ISO/TC 20/SC 18 - Materials

This document specifies the requirements for technical procedures, quality inspection, etc. for the surface treatment of austenitic stainless steel parts (e.g. 300 series, AISI 651, A286 or equivalent). This document applies to the removal of organic and inorganic contaminants, surface cleaning, surface finishing and surface passivation before the non-destructive test of austenitic stainless steel parts.

This document specifies the requirements for technical procedures, quality inspection, etc. for the surface treatment of martensitic, precipitation hardening and maraging stainless steel parts (e.g.400 series, 17-7PH, 17-4PH, 15-5PH, AM350, AM355, PH15-7Mo, PH13-8Mo, Custom 450 and 455 or equivalent). It provides practical methods for removing contaminants and for obtaining suitable corrosion resistance for aerospace applications. This document applies to the removal of organic and inorganic contaminants, surface cleaning, surface finishing and surface passivation before non-destructive inspection of martensitic, precipitation hardening and maraging stainless steel parts.

This document specifies requirements for producing and testing an undyed sulfuric acid anodic coating on aluminium alloys. The anodizing process is applied in the manufacture of aerospace products to improve paint adhesion and resistance to corrosion.

This document specifies requirements for producing and testing a dyed sulfuric acid anodic coating on aluminium alloys. The anodizing process is applied in the manufacture of aerospace products to improve paint adhesion and resistance to corrosion and can colour the part in accordance with the drawing requirements.

This document specifies the requirements for producing and testing a general purpose chemical conversion coating on aluminium alloys. The chemical conversion coating is used in the manufacture of aerospace products in order to improve paint adhesion and resistance to corrosion. This process can also be used for touch-up of anodic coatings.

This document specifies the requirements for producing and testing an unsealed anodic coating on titanium and titanium alloys. The anodic coating is produced by the sulfuric acid process. The coating is used with solid film lubricants for protection of titanium fasteners against galling, for limited protection of less noble metals against galvanic corrosion when in contact with titanium or for other approved uses.

Specifies the requirements for parts made from martensitic, precipitation hardening and maraging stainless steels. Provides practical methods for removing contaminants and for obtaining suitable corrosion resistance for aerospace applications. The final surface treatments are mandatory except when a surface coating is specified.
