Proficiency Testing External Links


Our proficiency testing staff are involved in a number of external committees and working groups which have a remit to promote analytical quality through proficiency testing and by other means. These include:

Eurachem PT working group

The EURACHEM Proficiency Testing Working Group (PTWG) provides a forum within the European chemical measurement community for pursuing excellence in the development and implementation of proficiency testing. The terms of reference include

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

This working group, in association with others, has assisted in the production of the following Guide:

Selection, Use and Interpretation of Proficiency Testing (PT) Schemes by Laboratories (2nd edition, 2011)

This document represents the current state-of-the-art with respect to the selection and use of proficiency testing schemes, and the interpretation of results and evaluations given in proficiency testing schemes. Although this is aimed primarily at staff in analytical laboratories, it is also useful for customers of laboratories, assessors working for accreditation bodies and other external users of PT scheme results. This second edition, approved in 2011, has been prepared by the EEE-PT Working Group (EA-Eurolab-Eurachem). EQALM (European Organisation for External Quality Assurance Programmes in Laboratory Medicine) as an affiliate member was also involved in this revision

Eurachem has published a range of guides on quality and accreditation issues in analytical measurement.

Analytical Methods Committee, Royal Society of Chemistry

The Analytical Methods Committee (AMC) is the Committee of the Analytical Division Council that handles matters of technical importance to the members of the RSC Analytical Division and the analytical science community in general. The broad aim of the AMC is to participate in national and international efforts to establish a comprehensive framework for appropriate quality in chemical measurement, and to keep the analytical science community informed of developments. It achieves this aim through the activities of its expert sub-committees as well as the parent Committee, which fulfil the following functions:

  • development, revision and promulgation of validated, standardised and official methods of analysis

  • development and establishment of suitable performance criteria for methods and instruments

  • use and development of appropriate statistical methods

  • identification and promulgation of best analytical practice, including aspects relating to sampling, equipment, instrumentation and materials

  • generation of validated compositional data of natural products for interpretative purposes.

AMC has produced a number of technical briefs designed to bring up-to-date technical information on measurement science to members of the RSC Analytical Division and the wider analytical community. These can be accessed here.  A number of these briefs provide advice on various aspects of internal quality control and proficiency testing.

GESTIS Analytical Method Database

A useful analytical method information source is the GESTIS database.  This database contains a list of validated analytical procedures described as suitable for the analysis of chemical agents in air and draws upon methods developed both at an international (ISO) and at a national level (e.g. methods developed in  France (INRS), Germany (IFA), UK (HSL) and the USA (NIOSH/OSHA).
