Proficiency Testing Program for Mineral Analysis Laboratories
CCRMP operates the Proficiency Testing Program for Mineral Analysis Laboratories (PTP-MAL) in cooperation with the Task Group Laboratories Mineral Analysis Laboratories Working Group of the Standards Council of Canada (SCC). They are responsible for defining the metals of interest and the concentration range for each, as well as establishing the criteria and target values for assessing laboratory proficiency.
The proficiency testing program operates in full accord with ISO/IEC 17043 standard "Conformity Assessment –General requirements for proficiency testing" and CAN-P-1579, "Guidelines for the Accreditation of Mineral Analysis Testing Laboratories," striving in particular 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."
