SIST EN ISO 11125-9:2022 PDF

Overview

EN ISO 11125-9:2022 (ISO 11125-9:2021) specifies laboratory test methods for assessing the wear and performance of metallic blast-cleaning abrasives used in preparing steel substrates before application of paints and coatings. The standard defines three procedures to determine the service life (wear/consumption) of virgin metallic blasting media under centrifugal blasting laboratory conditions and includes complementary procedures to evaluate abrasive cleaning effectiveness by measuring transmitted kinetic energy to the substrate.

Key topics and requirements

• Scope: Applies to virgin metallic blasting media in the delivery state tested by centrifugal blasting in laboratory machines.
• Three wear-test procedures:
  • 100% breakdown method
  • Full wear test (100% replacement method)
  • Stabilized consumption test
• Transmitted energy tests: Methods to evaluate abrasive cleaning performance (e.g., transmitted energy at 100% replacement and at full saturation) using the same test machines.
• Test apparatus and parameters: Describes relevant testing machines, sample preparation, preliminary testing, and evaluation principles. Emphasizes that machine design and adjustable parameters affect comparability with field performance.
• Reporting and comparison: Procedures intended for quality inspection, quality control, and comparison of abrasive batches or products under controlled laboratory conditions.
• Normative references: Cross-references other parts of the ISO 11124 and ISO 11125 series and related standards (for example ISO 11124-3/4/5, ISO 11125-1 to -7, ISO 12944-4, ISO 565).

Applications

• Quality assessment of metallic blasting abrasives (shot, grit, cut wire, etc.) for manufacturing and supply control.
• Comparative evaluation of abrasive service life and cleaning efficiency for R&D, product development, and supplier qualification.
• Supporting specification and procurement decisions for abrasive media used in surface preparation prior to painting and corrosion protection.
• Useful for blast equipment manufacturers, test laboratories, coating specifiers, corrosion engineers, steel fabricators, and QA/QC teams involved in surface preparation and protective coating systems.

Who should use this standard

• Abrasive manufacturers and suppliers
• Independent testing and certification laboratories
• Contractors and maintenance teams performing blast-cleaning
• Coating specifiers and corrosion protection engineers
• Procurement and quality managers responsible for abrasive performance and consistency
