5.1 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.5.2 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 9.1.5 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.

3.1 The fineness of the frit has a direct bearing on many of its properties, such as fusibility, tearing, gloss, opacity, suspension in the slip, and ease of spraying.1.1 These test methods cover the determination of the fineness of frit in wet- or dry-milled porcelain enamels and other ceramic coatings for metals by means of the No. 200 (75-μm) or No. 325 (45-μm) sieve.1.2 The two methods appear as follows:  Sections    Method A—Referee Method   Method B—Routine Method  4 to 9 10 to 141.3 Method A is intended for use where a referee method of higher accuracy is required, while Method B is intended to meet the needs of normal enamel plant production control operations where a rapid, simplified method of sieve testing is required. The accuracy of the simplified method has proved to be entirely adequate for this use. The simplified test, however, is not recommended where high accuracy is required.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 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.

1.1 These definitions pertain to the terminology used in the porcelain enamel and ceramic-coated metal industries.1.2 Words adequately defined in standard dictionaries are not included. Included are words that are peculiar to these industries.1.3 Hyphenated words, double words, or phrases are listed alphabetically under the first word; additional important words are cross-referenced.1.4 When a word or phrase, listed as a synonym, is not separately defined, the defined word or phrase is the accepted or preferred form.1.5 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.
