DESCRIPTION
This standard BS EN ISO 8502-9:2020 Preparation of steel substrates before application of paints and related products. Tests for the assessment of surface cleanliness is classified in these ICS categories:
  • 25.220.10 Surface preparation
  • 17.040.20 Properties of surfaces

This document specifies a field method for the assessment of the surface density of various water-soluble salts on steel surfaces, before and/or after surface preparation, by conductometric determination. The individual surface densities of the salt composition like chlorides, sulphates, sodium, etc, cannot be determined by this method.

This method assesses only contaminants that forms an electrolyte (ions) when in contact with water. These represent the greater part of the contaminants.
