Abstract

During a period where both North American and International product markets are opening, the issue of calibration traceability has become a sig mficant issue in the calibration of heat flow meters [1,2] used in thermal conductivity measurements on insulation materials. This paper will discuss the approach of the Production Support Services Laboratory of Owens Corning/Fiberglas Canada Inc. in addressing traceability to U.S., Canadian and International standards orgamza tions.

As a wide range of insulation products with varying thickness, density and R- values are tested in this laboratory, the calibration requirements may become quite elaborate. Included in this paper will be a techmcal discussion of the calibration stud ies and their findings performed on two different designs of heat flow meter appara tus. The calibration discussion is limited to a narrow temperature range typically used in the evaluation of insulation products to standard specifications.
