ISO 8502-6 Preparation of Steel Substrates Prior to Application of Paint and Related Products - Extraction of Soluble Contaminants for Analysis

EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of ISO 8502-6 testing. ISO 8502-6 describes a method for removing soluble contaminants from a surface for analysis using flexible cells in the form of adhesive patches that can be attached to any surface regardless of its shape (flat or curved) and shape.

The described method is suitable for use in the field to determine the presence of soluble contaminants prior to painting or a similar process. This part of ISO 8502 does not cover subsequent analysis of dissolved contaminants. Analysis methods suitable for field use are described in other parts of ISO 8502.

This standard is one of many parts of ISO 8502, which specifies tests for assessing surface cleanliness. Regarding this type of testing, there are various methods for analyzing and removing soluble contaminants from surfaces to be painted. One of these methods is based on taking relatively large test surfaces. This technique provides average values ​​of current pollution but can obscure localized concentrations of pollutants. Additionally, swabbing may not provide sufficient penetration to dissolve all deeper contamination such as iron salts.

However, there are other methods that use small cells for the liquid used to remove and collect surface contaminants. Cells attach to test surfaces where soluble contaminants might be expected; The place where pitting occurs and the extraction solution are prevented from being lost to evaporation. This closed cell technique generally provides more accurate point values ​​of the contamination present.
