(Practice)Standard Practice for Mixing Thermal Insulating Cement Samples
Standard Practice for Mixing Thermal Insulating Cement Samples
SIGNIFICANCE AND USE
4.1 Insulating cement must be mixed with water and molded to prepare for testing.
SCOPE
1.1 This practice covers mixing thermal insulating cement samples with water in the preparation of specimens for use in all tests on the cement.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
