The paper describes the metrological activity in D.I. Mendeleev Institute for Metrology (St.-Petersburg, Russia) in the field of dilatometric research of solids. The main attention is paid to standard reference materials and standard samples of Thermal Expansion.

Measurements of linear thermal expansion coefficient (TEC) of a nanoporous metal carbide based carbon material were car-ried out. The values of linear thermal expansion coefficient in the range from 20°C to 300°C were obtained. The measured value of TEC are presented for this material for the first time.
