Summary

Three methods for determining sheet steel surface cleanliness are described: 1) the “tape” test, 2) a hydrochloric acid swab/Leco 46 combustion method; and, 3) a direct oxidation/CO2 coulometer method. The first method is a qualitative test for surface cleanliness, whereas methods 2 and 3 measure surface cleanliness by quantifying the amount of surface carbon per unit surface area. Typical data obtained by these methods are illustrated, and the relative merits of each test are discussed.
