DIN EN ISO 8502-2 PDF Download

The DIN EN ISO 8502-2 standard provides guidelines for assessing the cleanliness of steel surfaces prior to the application of paints or other coatings. Specifically, this standard addresses the laboratory determination of chloride ions on cleaned surfaces. The method outlined in the standard is applicable for assessing chloride-containing salts that are soluble in water and are present on steel surfaces, including those that have been previously coated.

It is important to note that this standard only provides guidance for laboratory testing of surface cleanliness, using washings from surfaces sampled on site. The method can be used to assess salts that have been introduced during the cleaning process or that have deposited on the surface before or after cleaning. This standard is intended to help ensure that steel surfaces are sufficiently clean and free from contaminants to ensure proper adhesion of paint or other coatings.
