significance And Use:

Unless there is a proper match between the expansions of the glaze and the body, all glazed whitewares may contain residual stresses from the firing that bonded the glaze to the body. In addition,... View More

scope:

1.1 This test method covers the determination of the resistance to crazing of fired, glazed, ceramic whitewares when stresses residual after glost firing may cause a tendency to craze, such stresses being induced by factors other than moisture expansion.

1.2 This test is not intended to induce moisture expansion, which fact should be kept in mind if the materials to be evaluated may exhibit moisture expansion. Note 1Test Method C 424 covers a method for determining resistance to crazing induced by moisture expansion. Its use is generally confined to testing nonvitreous and semivitreous ceramic whitewares because these products may be subject to such expansion. For whitewares with negligible moisture expansion (such as vitreous and impervious ware), the thermal shock method described herein is generally to be preferred.

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 a specific hazard statement, see Warning in .

1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.
