Standard Test Method for Sulfide Resistance of Ceramic Decorations on Glass

Fecha:
2019-02-05 /Active
Abstract:

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.

Scope:

1.1 This test method covers the qualitative determination of the sulfide resistance of ceramic decorations on glass to assure the necessary durability of the decoration.

1.2 This test method provides an indication of performance when and if the decorations are exposed to sulfide attack.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This test method generates hydrogen sulfide gas which is highly poisonous.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
