Description (English):

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.

Abstract

Overview

EN ISO 11124-5:2021 (ISO 11124-5:2019) specifies requirements for cut steel wire abrasives used in blast-cleaning and surface preparation. The standard covers 13 graded sizes of abrasive made by cutting new cold-drawn wire (virgin wire) and defines particle size ranges, grade designations, and required physical, metallurgical and chemical properties. It is intended for suppliers, specifiers and users of metallic blast-cleaning abrasives for preparing steel substrates (and is generally applicable to other materials prepared by blast cleaning).

Key topics and technical requirements

Grade system and designation: 13 grades from C250 down to C030 (nominal wire diameters 2.5 mm to 0.3 mm). Product designations use the format e.g. Abrasive ISO 11124 M/CW/C100 (M/CW/C080/570–710HV optionally to indicate hardness).
Particle size / mass: Each grade has specified nominal sizes and corresponding mass ranges for a sample number of particles (see Table 1 in the standard).
Hardness: Standard hardness ranges required for ≥90% of particles:
- 390 HV–520 HV
- 470 HV–610 HV
- 570 HV–710 HV
- ≥700 HV (special)
Apparent density: Minimum specified apparent density (example: min. 7.8 g/cm3) tested per ISO 11125‑4.
Defects, microstructure and composition: Limits and test methods are given for defective/over‑length particles, cracks, metallographic structure and chemical composition; chemical determinations reference ISO methods (e.g., ISO 439, ISO 629, ISO 9556, ISO 4935, ISO 10714).
Sampling and test methods: Sampling per ISO 11125‑1; hardness, density, defect, moisture and foreign matter test methods referenced in ISO 11125‑3 to ISO 11125‑7.
Traceability and marking: Requirements for package identification, lot traceability and information suppliers must provide (grade, hardness, batch, manufacturer data).
Scope limit: Applies only to abrasives manufactured from virgin, new and unconditioned cold‑drawn wire; does not apply to abrasives during/after use.

Applications and users

Who benefits from EN ISO 11124-5:2021:

Abrasive manufacturers - to certify product grades and test methods.
Surface preparation contractors and blasters - to select the correct cut‑wire abrasive for steelwork cleaning.
Coating specifiers and paint manufacturers - to specify appropriate abrasives for substrate preparation and coating performance.
Asset owners / engineering firms - bridges, shipyards, offshore structures, tanks and industrial plants where consistent blast‑cleaning performance and traceability are required.
Testing laboratories and quality assurance teams - to perform mandated sampling and acceptance tests.

Test methods: ISO 11125‑1 to ISO 11125‑7
Chemical analysis standards: ISO 439, ISO 629, ISO 9556, ISO 4935, ISO 10714
