Scope
Scope: This document specifies the general requirements, metrological characteristics, calibration conditions, calibration items, and calibration methods for multi-parameter water quality analyzers, as well as the expression of calibration results and calibration intervals. This document applies to the calibration of multi-parameter water quality analyzers with the following measurement ranges: - Chemical oxygen demand (COD): (15–1000) mg/L - Total phosphorus: (0–1000) mg/L - Total nitrogen: (0–1000) mg/L - Ammonia nitrogen: (0–100) mg/L Main technical content: 1.
