Full title and description

St ISO TS 20612-2007 (Russian) — ISO/TS 20612:2007 "Water quality — Interlaboratory comparisons for proficiency testing of analytical chemistry laboratories". Technical specification that defines requirements and criteria for the planning, organisation, execution and evaluation of interlaboratory comparisons used as proficiency testing in the field of water, wastewater and sludge analysis. This entry refers to the ISO technical specification and a Russian-language edition/translation (designation "rus").

Abstract

ISO/TS 20612:2007 specifies criteria related to proficiency testing by interlaboratory comparisons for analytical chemistry laboratories working with water, wastewater and sludge. It addresses requirements for proficiency test providers and describes the design, conduct and statistical evaluation of proficiency tests. The specification is intended primarily for determinands that can be measured on a continuous scale (typically chemical and physicochemical parameters); it notes that continuity may not hold for some biological or microbiological determinands and provides guidance accordingly.

General information

• ICS / categories: 13.060.45 (Water quality).
• Edition / version: Edition 1 (ISO/TS 20612:2007).
• Number of pages: 25 pages.

Scope

This Technical Specification gives requirements for interlaboratory comparisons used as proficiency testing for analytical chemistry laboratories analysing water, wastewater and sludge. It covers the responsibilities of proficiency test providers, the design of comparisons (including selection and preparation of test material), homogeneity and stability assessment, statistical treatment and evaluation of results, reporting and the handling of non-conforming performance. The document is applicable where the measurand can be represented on a continuous scale (for example chemical and many physicochemical determinands); it gives cautionary guidance where continuity is absent (e.g., some microbiological determinands).

Key topics and requirements

• Requirements for proficiency test providers (organisation, impartiality, confidentiality and competence).
• Design of interlaboratory comparisons (definition of objectives, selection of participants, selection and preparation of test items).
• Assessment of sample homogeneity and stability for the chosen determinands and matrices.
• Statistical methods for evaluation of participant results and assignment of proficiency scores.
• Reporting requirements: content, format, interpretation of results and recommendations.
• Handling of outliers, corrective actions and follow-up to unsatisfactory performance.
• Limitations and special considerations for microbiological and other non-continuous determinands.

Typical use and users

Used by proficiency testing providers, environmental and water-analysis laboratories, accreditation bodies, laboratory quality managers, regulatory agencies and organisations responsible for laboratory competence and quality assurance. Typical applications include routine proficiency testing programmes for water and wastewater laboratories, pre-accreditation checks, and interlaboratory studies to validate methods and assess analytical performance.

Related standards

Relevant and commonly referenced standards include ISO/IEC 17043 (Conformity assessment — General requirements for proficiency testing), ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories), ISO 13528 (Statistical methods for proficiency testing by interlaboratory comparison), ISO 5725 (Accuracy — Trueness and precision of measurement methods and results), and the ISO 5667 series (water sampling standards). These standards are typically used together with ISO/TS 20612 when establishing and evaluating proficiency testing schemes for water analysis.

FAQ

Q: What is this standard?

A: ISO/TS 20612:2007 is a Technical Specification that sets out requirements and guidance for conducting interlaboratory comparisons used as proficiency testing for analytical chemistry laboratories analysing water, wastewater and sludge. The "St. . rus" listing indicates a Russian-language edition or translation of the ISO technical specification.

Q: What does it cover?

A: It covers the responsibilities of proficiency test providers, design and preparation of test materials, assessment of homogeneity and stability, statistical evaluation of results, reporting, and recommended follow-up actions. It focuses on determinands measurable on a continuous scale and provides caveats for biological/microbiological parameters.

Q: Who typically uses it?

A: Proficiency test providers, environmental and water laboratories, laboratory quality managers, accreditation bodies and regulators use this specification to design, run and evaluate proficiency testing schemes and to support laboratory accreditation and quality assurance.

Q: Is it current or superseded?

A: ISO/TS 20612:2007 is the 2007 Technical Specification (Edition 1). Users should check with national standards bodies or ISO for the latest status or any subsequent revisions, confirmations or withdrawals. (Published December 2007.)

Q: Is it part of a series?

A: It is a stand-alone Technical Specification but is commonly used alongside related ISO standards such as ISO/IEC 17043, ISO/IEC 17025, ISO 13528, ISO 5725 and the ISO 5667 series for sampling — together these form the normative framework for proficiency testing, laboratory competence and water quality analysis.
