DIN EN ISO 5667-3 E 2011-01 PDF

Full title and description

STB DIN EN ISO 5667-3 E 2011-01 — titled (draft) "Water quality — Sampling — Part 3: Preservation and handling of water samples" — is an English-language draft/committee document circulated under the DIN/EN/ISO adoption process in January 2011. The record (STB prefix) is an entry/distribution title for that draft version while the original normative text is published by ISO and adopted nationally by bodies such as DIN/CEN.

Abstract

This document provides guidance on the preservation, handling, transport and storage of water samples intended for physicochemical, chemical, hydrobiological and microbiological analyses, and on measures to minimise changes in sample composition between collection and analysis. It excludes certain specialised sample types and methods (for example ecotoxicological assays, passive sampling and microplastics, which are covered in other parts of the ISO 5667 series).

General information

• Status: Draft / committee English version (E 2011-01) as recorded in national/distribution catalogues; the work has subsequently been updated in later ISO/DIN editions.
• Publication date: 2011-01 (designation in title indicates January 2011 draft circulation).
• Publisher: STB (catalogue/distributor record) — original standard published by ISO and adopted by national bodies such as DIN/CEN.
• ICS / categories: 13.060.45 (Examination of water in general).
• Edition / version: E 2011-01 (draft English version). Note: later formal editions include ISO 5667-3:2012, ISO 5667-3:2018 and ISO 5667-3:2024.
• Number of pages: Draft listing varies by distributor; published national/adopted editions have differed (examples: ~50 pages for ISO 5667-3:2012, ~64 pages for some national (DIN) versions, ~66 pages for ISO 5667-3:2024). Use the specific adopted edition for exact page count.

Scope

Gives general requirements and practical guidance for sampling, preservation, handling, transport and storage of water samples when on-site analysis is not possible and samples must be analysed in a laboratory. It applies to samples for physicochemical, chemical, hydrobiological and microbiological determinations and describes principles for choice of containers, use of preservatives, cooling/freezing, filtration or centrifugation, and validation of storage times. It does not cover ecotoxicological assays, some biological assays, passive sampling and microplastics sampling (these are addressed in other parts of the ISO 5667 series).

Key topics and requirements

• Principles of sample preservation: cooling, freezing, chemical preservatives and when each is appropriate.
• Selection, preparation and cleaning of sample containers and closures to avoid contamination.
• Techniques for sample handling: filling, headspace control, filtration, centrifugation and stabilization steps.
• Chain of custody, labelling, documentation and transport conditions to maintain sample integrity.
• Recommended maximum storage times and guidance on validation of storage stability.
• Exclusions and cross-references to related parts of ISO 5667 for specialised sampling (ecotoxicology, passive sampling, microplastics, sludges, etc.).

Typical use and users

Used by environmental monitoring and regulatory agencies, water and wastewater laboratories, consultancy firms, research institutes and utilities. Typical applications include field sampling programs, design of sampling procedures, specification of sample containers and preservatives, and preparation of sampling SOPs and chain-of-custody records for laboratory analysis.

FAQ

Q: What is this standard?

A: It is the (catalogue-listed) English draft titled STB DIN EN ISO 5667-3 E 2011-01 for "Water quality — Sampling — Part 3: Preservation and handling of water samples", a draft/committee English version circulated in January 2011 as part of the DIN/EN/ISO adoption process.

Q: What does it cover?

A: Guidance on preserving and handling collected water samples to ensure they remain representative for physicochemical, chemical, hydrobiological and microbiological analysis — including container selection, preservatives, cooling/freezing, filtration and documentation. It also identifies where other ISO 5667 parts apply (e.g., microplastics, ecotoxicology).

Q: Who typically uses it?

A: Environmental and public‑health laboratories, regulatory monitoring teams, water utilities, field sampling contractors, consultants and researchers involved in routine and compliance sampling programs.

Q: Is it current or superseded?

A: The 2011 E draft is a historical/committee-stage record; the formal international standard has been updated since then (ISO 5667-3:2012, ISO 5667-3:2018 and the currently published ISO 5667-3:2024). For compliance and up‑to‑date procedures use the most recent published/adopted edition (ISO 5667-3:2024 at the time of this product summary).

Q: Is it part of a series?

A: Yes — it is Part 3 of the ISO 5667 series on water sampling; other parts deal with sampling programme design, specific matrices (drinking water, sludges, sediments), biological tests, passive sampling and related topics. Consult the ISO 5667 series index for the complete list.

Q: What are the key keywords?

A: Water sampling; preservation; handling; transport; storage; preservatives; sample containers; chain of custody; ISO 5667 series; DIN EN ISO.
