Proficiency Testing

Assuring the quality of Test Results implies that the laboratory have quality control procedures for monitoring the validity of tests undertaken. Among the quality control procedure, the inter-laboratory comparison or proficiency-testing programmes are considered  the best statistical techniques to determine the real capability and reliability of testing laboratories. In addition of being required by the ISO/IEC guides 25 and ISO/IEC 17025,  the CTL proficiency testing programme has received full support from the  IECEE Certification Management Committee for the purpose of increasing the "mutual confidence" between the CBTLs in the field of the CB Scheme and related recognition of CB Test Certificates.
