This document specifies a grid rating system that provides a means of defining levels of performance of anodic oxidation coatings on aluminium and its alloys that have been subjected to corrosion tests.

This rating system is applicable to pitting corrosion resulting from

— accelerated tests,

— exposure to corrosive environments, and

— practical service tests.

This document takes into account only pitting corrosion of the basis metal resulting from penetration of the protective anodic oxidation coating.

NOTE 1 ISO 8993 describes a similar rating system based on defined chart scales.

NOTE 2 The grid rating system is frequently used for rating the results of short-term corrosion tests for relatively thin anodic oxidation coating, such as those used in the automotive industry.

This part of ISO 8504 describes methods for hand-tool and power-tool cleaning of steel substrates before application of paints and related products. It applies both to new steelwork and to steel surfaces that have been coated previously and that show areas of breakdown requiring maintenance painting. It describes the equipment to be used and the procedure to be followed.

This International Standard specifies the test methods for coating adhesion of sputtered silver layer coating for electrical, electronic, optical, and other engineering applications. Engineering applications are defined as those in which the coating essentially serves a non-decorative purpose.

Although the appearance and serviceability of the sputtered silver coating depends on the condition of the basis material, this International Standard does not specify the condition, finish or surface roughness of the basis material prior to the deposition. Therefore, it is essential that the purchaser shall specifies the surface finish and roughness of the basis material in order to confirm to the product requirements.

This International standard specifies the test methods of coatings on sheets and the flat objects, however, it does not apply to coatings on screw threads, strip or wire in the non-fabricated form.

This International Standard specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It is not applicable for chemical service glass-enamel and apparatus enamel.
