ASTM C1676/C1676M-14

Standard Specification for Microporous Thermal Insulation

SCOPE
1.1 This specification covers the composition, physical properties, and product forms of microporous thermal insulation for use on surfaces at temperatures from 80°C [176°F] up to 1150°C [2102°F], unless otherwise agreed upon by the manufacturer and purchaser.  
1.2 This specification only covers microporous thermal insulation comprising compacted powder, fibers and opacifiers.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
