Force Measurement Standards Up to 1 MN and Above

   The use of force measurements standards ensures testing of load and force sensors designed for measuring and studying large loads in rocket science, nuclear power plant construction, and testing of structural materials. The article provides an overview of the State Primary Standard of force GET 32–2011 of the Russian Federation in the range up to 1 MN, and also analyzes international experience in the field of reproduction of the unit of force with a value above 1 MN. The range of reproduction and composition of loads of the deadweight machine EU-100 from the composition of the State Primary Standard of force GET 32–2011 of the Russian Federation, deadweight machine of the Physical-Technical Federal Institute (PTB, Germany), deadweight machine of the National Institute of Standards and Technologies, deadweight machine of the Fujian Institute for Metrology (FPIM, China) and the deadweight machine of the Korea Research Institute of Standards and Science (KRISS, Republic of Korea) were assessed. The article is of scientific and practical interest to specialists in the field of reproduction of the unit of force of large values. The generalized experience can become the basis  for research in the field of improving the standards of force. The review is also addressed to teachers and students of specialized disciplines of higher education.
