Water quality. Sampling - Guidance on the use of sampling data for decision making. Compliance with thresholds and classification systems Ingestion-build-232773 dimensions and provides reference standards1 Scope This part of ISO 5667 establishes principles, basic requirements, and illustrative methods for dealing with the use of sample data for decision making based on the assessment of the confidence that water quality: a) meets targets and complies with thresholds; b) has changed; and or c) lies in a particular grade in a classification system. This part of ISO 5667 also specifies methods for preliminary examination of the sensitivity of decisions
