Preparation of steel substrates before application of paints and related products -- Tests for the assessment of surface cleanliness -- Part 3: Assessment of dust on steel surfaces prepared for painting (pressure-sensitive tape method)
This standard has been revised by ISO 8502-3:2017.
Provides pictorial ratings for the assessment of the average quantity of dust as well as descriptive classes for the assessment of the average size of the dust particles. The method is based on pressing a pressure-sensitive adhesive tape on to the steel surface to be tested. It may be carried out as a "pass/fail" test by comparison with specific limits or by permanently recording the dust present on a surface by mounting the tapes used on tiles, cards or paper.
