(Test Method)Standard Test Method for Covering Capacity and Volume Change Upon Drying of Thermal Insulating Cement
Standard Test Method for Covering Capacity and Volume Change Upon Drying of Thermal Insulating Cement
SIGNIFICANCE AND USE
This test method is used to determine the wet covering and volume change upon drying of thermal insulating cement.
SCOPE
1.1 Wet covering capacity and volume change upon drying are often of major importance in the application of thermal insulating cement. These properties can be easily determined at the same time that the determinations of dry covering capacity are made. Therefore, the procedures for determining these three properties are covered together in this test method.
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 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.
1.4 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.
