Full Description

1.1This test method covers a steady-state technique for the determination of the thermal conductivity of carbon materials in thicknesses of less than 25mm. The test method is useful for homogeneous materials having a thermal conductivity in the approximate range 1 30 W/(mK), (thermal resistance in the range from 10 to 400 10⁴ m² K/W) over the approximate temperature range from 150K to 600K. It can be used outside these ranges with reduced accuracy for thicker specimens and for thermal conductivity values up to 60W/(mK).

Note 1:It is not recommended to test graphite cathode materials using this test method. Graphites usually have a very low thermal resistance, and the interfaces between the specimen to be tested and the instrument become more significant than the specimen itself.

1.2This test method is similar in concept to Test Methods E1530 and C518. Significant attention has been paid to ensure that the thermal resistance of contacting surfaces is minimized and reproducible.

1.3The values stated in SI units are regarded as standard.

1.3.1Exception-The values given in parentheses are for information only.

1.4This 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 and health practices and determine the applicability of regulatory limitations prior to use.
