DIN EN ISO 10309:2016-08

This International Standard specifies a method of revealing pores or other discontinuities, when testing metallic coatings, that are not visibly affected by ferricyanide and chloride ions during the test period and that are cathodic to iron and steel. This method is especially useful for thick, hard chromium coatings used for wear resistance. The text of ISO 10309:1994 has been prepared by Technical Committee ISO/TC 107 "Metallic and other inorganic coatings" of the International Organization for Standardization (ISO) and adopted as EN ISO 10309:2016 by Technical Committee CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI. The responsible German standardization committee is Working Committee NA 062-01-61 AA "Mess- und Prüfverfahren für metallische und andere anorganische Überzüge" ("Measuring and test methods for metallic and other inorganic coatings") at DIN Standards Committee Materials Testing (NMP).
