【国外标准】 Standard Practice for Calibration of the Heat Flow Meter Apparatus (Withdrawn 2002)

1.1 This practice covers a means for calibration of the heat flow meter apparatus in conjunction with Test Method C518. The apparatus shall be calibrated as a unit, with the heat flux transducer(s) installed in the apparatus using either standard reference materials (SRM), calibrated transfer specimens (CTS), or other appropriate reference standards. 1.2 This practice applies to the calibration of a heat flow meter apparatus over a wide range of heat flow rates and temperatures that permits the testing of a wide variety of insulation materials over an extended temperature range. It is applicable to materials with the same requirements and temperature ranges allowed in Test Method C518. 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.
