Eurachem Guides

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

Eurachem guides are developed by the various working groups, often in collaboration with other organisations. Eurachem Members are free to translate guides into their own language, so many guides are available in several languages.

All Guides are currently available free of charge from the Eurachem Website. Many are additionally available in hard copy, either from the Secretariat or from other publishers.


Current Eurachem Guides

The current list of Eurachem Guides is as follows:

Quality assurance, accreditation and terminology

Proficiency testing

Measurement uncertainty and validation

Traceability and reference materials

Superseded Guides

Some Eurachem Guides have been superseded by the current editions listed above. Available electronic copies are listed in the Publication Archive.

Guide to Quality in Analytical Chemistry - 3rd edition (2016)


QAC 2016 cover 180hThe aim of this guide is to provide laboratories with guidance on best practice for the analytical operations they carry out. The guidance covers both qualitative and quantitative analysis carried out on a routine or non-routine basis. A separate guide covers research and development work (Quality Assurance for Research and Development and Non-routine Analysis,1998 ).

This third edition is a revision of the CITAC/Eurachem Guide published in 2002. The 2002 edition was developed from CITAC Guide 1 (which in turn was based on the Eurachem/WELAC Guide). The third edition reflects changes that were introduced with the publication of the 2005 version of ISO/IEC 17025. The terminology has also been updated to take account of ISO/IEC 17000:2004, ISO 9000:2015 and the 3rd edition of the International Vocabulary of Metrology – Basic and general concepts and associated terms (JCGM 200:2012 – VIM).

The Guide focuses on the requirements of ISO/IEC 17025, however the content should also be of use to organisations seeking accreditation or certification against the requirements of standards such as ISO 15189 or ISO 9001, or compliance with the Principles of Good Laboratory Practice

Quality Assurance for Research and Development and Non-routine Analysis (1998)


This guide, produced by a joint Eurachem/CITAC working party representing industrial, academic, and governmental interests, promotes and describes the concepts of quality assurance in the non-routine environment. The guide promotes a nested approach to quality assurance, dealing with it at a general organisational level, a technical level and a project specific level. It is intended to promote the use of QA as an effective tool for establishing and maintaining quality in R&D and non-routine operations. It does not seek to set criteria for accreditation of R&D although there is a section describing various methods for third party assessment of quality systems. The guidance may form the basis on which accreditation criteria can be set in the future. The guidance is intended to complement the existing CITAC guide (CG1) which describes QA in the routine environment. It is primarily directed towards analytical chemistry establishments but is, in principle, applicable to other sectors. An extensive bibliography is included.


The English language version (edition 1.0 1998) is available from the UK National Measurement System Chemical and Biological Metrology programme.

Accreditation for Microbiological Laboratories (2013)


80px-Anthrax cultureThis document has been produced primarily by an ad hoc Eurachem Working Group in collaboration with the EA (European co-operation for Accreditation) Laboratory Committee. It provides microbiological laboratories with appropriate information and guidance on how to fulfil the requirements of ISO/IEC 17025.

Note: The previous version of this guide was additionally approved as EA Guide EA 4/10 G:2002. For further information on the status of EA 4/10 G:2002 see the archive page of the 2002 Guide and the EA website.

Amendment (May 2014): The title page of the present website version (.P2) has been amended from the 2013 printing to remove an incorrect reference to EA 4/10.

Terminology in Analytical Measurement: Introduction to VIM 3


This guide has been produced by members of the Eurachem Education and Training Working Group and others co-opted to the Project group for this task.

In the world of metrology – the science of measurement and its application – there is a language which has to be learned. The International Vocabulary of Metrology (VIM) was produced to provide a common language, primarily for physical measurements. The third edition (International Vocabulary of Metrology – Basic and General Concepts and Associated Terms (VIM 3) was published in 2007. There are many differences between VIM 3 and earlier editions; one important change is captured in the title with the addition of the word ‘concepts’. The VIM 3 is a consistent set of concepts each described by a unique term, the ‘label’ of the concept. VIM 3 is applicable across all scientific disciplines thus making it relevant to those involved in performing measurements in chemistry and biology. Consistent definitions of concepts with their associated terms and symbols are essential if analysts and customers across the globe are to understand each other.

This Eurachem Guide discusses a selection of the concepts in VIM 3, focusing on those most likely to be encountered in analytical laboratories. It aims to cover chemical, biological and clinical measurements and gives examples over and above those in the notes accompanying the definitions in VIM 3. The guide is intended for laboratory staff, accreditation bodies, for those commissioning measurements and for those using measurement results. Lecturers and trainers may also find this guide useful when teaching aspects of metrology.
