6.3 Assignment of the performance ratingAs stated in 2.5, the performance rating is the combination of the protection rating (R p ) followed by a slash mark,followed by the appearance rating (R A ). Examples of reporting the performance rating are:a) Specimens showing base metal corrosion over 0,1 % of the total area and the remaining surface of thespecimen showing moderate staining over 20 % of the area: 9/2 m A.b) Specimens showing no base metal corrosion but showing slight corrosion of the anodic coating less than 1 ,0 %of the area: 1 0/6 s C.c) Specimens showing 0,3 % area of base metal corrosion (R p = 7), also showing corrosion products from ananodic coating covering 0,1 5 % of total area, and very slight blistering of the top electroplated layer over 0,75 %of the total area (but not extending to the base metal): 7/8 vs C, 6 m G.
