Abstract

A torque proficiency test among accredited laboratories in Mexico was performed starting in January 2007. The main objectives of this exercise were to estimate the level of agreement for the dissemination of the quantity among laboratories and to evaluate the compatibility, including the uncertainty associated to its measurements, of the laboratories results with the set references values. The Centro Nacional de Metrologia, CENAM (Mexico) was the pilot laboratory and responsible for the coordination of this program. The maximum torque measurement for this proficiency test was 800 N·m. The torque standard TS used for the proficiency test was a torque wrench with a range up to 800 N·m. In this torque proficiency test 5 Mexican torque accredited laboratories participated. The results of the test showed good agreement among the laboratories and also with the reference values set by the national metrology institute (CENAM).
