Summary of this proficiency test:

On 23 April 2015, the proficiency test on PAH in polymers (iis15P02) was finished. It started on 21 January 2015 (see message Proficiency Test on PAH in polymers started on this website) when the samples were distributed.

In this international interlaboratory study 84 participants in 22 different countries have participated.

The samples were tested on 16 different PAH: Acenaphthylene Acenaphthene, Fluorene, Phenanthrene, Anthracene, Fluoranthene, Pyrene, Benzo[a]anthracene, Chrysene, Benzo[b+j]fluoranthene, Benzo[k]fluoranthene, Benzo[e]pyrene, Benzo[a]pyrene, Indeno[123-cd]pyrene, Dibenzo[a,h]anthracene, Benzo[g,h,i]perylene.

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.
