Abstract

The calibration measurement capability - CMC is defined as the smallest uncertainty that a 
laboratory can achieve within its powers when carried out more or less daily calibration of nearly 
ideal measurement standards intended to define, generate, keep or renew units of that size, or one or 
more of its value, or when carried out more or less daily calibration of nearly ideal measuring 
instruments designed for the measurement of its size. Estimation of calibration measurement 
capabilities of laboratories authorized for calibration, based on the method described in the 
document EA-4/02, and is confirmed by experiment 1. The authorized calibration laboratory CMC 
achieved in regular operation in accordance with its mandate. When displaying CMC laboratories 
covering measuring ranges of transmission standards have an impact on the CMC. Since in this paper 
covers two transmission standards, MGCplus-Z4/200 kN, calibrated measuring range from 20 kN to 
200 kN and the transmission standard MGCplus-Z4/500 kN, calibrated measuring range from 50 kN 
to 500 kN, determined by the CMC for measuring range from 20 kN to 500 kN.
