Abstract
Thermal property data have historically been used to compare the thermal performance of insulation systems. Accurate calculcation and presentation of those data is critical to not only the laboratory performing those tests and the final user of the results, but also to the developers of product and building design specifications. ASTM Practice for Calculation of thermal Transmission Properties under Steady-State Conditions (C1045) was developed as a means of standardizing the calculation and presentation of these results. across the many test methods within the C16 Thermal Insulation umbrella. In this paper, a brief history of the development of the practice through the current version is presented. A discussion of the current practice follows including an example of its ue and an outline of its use in product specifications.
