Refractory brick and shapes of different compositions exhibit unique permanent linear changes after heating or reheating. This test method provides a standard procedure for heating various classes of refractories with appropriate heating schedules.

Linear reheat changes obtained by this test method are suitable for use in research and development, also often used to establish written specifications between producers and consumers.

Care should be exercised in selecting samples that are representative of the product being tested and that the schedule selected is appropriate to the product.

1. Scope

1.1 This test method covers the determination of the permanent linear change of refractory brick when heated under prescribed conditions.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Note 1—Test methods incorporating additional provisions pertinent to specific refractory materials are given in the following Test Methods: C 179, C 210, and C 605.

1.3 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
