The Selection and use of Reference Materials (2002)

Contents

The aim of this paper is to provide a short, simple and user-friendly guide for laboratories, and accreditation and certification bodies. It employs mainly ISO and VIM definitions and provides references to other more comprehensive and expert texts. It is intended to provide help for the inexperienced rather than the expert and necessarily simplifies some topics. It includes discussion and clarification of some misunderstood issues. Although based on the requirements of chemical measurement, it is intended to be also of use in other areas of measurement.

Metrological Traceability in Chemical Measurement - 2nd Edition (2019)

Contents

TrcFig2ttl 366x215This Guide gives detailed guidance for the establishment of metrological traceability in quantitative chemical analysis, based on the definition in the international vocabulary of basic and general terms in metrology (VIM). Though it is aimed principally at testing and measurement laboratories carrying out chemical measurement, the principles are expected to apply from routine analysis to basic research. The document is intended to assist laboratories in meeting the requirements on traceability of results given in ISO/IEC 17025.

This second edition amends the Guide to reflect revised terminology introduced in the third edition of the International Vocabulary of Metrology (VIM). Detailed discussion of the VIM terminology can be found in the Eurachem Guide “Terminology in Analytical Measurement: Introduction to VIM 3”.

Terminology in Analytical Measurement: Introduction to VIM 3

Contents

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.

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.
