Full title and description

Preparation of steel substrates before application of paints and related products — Specifications for metallic blast‑cleaning abrasives — Part 1: General introduction and classification. This part defines a classification system and the information required for the complete designation of metallic blast‑cleaning abrasives supplied in the new (unused) condition, intended for preparing steel substrates prior to coating application.

Abstract

This document describes a classification of metallic blast‑cleaning abrasives and specifies the characteristics required for their complete designation (for example, type, size/particle distribution, hardness, density and other defining properties). It applies only to abrasives supplied in the new/unused condition and does not cover abrasives during or after use; techniques for blast‑cleaning are referenced (see ISO 8504‑2).

Scope

ISO 11124‑1:2018 specifies a general introduction and classification system for metallic blast‑cleaning abrasives used to prepare steel substrates before application of paints and related products. The standard applies to abrasives supplied in the new (unused) state only and does not apply to abrasives during or after use. The properties and designation parameters identified are intended for use when preparing steelwork but are generally appropriate for other materials prepared by blast‑cleaning techniques (see ISO 8504‑2 for blasting methods).

Key topics and requirements

• Classification system for metallic blast‑cleaning abrasives (types and general categories such as shot, grit, chilled‑iron, cut wire, etc.).
• Specification of designation information required for complete product identification (e.g., material type, shape, size/particle distribution, hardness, apparent density, magnetic properties, permitted defects and chemical limits).
• Applicability limited to new (unused) abrasives; excludes in‑service or spent abrasives.
• Cross‑references to the ISO 11125 test methods series for sampling and laboratory test procedures used to verify abrasive properties.
• Guidance that the characteristics specified are suitable for steelwork preparation and generally appropriate for other substrates prepared by blast‑cleaning.

Typical use and users

Used by abrasive manufacturers and suppliers (to describe and certify product grades), specifiers and purchasers (to select appropriate abrasives for coating preparation), coating contractors and blast‑cleaning operators (for procurement and process control), inspection and testing laboratories (to verify conformity), and standards/quality managers involved in surface preparation for protective coatings.

Related standards

ISO 11124 is a multi‑part series; related parts specify requirements for particular metallic abrasive types (for example ISO 11124‑2: chilled‑iron grit, ISO 11124‑3: high‑carbon cast‑steel shot and grit, ISO 11124‑4: low‑carbon cast‑steel shot, ISO 11124‑5: cut steel wire, etc.). The ISO 11125 series contains test methods for metallic blast‑cleaning abrasives (sampling, particle size distribution, hardness, microstructure and defective particles, etc.). For blast‑cleaning techniques and surface preparation methods, see ISO 8504‑2 and related ISO 8501 series.

FAQ

Q: What is this standard?

A: ISO 11124‑1:2018 is the first part of the ISO 11124 series; it provides a general introduction and a classification scheme for metallic blast‑cleaning abrasives used to prepare steel substrates before painting or coating.

Q: What does it cover?

A: It covers the classification and the required designation information for metallic abrasives supplied in the new/unused condition (properties such as type, size range, hardness, density and allowable defects) and notes applicability to steelwork and other substrates prepared by blast‑cleaning; it does not include test methods (these are in ISO 11125) or in‑service abrasives.

Q: Who typically uses it?

A: Manufacturers and suppliers of metallic abrasives, coating contractors, specifiers, inspection and test laboratories, procurement and quality personnel involved in surface preparation and protective coatings projects.

Q: Is it current or superseded?

A: ISO 11124‑1:2018 is published and in force (published August 2018). ISO has indicated a revision process (a DIS for a new edition has been issued), so users should check for a published replacement or confirm the current status with their national standards body before relying on the text for procurement or certification.

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 11124 series (other parts address specific abrasive types) and is used together with the ISO 11125 series of test‑method standards and standards on blasting techniques such as ISO 8504‑2.

Q: What are the key keywords?

A: metallic blast‑cleaning abrasives, classification, surface preparation, shot, grit, cut steel wire, new abrasives, abrasive designation, ISO 11125, ISO 8504.
