J. C. Torres-Guzmán, J. Aranzolo Suárez

Abstract

A proficiency test, PT, was performed in Mexico among pressure calibration laboratories. The proficiency test was carried out in negative pressure from -7 kPa to -70 kPa. The PT was promoted by the Mexican accreditation body (EMA). CENAM, the Mexican national metrology institute, was the pilot laboratory. In this proficiency test 18 laboratories participated. The results compatibility was analyzed by means of the normalized error equation and all laboratories obtain results within +1 and -1.
