Significance and Use
This test method is intended to be used when a quantitative measurement of the alkali durability of a ceramic-glass enamel is needed. The test is applicable to glass coated with fired enamels where exposure to strong alkalis, or alkalis at elevated temperatures might be encountered in service.
This test method is intended to be an accelerated, destructive test. Results can be used as an indicator of the relative durability of a particular enamel.
1.1 This test method covers the determination of the resistance of a fired ceramic-glass enamel to a 10 % alkali solution held near its boiling point for 2 h.
1.2 This test method is not applicable to large tempered glass sheets or specimens larger than 9 by 9 cm.
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9.
