A proficiency test is formed by a set of laboratories that must analyze several times a year, identical samples provided by the organizing entity. The Fuels Laboratory participate annually in international proficiency tests in order to:

  • Check the imprecision of the results obtained with the analytical methods used in the laboratory itself.
  • Compare the inaccuracy of the analytical methods themselves with those of other participants.
  • Support external quality control.
