Revision of C518-21 Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus


At the April 2022 TG meeting, concerns were brought to the TG that measurements are being performed using C518 where the calibration reference material has significantly different thermal conductance from the test material. The intended work item is to revise language in section(s) 1.2, 1.3, and possibly in Annex A, to put quantitative limits to the term "similar" used in section 1.2.
