    Significance and Use

    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 before the materials suffer thermal degradation. Alternatively, it is possible to study the effect of compositional changes such as chemical reaction or aging (6). Short measurement times permit generation of large amounts of data with little effort. The line-source probe and the accompanying test specimen are small in size, making it possible to subject the sample to a wide range of test conditions. Because this test method does not contain a numerical precision and bias statement, it shall not be used as a referee test method in case of dispute.

    1. Scope

    1.1 This test method covers the determination of the thermal conductivity of plastics over a temperature range from 40 to 400°C. The thermal conductivity of materials in the range from 0.08 to 2.0 W/m.K can be measured covering thermoplastics, thermosets, and rubbers, filled and reinforced.

    1.2 The values stated in SI units shall be regarded as standard.

    1.3 This standard does not purport to address the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish proper safety and health practices and determine the applicability of regulatory limitations prior to use.

    Note 1—There is no known ISO equivalent to this test method.
