Full title and description

STB DIN EN ISO 11125-9 E 2022-03 — Preparation of steel substrates before application of paints and related products — Test methods for metallic blast‑cleaning abrasives — Part 9: Wear testing and performance. This document specifies laboratory procedures to assess the service life (wear) and cleaning performance of virgin metallic blast‑cleaning abrasives, primarily using centrifugal blasting test methods.

Abstract

This standard defines three laboratory procedures for testing the service life (wear and consumption) of metallic blasting abrasives and additional procedures, performed on the same test equipment, to evaluate abrasive cleaning performance by transmitted kinetic energy. It applies to virgin metallic blasting media in the delivery state tested under centrifugal‑blasting laboratory conditions and is intended for comparison, quality inspection and quality control.

Scope

The standard applies to the laboratory testing of virgin metallic blasting abrasives in their delivery state using centrifugal blasting equipment. It specifies three wear‑testing procedures to determine service life and additional tests to evaluate cleaning performance (measured by kinetic energy transfer and cleaning efficiency). The results are intended for comparative testing, supplier quality inspection and process quality control; special arrangements may be needed for particular machine types or media.

Key topics and requirements

• Three defined laboratory procedures for abrasive wear (service life) testing under centrifugal blasting conditions.
• Methods to evaluate abrasive cleaning performance via transmission of kinetic energy to the substrate.
• Applicability limited to virgin metallic blast‑cleaning media in the delivery state; not intended for used/recycled media without specific arrangements.
• Use of results for comparison, quality inspection and monitoring (quality control) of abrasive supplies.
• Notes on special arrangements or machine-dependent adaptations where required by particular test rigs or media.

Typical use and users

Typical users include abrasive manufacturers, independent test laboratories, coating and surface‑preparation quality control teams, procurement/specification engineers and inspection authorities who need to compare abrasive types, verify supplier consistency, or validate abrasive performance for surface preparation prior to coating. The standard is used both for comparative product testing and for supplier quality control.

Related standards

Part 9 belongs to the ISO 11125 series (preparation of steel substrates — test methods for metallic blast‑cleaning abrasives). The DIN publisher recommends the EN ISO text as the current reference in lieu of some older national standards (for example as a replacement reference where DIN 50315:2010‑05 was withdrawn). Users should consider other parts of ISO 11125 and related surface‑preparation/coating standards when specifying tests.

FAQ

Q: What is this standard?

A: It is Part 9 of the ISO 11125 series — a test method standard that specifies laboratory procedures for measuring wear (service life) and performance of metallic blast‑cleaning abrasives, adopted as an EN/DIN national edition in 2022.

Q: What does it cover?

A: The standard covers three laboratory wear‑testing procedures for centrifugal blasting equipment and procedures to evaluate cleaning performance (kinetic‑energy transfer and cleaning efficiency) for virgin metallic abrasives in the delivery state; it is intended for comparative testing, inspection and monitoring.

Q: Who typically uses it?

A: Abrasive manufacturers, independent testing and QC laboratories, coating contractors, specification writers and inspection bodies use it to compare abrasive types, confirm supplier consistency and support quality control of abrasive supplies and surface‑preparation processes.

Q: Is it current or superseded?

A: The ISO original is ISO 11125‑9:2021 (published August 2021) and national EN/DIN adoptions were published in 2022 (DIN EN ISO 11125‑9 published September 2022). Some early catalog entries show an "E" edition dated March 2022; catalog records indicate such early entries were superseded by the later national adoption. Users should check the edition date on the copy they obtain to ensure they have the final adopted text.

Q: Is it part of a series?

A: Yes — it is Part 9 of the ISO 11125 series (Preparation of steel substrates before application of paints and related products — Test methods for metallic blast‑cleaning abrasives). Consult other parts of ISO 11125 for complementary test methods and requirements.

Q: What are the key keywords?
