This Standard specifies the rating number method for evaluation of pitting corrosion of anodic oxide coatings (hereafter referred to as "coatings") on the products of aluminium or aluminium alloy (hereafter referred to as "products").

The rating number method evaluates the degree of pitting corrosion on the test pieces subjected to corrosion tests and outdoor exposure tests, and on products subjected to practical service tests, based on the rating number standard charts, and/or percentage area of corrosion Plts (%).

This Standard takes into account only pitting corrosion resulting from penetration of the coating.

NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 8993: 2010 Anodizing aluminium and its alloys-Rating system for the evaluation of pitting corrosion-Chart method (MOD)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
