ASTM C533-09

Standard Specification for Calcium Silicate Block and Pipe Thermal Insulation

ABSTRACT
This specification covers calcium silicate block and pipe thermal insulation for use on surfaces. Thermal insulation shall be of the following types: Type I; Type IA; and Type II. Calcium silicate thermal insulation shall consist principally of hydrous calcium silicate usually with the incorporation of fibrous reinforcement. The insulation shall conform to the physical requirements specified. Following test methods shall be performed: block insulation; pipe insulation; apparent thermal conductivity; linear shrinkage after heat soaking; flexural strength; compressive strength; mass loss by tumbling; hot surface performance; surface burning characteristics; stress corrosion performance; and moisture content by dry weight.
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 the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
