Description (English):

This document specifies requirements for 12 grades of chilled-iron grit 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 and chemical composition. The requirements specified in this document apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for metallic blast-cleaning abrasives are given in the various parts of ISO 11125. Chilled-iron grit abrasives are used in both static and site blasting equipment. They are most often selected where a facility exists for recovery and re-use of the abrasive. 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.

Abstract

Overview

EN ISO 11124-2:2018 specifies requirements for chilled‑iron grit used as metallic blast‑cleaning abrasives in the preparation of steel substrates before painting and related coatings. The standard defines 12 graded sizes (nominal particle sizes expressed by grade codes such as M/CI/G100) and sets mandatory properties for abrasives supplied in the new condition, including particle size distribution, hardness, apparent density, defect/structural limits and chemical composition.

Key topics and technical requirements

Grade and particle size: Twelve grade designations with defined particle size ranges (grade numbers indicate the nominal diameter × 100, e.g. G100 ≈ 1.00 mm). Full screening specifications are given in the standard.
Hardness: Specified minimum hardness requirements (for example, 90% of particles shall exceed 650 HV as per the standard test).
Density and defects: Apparent density and limits on internal defects (voids, shrinkage, cracks) and percentage of defective particles are required.
Chemical composition: Limits and reporting requirements for chemical constituents of chilled‑iron grit.
Sampling and testing: Sampling and test methods reference the ISO 11125 series (particle size distribution, hardness, density, defective particle count, foreign matter, moisture).
Designation and traceability: Mandatory product coding (e.g. “Abrasive ISO 11124 M/CI/G100”), package labelling and lot traceability for commercial units.
Scope limitation: Requirements apply only to abrasives supplied in the new (unused) condition - not during or after re‑use.

Applications and who uses this standard

EN ISO 11124-2:2018 is intended for:

Abrasive manufacturers and suppliers - to design, test, label and supply compliant chilled‑iron grit.
Coating specifiers, paint contractors and QA inspectors - to select appropriate abrasive grades for surface preparation and verify conformity.
Procurement and project engineers - to write purchase orders and ensure the correct product designation and traceability.
Asset owners and maintenance teams - where blast‑cleaning (static or site equipment) is used and facilities exist for recovery and re‑use of abrasives.

Chilled‑iron grit is commonly chosen when angular, high‑density metallic abrasive is needed and when abrasive recovery systems are in place.

Related standards

ISO 11125 series - test methods for metallic blast‑cleaning abrasives (Parts 1–7 cover sampling, particle size, hardness, density, defects, foreign matter, moisture)
ISO 8504‑2 - blast‑cleaning techniques for surface preparation
Other parts of the EN/ISO 11124 series (specifications for different metallic abrasives)

Note: EN ISO 11124‑2:2018 is a safety‑relevant document; users should follow appropriate safety and handling instructions for abrasive materials and blasting equipment.
