Summary of this proficiency test:

On 21 July 2014, the proficiency test on Turbine Oil iis14L02 was finished. It started on 16 April 2014 (see message "Proficiency Test on Turbine Oil started" on this website) when the samples were distributed.

In this interlaboratory study 30 laboratories in 20 countries have participated.

The participants were requested to determine Flash Point PMcc, Total acidity, Base Number, Acid Number, Color, Density @ 15C, Kinematic viscosity @40C and @100C, Calculating viscosity Index from Kin. Visco @40&100C, Level of contamination, Water by KF, Water Separability and Foaming Characteristics

The proficiency test report summarises per test, the test results, the analytical methods reported by the participants and the z-scores calculated for each participant are tabulated. Also, for each test, the calculated summary (e.g. mean, standard deviation and reproducibility) is given.

In the report also an evaluation of the test results is given. Problems encountered in the analyses are mentioned and - where possible - suggestions for quality improvement are formulated. For each test a comparison is made between the results of the group of participants and the requirements given by the relevant standard (e.g. ISO, ASTM).
