Organized and managed by proficiency test ILT – Interlaboratory Test are a fundamental tool of quality of testing and calibration laboratories, and are part of the evaluation process, to establish its jurisdiction as to grant or maintain their ISO 17025 accreditation.
Proficiency testing programs help calibration laboratories, test laboratories and Inspection bodies to improve service quality by testing key areas of their technical competence, such as human resources, equipment and working methods.
In this program (EQP) of the external assurance of the quality of the results, the laboratories that participate in the present exercise, compliance with the sections 7.7.1, 7.7.2 (b) and 7.7.3 of the ISO / IEC 17025:2017
The CTPS are applicable to consumer products, services and a combination of both. They can be used by bodies and associations which conduct comparative testing programmes.
Program customized for two laboratories. The participating laboratory defines the test method and matrix choice. In the Bilateral customized PT programs, the participants result (calibration laboratories, test laboratories and Inspection bodies), will be compared with the results of ILT reference laboratory.
As a tool for evaluating the performance of participants with respect to pre-established criteria, through interlaboratory comparisons.
