ASTM C533-17(2023) - 1.3.2023
 
1. Scope

1.1?This specification covers calcium silicate block and pipe thermal insulation for use on surfaces with temperatures between 80 and 1700?F (27 to 927?C), unless otherwise agreed upon between the manufacturer and the purchaser.

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?The following safety hazards caveat pertains only to the test method (Section 12) described in this specification: 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.
