Overview

EN ISO 11127-6:2022 specifies a laboratory test method for determining water‑soluble contaminants in non‑metallic blast‑cleaning abrasives by conductivity measurement. Part of the ISO 11127 series of test methods for non‑metallic abrasives, this standard supports surface preparation and coating quality control by quantifying soluble salts and contaminants that can affect coating performance on steel substrates.

Keywords: EN ISO 11127-6:2022, non‑metallic blast‑cleaning abrasives, water‑soluble contaminants, conductivity measurement, surface preparation, test methods.

Key topics and requirements

  • Scope: Method for measurement of water‑soluble contaminants in non‑metallic abrasives using conductivity (µS/cm).
  • Sampling: Representative sampling according to ISO 11127‑1 is required before testing.
  • Reagents and water quality: Use conductivity water of at least grade 2 purity (ISO 3696).
  • Apparatus:
    • Conductivity measuring bridge with temperature compensation (or measure at 20 °C).
    • Conductivity cell with known cell constant.
    • Analytical balance (0.1 g accuracy) and a 100 ml graduated cylinder (±0.5 ml).
  • Procedure (summary):
    • Weigh a test portion of (100 ± 0.1) g abrasive into a 250 ml flask.
    • Add (100 ± 1) ml conductivity water, shake 5 min, stand 1 h, shake again 5 min and allow to settle; filter if necessary.
    • Measure solution conductivity at 20 °C and apply the cell constant to calculate conductivity of the abrasive extract.
    • Perform duplicate determinations; repeat if results differ by more than 10% (relative).
  • Expression and reporting:
    • Report mean of two valid determinations to the nearest 10 µS/cm.
    • Test report must identify the product, reference EN ISO 11127‑6:2022, include results, test date, operator name, and note deviations or unusual observations.

Applications and users

EN ISO 11127‑6:2022 is used to:

  • Control quality of non‑metallic blast abrasives supplied for industrial surface preparation.
  • Verify that residual, water‑soluble contaminants (e.g., salts) are within acceptable limits to avoid coating adhesion issues and corrosion under coatings.
  • Support specification and acceptance testing in pre‑painting inspection regimes.

Typical users:

  • Coating and paint manufacturers
  • Quality control and testing laboratories
  • Abrasive manufacturers and suppliers
  • Surface preparation contractors and inspectors
  • Corrosion engineers and procurement/specification writers

Related standards

  • ISO 11127 series - Test methods for non‑metallic blast‑cleaning abrasives
  • ISO 11127‑1 - Sampling of abrasives
  • ISO 11126 series - Specifications for non‑metallic blast‑cleaning abrasives
  • ISO 3696 - Water for analytical laboratory use

EN ISO 11127‑6:2022 helps ensure reliable, repeatable measurement of water‑soluble contaminants so that abrasive selection and surface preparation practices support long‑term coating performance.
