ASTM C1130-07

Standard Practice for Calibrating Thin Heat Flux Transducers

SCOPE
1.1 This practice, in conjunction with Test Method C 177, C 518, C 1114, or C 1363, establishes an experimental procedure for determining the sensitivity of heat flux transducers that are relatively thin.
1.1.1 For the purpose of this standard, the thickness of the heat flux transducer shall be less than 30 % of the narrowest planar dimension of the heat flux transducer.
1.2 This practice discusses a method for determining the sensitivity of a heat flux transducer to one-dimensional heat flow normal to the surface and for determining the sensitivity of a heat flux transducer for an installed application.
1.3 This practice should be used in conjunction with Practice C 1046 when performing in-situ measurements of heat flux on opaque building components.
1.4 This practice is not intended to determine the sensitivity of heat flux transducers that are components of heat flow meter apparatus, as in Test Method C 518.
1.5 This practice is not intended to determine the sensitivity of heat flux transducers used for in-situ industrial applications that are covered in Practice C 1041.
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.
