Scope

1.1 This practice covers standard mean temperatures for reporting thermal properties of thermal insulations, products, and materials, and of related systems and components, both insulated and uninsulated. 1.2 Thermal properties shall be determined as a function of temperature by standard test methods. (Test Methods C177, C201, C335/C335M, C518, C745, C1114, C1363, Guide C653, and Practice C687, all in combination with Practice C1045.) NOTE 1—Standard referenced materials are needed to span the temperature range of the tests. 1.3 This practice recommends standard conditions for use in testing and evaluating thermal properties as a function of temperature by standard test methods. 1.4 General applications of thermal insulations include: 1.4.1 Building envelopes, 1.4.2 Mechanical systems or processes, and 1.4.3 Building and industrial insulations. 1.5 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. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 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.
