Thermal Performance

Thermal performance data on materials and structures is required for design and heat management in most forms of advanced engineering and processing. NPL provides comprehensive, world class facilities (a number being unique within the UK) for measuring thermal properties including: thermal conductivity, thermal diffusivity, thermal transmittance, heat capacity and thermal expansion.

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.
