ASTM WK70310

    New Practice for Using the Heat Flow Meter Apparatus to Measure the Steady-State Thermal Transmission Properties of Specimens Smaller than the Metering Area

    (What is a Work Item?)

    Developed by Subcommittee: C16.30 | Committee C16 | Contact Staff Manager



    WK70310

    1. Scope

    1.1 This practice covers the measurement of steady state thermal transmission through small flat slab insulation specimens using a heat flow meter apparatus. For the purpose of this practice, small is defined as a specimen with dimensions less than the size of the heat flux transducer that is being used to measure the heat flow. 1.2 This practice outlines additional requirements and considerations when one attempts to use Test Method C518 to test a specimen that is smaller than the apparatus heat flux transducer area. 1.3 Units---The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all 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.
