Overview

EN ISO 11125-7:2018 is a key international standard developed by CEN for the preparation of steel substrates before the application of paints and related products. This part of the ISO 11125 series specifies the test method for determining the free moisture content in metallic blast-cleaning abrasives. The moisture level is critically assessed by measuring the mass loss of the abrasive after heating, ensuring the abrasives meet quality and performance standards for surface preparation processes.

This standard forms part of a comprehensive set of test methods related to metallic abrasives used in blast-cleaning applications, harmonizing procedures to guarantee consistency, safety, and effectiveness in coating preparations on steel substrates.

Key Topics

• Scope and Purpose
  Defines a precise method for quantifying free moisture in metallic blast-cleaning abrasives by measuring mass lost on heating, enabling accurate control over abrasive properties.

• Test Methodology
  Involves sampling a representative portion of abrasive material, heating at a controlled temperature (110 ± 5 °C) for one hour, and measuring mass before and after heating to calculate moisture percentage.

• Apparatus Required

  • Accurate balance with 0.01 g precision
  • Oven maintained at 110 ± 5 °C
  • Heat-resistant container or tray
  • Desiccator with silica gel or desiccant material

• Sampling and Procedure
  Emphasizes representative sampling according to ISO 11125-1 and duplicate tests to ensure data reliability.

• Results Expression
  Moisture content is calculated as a percentage of mass lost relative to the original mass, with strict criteria for reproducibility between test duplicates.

• Documentation and Reporting
  Requires comprehensive test reporting including reference to ISO 11125-7:2018, sample identification, test results, date, deviations, and tester information.

Applications

• Surface Preparation for Coatings
  The standard is essential for preparing steel substrates ahead of painting and coating applications, ensuring abrasives are free from excess moisture which can impair surface cleanliness and coating adhesion.

• Quality Control in Abrasive Manufacturing
  Manufacturers of metallic blast-cleaning abrasives rely on this method to maintain consistent moisture levels, critical for product performance and compliance with international specifications.

• Industrial Coating Processes
  Industries including construction, shipbuilding, automotive, and heavy machinery use this standard to verify abrasives’ suitability, minimizing surface corrosion and ensuring optimal paint adhesion.

• Maintenance and Protective Coatings
  Proper moisture analysis helps prolong steel substrate longevity by enabling surface treatments that adhere correctly and provide durable protection against environmental factors.

Related Standards

EN ISO 11125-7:2018 is part of a coherent series of standards addressing metallic blast-cleaning abrasives, closely integrated with ISO 11124 specifications for different types of abrasives:

• ISO 11124 Series
  Specifies requirements for various metallic abrasives like chilled-iron grit, cast-steel shot, and cut steel wire abrasives.

• ISO 11125 Series
  Comprises test methods for abrasive sampling, particle size distribution, hardness, apparent density, defective particles, foreign matter, and wear testing.

• Key Parts in ISO 11125

  • Part 1: Sampling
  • Part 2: Particle size distribution
  • Part 3: Hardness determination
  • Part 4: Apparent density
  • Part 5: Defective particles and microstructure
  • Part 6: Foreign matter
  • Part 7: Moisture determination (this standard)
  • Part 9: Wear testing and performance (under preparation)

For full implementation and quality assurance in surface preparation, adherence to these interconnected standards is recommended.

---

By following the EN ISO 11125-7:2018 standard, professionals and manufacturers ensure that metallic blast-cleaning abrasives used in steel substrate preparation are tested accurately for moisture content. This enhances process reliability, coating durability, and overall surface protection in industrial painting and finishing workflows.
