Scope

This verification system table is applicable to the verification and value transmission of pendulum impact energy (Xia-type) measuring instruments in the range of 15 to 300 J. It specifies the use, composition, and main metrological parameters of the impact energy national standard, as well as the value transmission process from the national standard to working measuring instruments through metrological standards, and indicates their errors and basic verification methods.
In the entire verification system table, impact energy measuring instruments are divided into two categories: the first category is fixed measuring instruments that generate (or reproduce) impact energy, and the second category is portable standard impact blocks that transmit impact energy.
