News items
October 2024 The protocol used by the Institute for Interlaboratory Studies (iis) to set up PTs has been updated in October 2024. The new version of the protocol can be downloaded here.
Sept. 2024 The new program for 2025 is now available.
We would like to invite you to register to our 2025 PTs via our Annual Program Page.

New PTs in the planned PT-scheme for Oil, Gas and Chemicals:
1. Sulfur iis25Y01, starting 19 March 2025 (final registration date is 7 March 2025).
2. UCOME iis25G03, starting 9 April 2025 (final registration date is 28 March 2025).
3. Chromium 6+ in Industrial (dried) Paint iis25Y02, starting 10 September 2025 (final registration date 29 August 2025).

New PT in the planned PT-scheme for Consumer Products:
3. Quinoline in Textile iis25T51, starting 9 April 2025 (final registration date is 28 March 2025).

May 2024 From the 1st of June 2024 the office opening hours of iis will be from Monday to Thursday from 7.00 to 16.30 hrs CET.
November 2023 Proficiency tests for the analysis of Methanol have been organized by the Institute for Interlaboratory Studies (iis) since 1999. The technical committee of IMPCA contacted the Institute for Interlaboratory Studies (iis) with the request to investigate the reproducibilities for Purity and Impurities using the test results of the iis PTs over the years.
Good estimations of the reproducibility have been obtained. For future PTs on Purity and Impurities in Methanol, iis will use these equations to estimate the target reproducibilities. Findings have been described in iis memo 2303. For the memo click here.
October 2023 Proficiency tests for the determination of Per- and Polyfluoroalkyl Substances (PFAS) in Polymer have been organized by the Institute for Interlaboratory Studies (iis) since 2011. Unfortunately, for the determination of PFAS in Polymers test method CEN/TS15968 does not mention reproducibility requirements. As alternative for the evaluation of the PFAS test results iis had used an estimated target reproducibility based on iis proficiency tests of 2016 and 2017. In 2023 iis decided to investigate the iis PT data gathered from 2011 to 2022 to estimate a more realistic target reproducibility for the determination of PFAS in Polymers. Furthermore, it was decided to use the same target reproducibility for all individual PFAS. Findings have been described in iis memo 2301. For the memo click here.
