Summary of this proficiency test:
On 11 March 2015 the proficiency test on Natural Gas started with 49 participants from 30 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 Methane, Ethane, Propane, n-Butane, iso-Butane, Carbon dioxide, Nitrogen, Caloric Value (sup), Density, Relative Density, Wobbe index.
The deadline for reporting results is set on 10 April 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.
