Summary of this proficiency test:

On 27 July 2016, the proficiency test on SCCP/MCCP in Polymer (iis16P06) was finished. It started on 20 April 2016 (see message ′proficiency Test on SCCP/MCCP in Polymer started′ on this website) when the samples were distributed. On 9 September 2016 an addendum report was published.

In this international interlaboratory study 57 participants in 21 different countries have participated.

The participants were requested to determine MCCP and SCCP.

The proficiency test report summarises per test, the test results, the analytical methods reported by the participants and the z-scores calculated by iis 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. For each test a comparison is made between the results of the group of participants and the requirements given by the relevant standard (e.g. ISO, DIN, ASTM) when applicable.
