What is Proficiency Testing?

External Quality Assessment for Your Laboratory

Proficiency Testing (PT) is an external quality assessment in which laboratories perform measurements or calibrations on the same or similar artefacts and compare their results with reference values and peer laboratories. For calibration laboratories, PT demonstrates technical competence and supports accreditation under ISO/IEC 17025.

ATRSPL designs and conducts PT rounds across mechanical, thermal, dimensional, mass, pressure, and related calibration disciplines, helping your laboratory identify bias, validate methods, and maintain measurement traceability.
