1.1 This guide provides recommended formats for the recording of thermal transmission test data for thermal insulation and similar materials for inclusion in computerized material property databases. From this information, the database designer is able to construct the database dictionary preparatory for development of a database schema.

1.2 This guide is applicable to thermal transmission test data obtained from standard test methods that cover planar and radial specimen geometries.

1.3 This guide is not intended for thermal transmission data obtained for thermal insulation assemblies or systems (that is, heat transmission coefficients for walls, roofs, ceilings, and floors).

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

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.

4.1 This guide defines the principal elements of information, which are considered important and worth recording and storing permanently in computerized databases. Sufficient information is provided in this guide to enable the user to construct a database structure suitable for the intended application involving thermal insulation. Guidance on the storage of (optional) digital images associated with test data is provided in Appendix X1.

4.2 Because of increased activity in building computerized materials databases and to maintain uniformity and ease of data comparison and interchange, these formats provide for the inclusion of specific elements of thermal transmission test data in databases.

4.3 The key benefit of using this guide is the establishment of a systematic approach to the management of thermal transmission test data. Other advantages include: (1) an increase in data accuracy because new test data are vetted in real time; (2) increased efficiency in data retrieval and storage; and, (3) improved data consistency. Over time, historical data can show important trends in the test measurements.

4.4 This guide has no implication on data required for materials production or purchase. Reporting of actual test results shall be as described in the actual materials specification or as agreed upon between the vendor and purchaser.

4.5 The suggested set of units for the recommended standard format given in this guide is SI. This guide, however, does not preclude other sets of units, such as inch-pound (IP).
