标准简介
适用范围:
4.1 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.4.2 All of the properties are not required, and all of the tests outlined are not required. A condition to any specification must be an evaluation of the proposed use to determine which properties shall be required.4.3 Membrane reinforcements are frequently specified and used with mastics and coatings. Service properties of such systems of finishes are often different from the unreinforced finishes; therefore, it is essential to test specimens of the reinforced system.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.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
