General Information

Overview
ISO 11127-6:2022 is an international standard specifying the method for determining water-soluble contaminants in non-metallic blast-cleaning abrasives by using conductivity measurement. This standard is part six of the ISO 11127 series, all of which focus on sampling and testing non-metallic abrasives used in blast-cleaning processes that prepare steel substrates before the application of paints and related coatings.
Developed by ISO Technical Committee ISO/TC 35 Paints and Varnishes in cooperation with CEN, this standard ensures a consistent approach for identifying contaminants that may impact the quality and performance of abrasive materials in surface preparation. It replaces the earlier 2011 edition with updated procedures and apparatus specifications.
Key Topics
Water-Soluble Contaminants Detection
The standard outlines a laboratory test to measure contaminants soluble in water found in abrasives through conductivity measurement at 20 °C, which reflects the presence of ionic substances affecting the cleaning and coating processes.Sampling and Preparation
Samples must be representative of the abrasive product, collected per ISO 11127-1. The test involves weighing a precise amount of abrasive, mixing with conductivity water (meeting ISO 3696 purity), shaking, settling, and filtering to prepare the solution for measurement.Measurement Equipment
Required apparatus includes a conductivity-measuring bridge with temperature compensation or measurement at 20 °C, a conductivity cell, a precise balance, and a graduated cylinder for accurate reagent volumes.Test Procedure and Results Expression
Conductivity is measured in microsiemens per centimeter (µS/cm). The test is performed in duplicate, with acceptance criteria ensuring less than 10% deviation between results. The mean conductivity value is calculated and reported, indicating contamination levels.Test Reporting Requirements
Thorough documentation is mandated, including product identification (aligned with ISO 11126 series), reference to ISO 11127-6:2022, test outcomes, deviations from the method, observations, test date, and operator name.
Applications
Surface Preparation Quality Control
Organizations involved in steel substrate preparation for protective coatings use this standard to verify the cleanliness of blast-cleaning abrasives, ensuring the removal of corrosive or interfering contaminants.Abrasive Supplier Certification
Producers and suppliers of non-metallic blast abrasives can apply ISO 11127-6:2022 testing to confirm their products meet industry requirements for water-soluble contaminants, improving material reliability.Coating Performance Optimization
By controlling abrasive contamination, coating adhesion and durability are enhanced, reducing maintenance, corrosion risks, and associated lifecycle costs.Regulatory and Contractual Compliance
This standardized testing supports compliance with client specifications and national or international standards that reference ISO 11127 series for surface cleaning and abrasive quality.
Related Standards
