Water quality — Sampling — Part 1: Guidance on the design of sampling programmes and sampling techniques

This document sets out the general principles for, and provides guidance on, the design of sampling programmes and sampling techniques for all aspects of sampling of water (including waste waters, sludges, effluents, suspended solids and sediments). This document does not include detailed instructions for specific sampling situations, which are covered in various other parts of the ISO 5667 series and in ISO 19458.

Qualité de l'eau — Échantillonnage — Partie 1: Recommandations relatives à la conception des programmes et des techniques d’échantillonnage

Le présent document énonce les principes généraux et fournit des recommandations relatives à la conception des programmes et des techniques d’échantillonnage, en tenant compte de tous les aspects relatifs à l’échantillonnage des eaux (y compris des eaux résiduaires, des boues, des effluents, des matières en suspension et des sédiments). Le présent document n’inclut pas de consignes détaillées pour les cas d’échantillonnages spécifiques, qui sont couverts par différentes autres parties de la série ISO 5667 et par l’ISO 19458.
