Summary of this proficiency test:

On 5 November 2014 the proficiency test on Transformer Oil (Fresh) started with 52 participants from 29 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, forms for the reporting of the analysis results and the material safety data sheet (MSDS).

The samples can be analyzed on: Density @ 20C, Di-electric dissipation Factor, Specific Resistance, Breakdown Voltage, Interfacial surface tension ,Flash Point, Kinematic Viscosity 40C,  Water, Acid number (neutralization number), and Furanic Compounds.

The deadline for reporting results is set on 5 December 2014. 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.

The test results can also be reported via our internet based "results reporting platform". A login and a password can be requested via email to
