Significance and Use | ||||
5.1 This test method is designed to measure and compare thermal properties of materials under controlled conditions and their ability to maintain required thermal conductance levels. |

1. Scope | ||||
1.1 This test method covers a steady-state technique for the determination of the thermal conductivity of carbon materials in thicknesses of less than 25 mm. The test method is useful for homogeneous materials having a thermal conductivity in the approximate range 1< λ < 30 W/(m·K), (thermal resistance in the range from 10 to 400 × 10−4 m2 ·K/W) over the approximate temperature range from 150 K to 600 K. It can be used outside these ranges with reduced accuracy for thicker specimens and for thermal conductivity values up to 60 W/(m·K). 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.
1.2 This 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. 1.3 The values stated in SI units are regarded as standard. 1.3.1 Exception—The values given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. |
