Significance and Use
This test method is used to estimate the application temperature limits of a refractory mortar and will establish its classification.
This test method will be regarded as a pass or fail test because the results are based on observations of whether the mortar flowed from the joints as a result of the heat treatment used.
Results obtained by this test method will not agree with those obtained in service when heating is done from only one side.
This test method is not applicable for testing nonaqueous mortars.
1.1 This test method covers the determination of refractoriness of all types of refractory mortar by heating a pier of brick laid up with the test mortar to learn whether the prescribed heat treatment causes the mortar to flow out of the joints.
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.
