An intercomparison of heat flow meter apparatus within the United Kingdom and Eire
David R Salmon, Ronald P Tye
The heat flow meter (HFM) technique is widely used for rapid and reliable measurement of apparent thermal conductivity of thermal insulation materials. In the British Isles there is a large number of HFM apparatus of different sizes and forms, mainly in the quality assurance and research laboratories of thermal insulation manufacturers. With the advent of European legislation requiring manufacturers to declare thermal performance values of their products, the National Physical Laboratory organised an intercomparison to assess the comparability and accuracy of industrial HFM measurements in the UK and Eire with the aim of helping to establish consistent measurements.
