Thermal Performance

Differential Scanning Calorimetry

NPL provides comprehensive, world-class facilities (a number being unique within the UK) for measuring thermal properties including: thermal conductivity, thermal diffusivity, heat capacity and thermal expansion. Measurements are available from sub-ambient to extremely high temperatures, under controlled atmospheres, for a wide range of materials.

NPL provides technical experts on thermal measurement to a wide range of CEN, ISO, CIPM and EURAMET Working Groups and has UKAS accreditation to ISO Guide 34 for the provision of reference materials and transfer standards used to calibrate commercial measurement apparatus. We are also a notified laboratory under the Construction Products Directive and can provide measurements suitable for certification of construction products.
