Abstract

This document describes a classification of 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 the preparation of steelwork, the properties specified are generally appropriate when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2 [7].

Overview

ISO 11124-1:2026 provides the general introduction and classification for metallic blast-cleaning abrasives used in the preparation of steel substrates before the application of paints and related products. Developed by the International Organization for Standardization (ISO), this standard establishes the basic terminology, classification criteria, and identification requirements essential for specifying new and unused metallic abrasives. The standard is particularly relevant for industries involved in steel surface preparation, ensuring consistent quality and performance in abrasive blasting operations.

Key Topics

  • Classification of metallic blast-cleaning abrasives: The document describes how metallic abrasives are classified by material type, initial particle shape, and particle size range.
  • Abrasive types: Common metallic abrasives include chilled iron, high-chrome white iron, high-carbon cast steel, low-carbon cast steel, cut steel wire, and varieties of stainless steel.
  • Designation system: Specifies a standardized product designation method that includes abrasive type, shape, grade (particle size), and hardness (if applicable) for clear identification and specification.
  • Particle shape and grades: Key particle shapes-shot, grit, cylindrical, and irregular-are defined, each influencing the resulting surface profile.
  • Package identification and lot traceability: The standard requires clear labeling of products with full designations, including traceability details for product batches, ensuring supply chain transparency.

Applications

  • Steel surface preparation: The primary application of ISO 11124-1:2026 is for the preparation of steel substrates prior to painting or coating. This ensures optimal adhesion and long-lasting protective finishes in sectors such as construction, shipbuilding, automotive, and heavy machinery.
  • Surface profile control: By standardizing abrasive types and particle shapes, the standard helps control the surface roughness and cleanliness, critical for coating performance.
  • Enhanced quality assurance: The clear classification and designation framework enable contractors, specifiers, and suppliers to accurately communicate requirements, reduce errors, and improve compliance in international projects.
  • Non-steel surfaces: Although designed for steel, the properties outlined in ISO 11124-1:2026 are also applicable when preparing other materials, using metallic blast-cleaning abrasives.

Related Standards

ISO 11124-1:2026 is part of a comprehensive series dedicated to surface preparation:

  • ISO 11124 (all parts): Specifications for metallic blast-cleaning abrasives.
  • ISO 11125 (all parts): Test methods for metallic blast-cleaning abrasives.
  • ISO 11126 (all parts): Specifications for non-metallic blast-cleaning abrasives.
  • ISO 11127 (all parts): Test methods for non-metallic blast-cleaning abrasives.
  • ISO 8501-1: Visual assessment of surface cleanliness.
  • ISO 8503-2: Surface roughness grading procedures.
  • ISO 8504-2: Surface preparation methods by abrasive blast-cleaning.

Practical Value

By adopting ISO 11124-1:2026, organizations benefit from harmonized terminology, consistent material quality, and efficient communications between stakeholders. The standard supports high-performance outcomes in painting and protective coating applications, contributing to extended service life and reduced maintenance for steel structures. Ensuring that all metallic abrasives used are correctly classified and identified at the point of purchase and during application is essential for maintaining international best practices in surface preparation.

Introduction

This document is one of a number of parts of ISO 11124 (all parts) specifying requirements for metallic
abrasives for blast-cleaning.
[2]
Test methods for metallic blast-cleaning abrasives are given in the various parts of ISO 11125 (all parts) .
The requirements for non-metallic abrasives commonly used for blast-cleaning are specified in the various
[3]
parts of ISO 11126 (all parts) . Test methods to be used to define these requirements are contained in the
[4]
various parts of ISO 11127 (all parts) .
Abrasive blast-cleaning techniques are widely used to clean and prepare surfaces. During the development
of a series of International Standards dealing with the preparation of steel substrates before application
of paints and related products, it was decided that a need existed for a series of International Standards
covering those blast-cleaning abrasives commonly used in preparation of steelwork.
The type of blast-cleaning abrasive used and its particle shape can significantly affect the surface appearance
[5]
and profile form of the treated surface. ISO 8501-1 provides informative photographic examples of the
change in appearance imparted to steel when blast-cleaned with different abrasive types.

Introduction
[1]
Le présent document constitue l'une des parties de la série ISO 11124 qui spécifie les exigences relatives
aux abrasifs métalliques destinés à la préparation par projection.
Les méthodes d'essai relatives aux abrasifs métalliques destinés à la préparation par projection sont données
[2]
dans les différentes parties de la série ISO 11125 .
Les exigences relatives aux abrasifs non métalliques couramment utilisés pour la préparation par projection
[3]
sont spécifiées dans les différentes parties de la série ISO 11126. Les méthodes d'essai servant à déterminer
[4]
ces exigences sont données dans les différentes parties de la série ISO 11127 .
Les techniques de préparation par projection d'abrasif sont largement utilisées pour nettoyer et préparer
des surfaces. Lors de l'élaboration d'une série de Normes internationales sur la préparation des subjectiles
d'acier avant application de peintures et produits assimilés, il a été constaté qu'il était nécessaire d'élaborer
une série de Normes internationales couvrant les abrasifs destinés à la préparation par projection
couramment utilisés dans la préparation des ouvrages en acier.
Le type d'abrasif utilisé et la forme des particules peuvent influer sensiblement sur l'aspect de surface et
[5]
le profil de la surface traitée. L'ISO 8501-1 fournit des exemples de clichés représentatifs du changement
d'aspect communiqué à l'acier décapé avec différents types d'abrasif.
[6]
L'ISO 8503-2 décrit l'évaluation de la rugosité de surface des subjectiles préparés, à l'aide de comparateurs.
Le Tableau 1 du présent document identifie le type de comparateur à utiliser avec chacun des abrasifs
destinés à la préparation par projection considérés.
