Historical (view previous versions of standard)
This test method covers the qualitative determination of the sulfide resistance of ceramic decorations on glass to assure the necessary durability of the decoration. The decorated ware should be representative of the lot, or run, and should be taken in accordance with the prescribed principles. The preparations of the test solution are presented in details. The procedures for testing the sulfide resistance of ceramic decorations on glass are presented. The decoration on the test specimen and reference standard are graded in accordance with one of the following visual test grades: grade V1, grade V2, grade V3, grade V4, and grade V5. If stain exists, the decoration on the test specimen and reference standard are graded in accordance with one of the following physical test grades: grade P1, grade P2, and grade P3.
