1 GUIDELINES ON ANALYTICAL TERMINOLOGY ADOPTED BY THE CODEX ALIMENTARIUS COMMISSION, JULY 2009 INTRODUCTION The Codex Committee on Methods of Analysis and Sampling has agreed on Analytical Terminology for Codex Alimentarius and government use. A number of these terms were previously included in the Codex Procedural Manual. In most cases terms used in the Procedural Manual were adopted over time with an underlying hierarchy and can be traced verbatim to specific editions of ISO 3534, the GUM, the VIM, the IUPAC Orange Book or other international standards already adopted by Codex. Definitions of terms that have changed with newer editions of the international standards from which they were originally adopted have been updated preserving the original hierarchy found in the Procedural Manual. In cases where terms have been added in addition to those originally found in the procedural manual an effort has been made to preserve the conceptual continuity and relationship of the newer terms with extant ones. These terms, together with the terms which are included in specific International Protocols/Guidelines already adopted by Codex by reference are given below.

ANALYTICAL TERMS The following analytical terms are now defined by Codex for Codex purposes: • Accuracy • Analyte • Applicability • Bias • Calibration

• Certified reference material • Conventional quantity value • Critical value • Defining (Empirical) method of analysis • Error • Expanded measurement uncertainty • Fitness for purpose • HorRat • Inter-laboratory study • Laboratory performance (Proficiency) study • Limit of detection • Limit of quantification • Linearity • Material certification study • Measurand • Measurement method

• Measurement procedure • Measurement uncertainty • Method-performance study • Metrological Traceability • Outlier • Precision • Quality assurance • Rational method of analysis • Recovery/recovery factors • Reference material
