Preparation of steel substrates before application of paints and related products -- Tests for the assessment of surface cleanliness -- Part 12: Field method for the titrimetric determination of water-soluble ferrous ions
ISO 8502:2003 describes a field method for the determination, by drop titration, of soluble ferrous ions on steel surfaces before and/or after surface preparation.
The method is intended mainly for use in the assessment of contaminants on a surface. It is easy for unskilled personnel to carry out and it is sufficiently accurate for most practical purposes.
