ASTM C456-13

1.1 This test method covers measurement of the relative resistance of basic brick and shapes to hydration.

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

1.3 This standard does not purport to address all of the safety problems, 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.

2.1 This test method compares relative resistance to hydration of basic refractory brick and shapes in laboratory tests.

2.2 This test method allows an estimate to be made of the relative potential for hydration.

2.3 The test method is used in industry and in some cases it is used for specification purposes.

2.4 The results must be carefully used as a means of predicting whether or not basic brick or shapes will hydrate under actual conditions of storage or service.
