Preparation of steel substrates before application of paints and related products. Tests for the assessment of surface cleanliness - Extraction of soluble contaminants for analysis by acid extraction1 Scope This document specifies a method of extracting, for analysis, acid soluble contaminants from a surface by use of flexible cells in the form of adhesive patches or sleeves which can be attached to any surface, regardless of its shape (flat or curved) and its orientation (facing in any direction, including downwards). The described method is suitable for use in the field to determine the presence of acid soluble contaminants before painting or a
