1.1 This practice establishes an experimental procedure for determining the sensitivity of heat flux transducers (HFTs) that are relatively thin. The term sensitivity in this practice refers to the ratio of HFT electrical output to heat flux through the HFT.

1.1.1 For the purpose of this standard, the thickness of the HFT shall be less than 15 % of the narrowest planar dimension of the HFT.

1.2 This practice discusses two methods for determining HFT sensitivity. The first method is the calibration of the HFT in unperturbed heat flow normal to the surface of the HFT, while the second method is the sensitivity of the HFT in actual use, or the HFT conversion factor.

1.3 This practice should be used in conjunction with Practice C1041 when measuring in-situ heat flux and temperature on industrial insulation systems, and with Practice C1046 when performing in-situ measurements of heat flux on opaque building components.

1.4 This practice is not intended to determine the sensitivity of HFTs that are components of heat flow meter apparatus, as in Test Method C518. Refer to Practice C1132 for this purpose.

1.5 The following safety caveat pertains only to the Specimen Preparation and Procedure portions, Sections and , of this practice: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.
