Proficiency Testing

Bibliography of Proficiency Testing and EQA publications (2007)

NOTE: This list is no longer  maintained and is held for historical reference only. The PT bibliography has been superseded by the Eurachem Reading List, which includes a section on proficiency testing

This list of publications concerning PT/EQA was compiled by the EURACHEM Proficiency Testing Working Group (EPTWG) to provide a listing of such publications in a single source. The document is not exhaustive. References from 1996-2006 are included and are listed alphabetically, by the first author, for each year.
