This specification covers molded expanded perlite block, fittings, and pipe thermal insulation intended for use on surfaces with temperatures of certain range. The insulation shall not have visible defects that will adversely affect its service qualities. Different test methods shall be performed in order to determine the properties of the block, fitting, and pipe insulations: density, apparent thermal conductivity, linear shrinkage after heat soaking, flexural strength, compressive strength, weight loss by tumbling, moisture content, water absorption after heat aging, surface bearing characteristics, hot-surface performance, and stress corrosion cracking of austenitic stainless steel.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers molded expanded perlite block, fittings, and pipe thermal insulation intended for use on surfaces with temperatures between 80 to 1200°F (27 to 649°C).

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 When the installation or use of thermal insulation materials, accessories, and systems may pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the recommended use of the company's products and shall also recommend protective measures to be employed in their safe utilization. The following safety caveat applies only to the test methods portion of 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
