Proficiency Testing Program for Mineral Analysis Laboratories
The Canadian Certified Reference Materials Project (CCRMP) operates the Proficiency Testing Program for Mineral Analysis Laboratories (PTP-MAL) since 1997.
The proficiency testing program operates in full accord with ISO/IEC 17043 standard “Conformity Assessment – General requirements for proficiency testing “and “SCC Requirements and Guidance for the Accreditation of Mineral Analysis Testing Laboratories”, to respond to the needs of Canadian mineral analysis laboratories.
PTP-MAL is a means by which a mineral analysis laboratory can assess its performance for one or more analytical methods independently of internal quality control. Moreover, participation in the program is obligatory if a laboratory is to be accredited or is to retain its accreditation for mineral analysis activities by SCC to ISO/IEC 17025 "General requirements for the competence of calibration and testing laboratories."
