Organization: ASTM International
Publication Date: 1 July 2026
Status: active
Page Count: 5
ICS Code (Thermoplastic materials): 83.080.20
significance And Use:

5.1 The relative simplicity of the test method makes it applicable for a wide range of materials (4, 5). The technique is capable of fast measurements, making it possible to take data... View More

scope:

1.1 This test method describes the determination of the thermal conductivity in the range from 0.08 W/m·K to 10.0 W/m·K of filled and unfilled thermoplastics, thermosets, and rubbers over a temperature range from -40?°C to 450?°C.

1.2 The SI units are the standard.

1.3 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.

1.4 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.
