ASTM C647-08

Standard Guide to Properties and Tests of Mastics and Coating Finishes for Thermal Insulation

SIGNIFICANCE AND USE
Each of the properties listed should be considered in selecting materials for specific projects. A list of the selected properties with limiting values assigned will form a part of the product specification.  
All of the properties may not be pertinent in any specific situation, and all of the tests outlined may not be required. A condition to any specification must be an evaluation of the proposed use to determine which properties may be required.
Membrane reinforcements are frequently specified and used with mastics and coatings. Service properties of such systems of finishes may be different from the unreinforced finishes; therefore, it is essential to test specimens of the reinforced system.
SCOPE
1.1 This guide identifies properties of mastics and coating finishes characterizing their performance as finishes for thermal insulation.
1.2 These properties relate to application and service. Each property is defined, and its significance and suggested test methods are described.
1.3 The properties appear in the following order in this guide.

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.
