Interlaboratory Proficiency Tests of the Quality Parameters of Fuels as an Effective Approach to Intralaboratory Inspection

  • Published:
Measurement Techniques Aims and scope

The many years of experience gained from the work of the Laboratory of Calorimetry of the Mendeleev All-Russia Research Institute of Metrology as a provider of interlaboratory proficiency tests of the quality parameters of coal and petroleum derivatives (residual fuel oil) is considered. A list of the inspection indicators of samples of coal and residual fuel oil is presented. A procedure for preparation and delivery of samples and a program for conducting tests are set forth, and an algorithm for statistical processing of the results of measurements obtained from participating laboratories is considered.
