Summary of this proficiency test:

On 4 May 2016 the proficiency test on Biogasoline E85 started with 17 participants from 12 different countries.

On that date, the samples were dispatched to the laboratories. Enclosed to the samples were the instructions to the participants for this proficiency test and the material safety data sheet (MSDS).

The samples can be analyzed on: Acidity , Chloride, Copper Strip 3hrs @50°C, Density @ 15°C, Cu, Oxidation Stability, Oxygenates, Sulphur, Existent gum, Electric Conductivity @25°C, pHe , P, Sulphate and Water.

The deadline for reporting results is set on 10 June 2016. A laboratory that sends in results after deadline will definitely not get direct feedback in case any of its results are suspect! So be in good time to get the most out of this proficiency test.
