Description (English):

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.

Abstract

Overview

EN ISO 11126-1:2025 - “Preparation of steel substrates before application of paints and related products - Specifications for non-metallic blast-cleaning abrasives - Part 1: General introduction and classification” - provides a standardized system to classify non-metallic blast‑cleaning abrasives used in preparing steel substrates. The document applies to abrasives supplied in the new/unused condition and defines the characteristics required for a complete product designation. It supersedes EN ISO 11126-1:2018 and is part of the ISO 11126 series.

Key topics

Scope and applicability
- Classification of non‑metallic abrasives for steel substrate preparation.
- Applies only to new/unused abrasives; not to abrasives during or after use.
Abrasive types and codes
- Identifies commonly used non‑metallic types and their abbreviated coding (e.g., N/OL - olivine, N/GA - almandite garnet, N/CS - coal furnace slag, N/FA - fused aluminium oxide, and various slag types).
Initial particle shape
- Defines particle-shape symbols: S (shot - round) and G (grit - angular).
Particle size ranges
- Requires classification of abrasives by particle size range (expressed in millimetres) to describe mixtures of differently sized particles.
Full product designation and marking
- Prescribes the format for ordering and identification, e.g.: Abrasive ISO 11126 N/CS/G 0,2–0,5 (type / shape / size range).
Interface with surface profile assessment
- Notes the relationship to ISO 8503-2 for selecting the appropriate comparator when assessing resultant surface roughness.

Applications

Standardizes selection and specification of non-metallic blast abrasives for:
- Surface preparation before painting, coating or related protective systems on steelwork.
- Procurement and contract documents where unambiguous abrasive identification is required.
- Quality control and inspection of incoming abrasive supplies.
Although developed for steel, the specified properties are generally appropriate when preparing other substrates using blast‑cleaning techniques (see ISO 8504-2 for methods).

Who uses this standard

Coating specifiers, surface‑preparation contractors, inspectors and QA/QC engineers.
Procurement officers and manufacturers/suppliers of blast‑cleaning abrasives.
Standards bodies and technical committees developing complementary specifications.

Related standards

ISO 11126 series (other parts specifying test requirements)
ISO 11127 (test methods for non‑metallic abrasives)
ISO 11124 / ISO 11125 (metallic abrasives and test methods)
ISO 8504-2 and ISO 8503-2 (blast‑cleaning techniques and surface roughness assessment)

Keywords: EN ISO 11126-1:2025, non-metallic blast-cleaning abrasives, steel substrate preparation, abrasive classification, particle shape, particle size, surface preparation standards.
