TC5 - Hardness Measurement - About

IMEKO TC5 has over 30 members from more than 20 countries.

IMEKO TC5 is concerned with organizing international symposia on new theoretical knowledge in the field of hardness testing with the presentation of papers, including also recently developed equipment.
Topics are the exchange of experience among members of the Committee to solve outstanding problems, transmitting the results to the interested organizations or experts in different countries. The activities include, if necessary, initiating or guiding metrological activities in international cooperation (e.g. hardness comparison), which can help to elaborate and revise international standard specifications.
