    Significance and Use

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

    3.2 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.

    3.3 The data from this test method are suitable for specification acceptance, estimating heat loss and surface temperature, and design of multi-layer refractory construction.

    3.4 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 to determine the thermal conductivity of refractory brick with the exception of insulating firebrick (use Test Method C182) and carbon refractories (use Test Method C767). This test method is designed for refractories having a conductivity factor of not more than 200 Btu·in./h·ft2·°F (28.8 W/m·K).

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
