Eurachem Working Groups

Eurachem Proficiency Testing Working Group

The Eurachem Proficiency Testing Working Group (PTWG) provides a forum within the European chemical community for pursuing excellence in the development and implementation of proficiency testing

Terms of Reference

  1. The Eurachem Proficiency Testing Working Group has been established and will operate in accordance with the Constitution agreed in the Eurachem Memorandum of Understanding.
  2. To improve the organisation of proficiency testing in Europe.
  3. To promote best practice in proficiency testing using appropriate mechanisms such as publications, workshops etc.
  4. To provide a forum for organisers and users of proficiency testing schemes on issues affecting the practice of proficiency testing
  5. To organise, on a periodic basis, an International workshop on proficiency testing in analytical chemistry, microbiology and laboratory medicine.
  6. To provide input and comments from the chemical measurement community to the EA/Eurolab/Eurachem Working Group on Proficiency Testing in Accreditation (EEE-PT WG).
  7. To provide input and disseminate output between Eurachem and the EEE-PT WG.
  8. To collaborate and provide input on proficiency testing into other Eurachem working groups.
  9. To provide input into international activities related to proficiency testing.

 Current Activities

  • Organisation of the 10th International Workshop on Proficiency Testing in Analytical Chemistry, Microbiology and Laboratory Medicine.
  • Preparation and translation of a series of information leaflets regarding topics of interest to proficiency testing, to encourage good practice across Europe.
  • Production of guidance on the evaluation of qualitative results in PT schemes.

A key role of the PTWG is to discuss both input and outcomes of issues addressed at the EA/Eurolab/Eurachem Working Group on Proficiency Testing in Accreditation (EEE-PT WG). The EEE-PT WG discusses issues that go much wider than analytical chemistry, and it is the responsibility of the Eurachem representatives to ensure that any decisions and outputs of the WG take into account the needs of analytical chemistry. Current representatives of the PTWG who respresent Eurachem on the EEE-PT WG are Brian Brookman, Laura Ciaralli and Raquel Murtula. In addition Frank Baumeister  (Germany) and Coralie Leonard (Switzerland) are also Eurachem representatives.
