This test method is useful in quantitatively rating or ranking both ramming and refractory plastics by their linear stability after heating.

This test method is also useful for determining whether a ramming or refractory plastic can be used in a specified application based on linear change criteria.

This test method excludes basic and carbon bearing materials.

This test method can produce data for the engineering and design of refractory installations. The linear change data can be used to determine the number of joints necessary to maintain integrity of ramming or refractory plastic in a large installation.

1. Scope

1.1 This test method covers the determination of the drying shrinkage and of the combined drying and linear change of refractory ramming mixes and plastics.

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.

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.
