ASTM C795 Standard Specification for Thermal Insulation for Use in Contact with Austenitic Stainless Steel
ASTM C795 与奥氏体不锈钢接触用绝热材料标准规范

This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. The material shall conform to the established requirements of the basic material specification. The physical and chemical requirements shall conform to the requirements of the basic material specification. Preproduction corrosion test and chemical analysis shall be performed to conform to the specified requirements.
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 non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. In addition to meeting the requirements specified in their individual material specifications, issued under the jurisdiction of ASTM Committee C16, these insulations must pass the preproduction test requirements of Test Method C 692, for stress corrosion effects on austenitic stainless steel, and the confirming quality control, chemical requirements, when tested in accordance with the Test Methods C 871.
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 and health practices and determine the applicability of regulatory limitations prior to use.
