechanical damage present in coatings, especially in exposed parts of copper or copper alloy substrates. The test is less sensitive to small pores and does not predict product performance, but is effective in identifying serious defects and abrasions in coatings.
