Proficiency test according to ISO 17043

Interlaboratory comparisons may be used, for example, to:

  • determine the performance of individual laboratories for specific tests of measurements and to monitor laboratories´ continuing performance
  • identify problems in laboratories and initiate remedial actions which may be related to, for example, individual staff performance or calibration of instrumentation
  • establish the effectiveness and comparability of new test or measurement methods and similarly to monitor established method
  • provide additional confidence to laboratory clients
  • identify interlaboratory differences
  • determine the performance characteristics of a method – often known as collaborative trials
