DIN EN 17075:2017-02

This standard is Part 2 of a two part series of standards defining the technical requirements for testing the performance of water monitoring equipment. This standard defines general requirements and performance test procedures for automated measuring devices (AMD). These devices may be permanently installed or portable and are capable of making continuous real-time re measurements in water of chemicals or physical parameters. Automated measuring devices are used extensively in the industrial process, water industries and by regulators for compliance and surveillance monitoring and process control purposes. The standard supports the Industrial Emissions Directive, Marine Directive and the Water Framework Directive. The test parameters are performance characteristics that identify the capability of an AMD to provide reliable measurements. They include: bias, repeatability and errors caused by variations in linearity, drift, interferents, salinity compensation, output impedance, supply voltage, ambient temperature, relative humidity, incident light, sample temperature, sample flow-rate, sample pressure. The overall measurement reliability of an AMD is calculated in the form of a combined performance characteristic expressed as measurement uncertainty.
