Full title and description

Preparation of steel substrates before application of paints and related products — Test methods for metallic blast-cleaning abrasives — Part 9: Wear testing and performance (ISO 11125-9:2021). This part of ISO 11125 specifies laboratory procedures to evaluate the service life (wear) and cleaning performance of virgin metallic blasting abrasives under controlled centrifugal blasting conditions.

Abstract

This document specifies three procedures to test the service life of a blast‑cleaning abrasive under laboratory conditions and describes procedures to assess abrasive performance (cleaning ability) by measuring transmission of kinetic energy to the substrate. It applies to virgin metallic blasting media in the delivery state and uses centrifugal blasting test equipment to produce repeatable laboratory comparisons of wear and performance.

Scope

ISO 11125-9:2021 defines laboratory test procedures (three operational modes) for measuring abrasive wear (service life) and for evaluating abrasive cleaning performance by quantifying energy transfer to the substrate. The standard is intended for testing virgin metallic blast-cleaning abrasives in their delivery condition using centrifugal blasting machines in laboratory settings; it does not cover in‑service recycled abrasives or site‑scale performance directly, although laboratory results can be used to predict comparative behaviour.

Key topics and requirements

• Three specified laboratory test procedures for wear (service life) measurement of metallic blasting abrasives.
• Procedures to assess abrasive cleaning performance via kinetic-energy transfer to the substrate.
• Use of centrifugal blast‑testing machines and defined test parameters to ensure repeatability.
• Requirements for sample condition (virgin/new abrasives in delivery state), preparation and test reporting.
• Data and reporting elements that support comparative evaluation of different metallic abrasives (wear rates, mass loss, cleaning effectiveness metrics).

Typical use and users

Typical users include abrasive manufacturers (product development and QC), independent test laboratories, coating specifiers and procurement teams, surface‑preparation contractors, and standards/quality managers who need objective laboratory data to compare abrasive options and to write or verify technical specifications for blast‑cleaning operations.

Related standards

ISO 11125-9 is part of the ISO 11125 series of test methods for metallic blast‑cleaning abrasives (which complements the ISO 11124 product specification series). Related parts cover sampling and individual test methods such as sampling (ISO 11125-1:2018), particle size distribution (ISO 11125-2:2018), hardness (ISO 11125-3), apparent density (ISO 11125-4:2018) and determination of foreign matter (ISO 11125-6:2018). The ISO 11125-9 text has also been adopted as EN ISO 11125-9 in several regional bodies (published as an EN adoption in 2022).

FAQ

Q: What is this standard?

A: ISO 11125-9:2021 is an international test-method standard that specifies laboratory procedures to evaluate wear (service life) and performance of metallic blast‑cleaning abrasives using centrifugal blast testers.

Q: What does it cover?

A: It covers three laboratory procedures to measure abrasive wear and procedures to assess cleaning performance by measuring kinetic-energy transfer to the substrate. It applies to new (virgin) metallic blasting media in the delivery state tested under controlled centrifugal blasting conditions.

Q: Who typically uses it?

A: Abrasive manufacturers, independent testing laboratories, coating and surface-preparation specifiers, procurement and quality personnel, and contractors use the standard to compare abrasive products and to support specification or acceptance criteria.

Q: Is it current or superseded?

A: ISO 11125-9:2021 is published and current (edition 1, 2021). Regional adoptions (for example EN ISO 11125-9) were published in 2022; users should check national/regional catalogs for the latest adoption or confirmation status in their jurisdiction.

Q: Is it part of a series?

A: Yes — it is part of the ISO 11125 series of test methods for metallic blast‑cleaning abrasives and is intended to be used alongside other ISO 11125 parts and the product specification series ISO 11124.

Q: What are the key keywords?

A: Wear testing, abrasive performance, metallic blast-cleaning abrasives, centrifugal blasting, service life, cleaning performance, surface preparation, ISO 11125.
