    Significance and Use

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

    This procedure must be used with Test Method C201 and 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, estimating heat loss and surface temperature, and the design of multi-layer refractory construction.

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

    1. Scope

    1.1 This test method supplements Test Method C201, and shall be used in conjunction with that test method for determining the thermal conductivity of unfired monolithic refractories.

    1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory limitations prior to use.
