Full title and description

ISO/TS 13530:2009 — Water quality — Guidance on analytical quality control for chemical and physicochemical water analysis. This Technical Specification gives guidance on within‑laboratory and between‑laboratory quality control measures to help laboratories produce water‑analysis results with a known level of accuracy and reliability.

Abstract

Provides practical recommendations and principles for analytical quality control (QC) used in chemical and physico‑chemical water analysis. Topics include design and use of control samples, calibration and reference materials, control charts and statistical monitoring, interlaboratory comparisons and proficiency testing; sampling is only briefly considered. The document is applicable to the analysis of all types of waters but is not intended for sludges and sediments and does not cover biological or microbiological testing.

General information

• Status: Published (Technical Specification; confirmed as current in ISO systematic review).
• Publication date: 2 March 2009.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 13.060.45 (Examination of water in general).
• Edition / version: Edition 1 — ISO/TS 13530:2009.
• Number of pages: 39.

Scope

Guidance is provided for analytical quality control procedures that apply to chemical and physico‑chemical methods used to analyse waters (including surface waters, groundwaters, drinking waters and wastewater). The TS focuses on producing results of known accuracy through within‑laboratory QC and between‑laboratory activities; it is not intended as guidance for sludge/sediment analysis and excludes biological or microbiological examinations. Sampling is acknowledged but only briefly addressed.

Key topics and requirements

• Within‑laboratory quality control: use of blanks, spikes, duplicates and control samples.
• Between‑laboratory quality assurance: interlaboratory comparisons and proficiency testing.
• Calibration and use of certified reference materials and standard solutions.
• Control charts and statistical process control for monitoring method performance.
• Assessment of method trueness, precision and measurement uncertainty.
• Documentation, corrective actions and reporting of QC results and limits.
• Recommendations on frequency of QC checks and acceptance criteria for routine analyses.

Typical use and users

Environmental and water‑testing laboratories, regulatory agencies, accreditation bodies, consultants and contract testing organisations use this TS to establish or improve routine analytical QC practices for chemical and physico‑chemical water analyses. It is also useful to laboratory quality managers, method developers and instrument suppliers who need to align processes with accepted QC principles.

Related standards

ISO/TS 13530:2009 replaces ISO/TR 13530:1997 as the updated guidance document. It is used alongside sampling standards in the ISO 5667 series and with measurement‑accuracy and interlaboratory guidance such as the ISO 5725 family and laboratory accreditation requirements (e.g., ISO/IEC 17025). Some parts of the ISO 5667 sampling series cite ISO/TS 13530 as a normative/reference document.

FAQ

Q: What is this standard?

A: ISO/TS 13530:2009 is a Technical Specification providing guidance on analytical quality control for chemical and physico‑chemical water analysis, aimed at producing results with known accuracy.

Q: What does it cover?

A: It covers within‑laboratory QC procedures (blanks, spikes, duplicates, control samples), statistical monitoring (control charts), use of reference materials and calibration, interlaboratory comparisons and proficiency testing; sampling is only briefly treated and biological testing is excluded.

Q: Who typically uses it?

A: Environmental and water‑analysis laboratories, accreditation assessors, regulators, consultants and instrument or reagent suppliers—anyone responsible for establishing or verifying analytical QC for chemical and physico‑chemical parameters in water.

Q: Is it current or superseded?

A: ISO/TS 13530:2009 is the published Technical Specification that superseded ISO/TR 13530:1997; the 2009 TS has been subject to ISO periodic review and is listed as confirmed/current in ISO records.

Q: Is it part of a series?

A: It is a stand‑alone Technical Specification in the water‑quality field but is commonly used together with related ISO families such as the ISO 5667 sampling series, the ISO 5725 accuracy series and standards for laboratory competence (ISO/IEC 17025).

Q: What are the key keywords?

A: Water quality; analytical quality control; calibration; reference material; control chart; proficiency testing; method validation; measurement uncertainty.
