BS EN ISO 11124-5:2021

This standard BS EN ISO 11124-5:2021 Preparation of steel substrates before application of paints and related products. Specifications for metallic blast-cleaning abrasives is classified in these ICS categories:

• 25.220.10 Surface preparation

This document specifies requirements for 13 grades of cut steel wire abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements, metallographic structure and chemical composition.

This document is suitable for cut steel wire supplied for blast-cleaning processes which is made by cutting new cold drawn wire.

The requirements specified in this document apply to abrasives manufactured from virgin wire supplied in the new and unconditioned state only. They do not apply to abrasives either during or after use.

NOTE 1 Information on commonly referenced national standards for cut steel wire abrasives and their approximate relationship with ISO 11124 is given in Annex A.

NOTE 2 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.
