Significance and Use:

The thermal conductivity of refractories is a property required for selecting their thermal transmission characteristics. Users select refractories to provide specified conditions of heat loss and cold face temperature, without exceeding the temperature limitation of the refractory. This test method establishes the testing for thermal conductivity of refractories using the calorimeter.

This procedure requires a large thermal gradient and steady state conditions. The results are based upon a mean temperature.

The data from this test method are suitable for specification acceptance, and design of multi-layer refractory construction.

The use of these data requires consideration of the actual application environment and conditions.

Scope:

1.1 This test method covers the determination of the comparative thermal conductivity of refractories under standardized conditions of testing. This test method is designed for refractories having a conductivity factor of not more than 200 Btuin./hft2F (2818 W/mK), for a thickness of 1 in. (25 mm).

1.2 Detailed ASTM test methods to be used in conjunction with this procedure in testing specific types of refractory materials are as follows: Test Method C 182, Test Method C 202, Test Method C 417, and Test Method C 767.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided 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.
