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.

Related standards

• ISO 11124 series (other metallic abrasive specifications)
• Test methods: ISO 11125‑1 to ISO 11125‑7
• Chemical analysis standards: ISO 439, ISO 629, ISO 9556, ISO 4935, ISO 10714
• Annex A of EN ISO 11124‑5 provides cross‑references to national grade codings.

Keywords: EN ISO 11124-5:2021, cut steel wire abrasive, metallic blast-cleaning abrasives, surface preparation, blast cleaning, hardness, particle size, apparent density, virgin wire.
