This document describes a classification of non-metallic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products. It specifies the characteristics which are required for the complete designation of such abrasives. This document applies to abrasives supplied in the "new" or unused condition only. It does not apply to abrasives either during or after use. NOTE Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504‑2.

This document specifies the requirements for qualification testing of welders for fusion welding of steels, aluminium, copper, nickel, titanium and zirconium.

In this document, the terms "aluminium", “copper”, “nickel”, “titanium” and “zirconium” refer to the materials and their alloys.

This document provides a set of technical rules for a systematic qualification test of the welder and enables such qualifications to be uniformly accepted independently of product type, location and examiner or examining body.

When qualifying welders, the emphasis is placed on the welder's ability to manually manipulate the electrode, welding torch, welding blowpipe, or laser gun, with or without filler material, to produce a weld of acceptable quality.

The fusion welding processes referred to in this document include welding processes which are designated as manual or partly mechanized.

This document does not cover fully mechanized and automated welding processes which are covered by ISO 14732.

The principles of this document can be applied to other fusion welding processes.

This document specifies test methods for the determination of the percentage of defective particles and of the microstructure of metallic blast-cleaning abrasives. This is one of a number of parts of ISO 11125 dealing with the sampling and testing of metallic abrasives for blast-cleaning. The types of metallic abrasive and requirements on each are contained in the various parts of ISO 11124. The ISO 11124 and ISO 11125 series have been drafted as a coherent set of International Standards on metallic blast-cleaning abrasives. Information on all parts of both series is given in Annex A.

This document gives guidelines for prevention of hydrogen assisted brittle fracture resulting from the manufacturing process (internal hydrogen embrittlement (IHE)). This document is applicable for parts or components made of high strength steels. It also advises on the relationship between material selection, manufacture including heat treatment, and coating.
