Summary of this proficiency test:

On 7 October 2015 the proficiency test on Liquefied Propane  started with 47 participants from 27 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 safety data sheet (SDS).

The samples can be analyzed on: Ethane, Propane, Propylene, n-Butane, iso-Butane, n-Pentane, iso-Butene, 1-Butene, Molar Mass, Relative Density @60F and Vapour pressure @100F.

The deadline for reporting results is set on 13 November 2015. A laboratory that reports test 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 should be reported via our internet based "results reporting platform". A login and a password can be requested via email to
