Overview
ISO 11125-7:2018 establishes a standardized test method for determining the free moisture content in metallic blast-cleaning abrasives used in the preparation of steel substrates before paint application. This international standard specifies measuring the moisture by recording the mass loss of the abrasive sample when heated at controlled conditions. It forms part of the ISO 11125 series, which covers sampling and testing methods for metallic abrasives, complementing the ISO 11124 series that details abrasive types and specifications.
Moisture content in metallic abrasives is a critical quality factor impacting the effectiveness and consistency of surface preparation. Excess moisture may lead to issues such as reduced abrasive performance, surface contamination, and corrosion risks on treated steel surfaces. ISO 11125-7:2018 provides a reliable laboratory procedure to ensure abrasives meet requisite moisture limits, supporting quality control and process optimization within industrial coating and surface treatment operations.
Key Topics
- Test Method Scope: Measurement of free moisture in metallic abrasives by determining mass loss on heating.
- Apparatus Required: Precision balance (accuracy to 0.01 g), oven maintained at 110 ± 5 °C, suitable heat-resistant container, and desiccator with a moisture indicator.
- Sampling Procedure: Representative abrasive samples should be selected and stored in sealed containers following ISO 11125-1 guidance.
- Test Procedure: Weigh the test portion before and after heating the abrasive sample to dryness in an oven for at least one hour; calculate moisture content as a percentage by mass.
- Result Expression: Moisture content is reported to the nearest 0.01%, with replicate tests performed to ensure accuracy within specified tolerance limits.
- Reporting Requirements: Test reports must include product identification, reference to ISO 11125-7:2018, test results, deviations (if any), test date, and tester’s name.
Applications
ISO 11125-7:2018 is essential for industries involved in:
- Steel Surface Preparation: Ensuring metallic abrasives used for blast-cleaning have acceptable moisture levels for optimal paint and coating adherence.
- Quality Control Laboratories: Routine testing of blast-cleaning abrasive batches to maintain compliance with international standards and customer requirements.
- Coating and Painting Operations: Preventing moisture-related defects during substrate preparation, which can compromise coating durability and corrosion protection.
- Abrasive Manufacturing: Verifying product moisture content prior to distribution to ensure product performance and consistency.
- Infrastructure and Shipbuilding: Maintaining standards for abrasive blasting materials critical to structural steel maintenance and protection.
