Water quality - Sampling - Part 3: Preservation and handling of water samples (ISO/DIS 5667-3:2026)

This document specifies the general requirements for sampling, preservation, handling, transport and storage of all water samples for physicochemical, chemical, hydrobiological and microbiological analyses and determination of radiochemical analytes and activities. Guidance on the validation of storage times of water samples is provided in ISO/TS 5667-25 [2]. This document is not applicable to water samples intended for ecotoxicological assays, biological assays (which is specified in ISO 5667-16 [4]), passive sampling (which is specified in ISO 5667-23 [5]) and microplastics (which is specified in ISO 5667-27 [6]). This document is particularly appropriate when samples cannot be analysed on site and have to be transported to a laboratory for analysis.

Building valves - Hydraulic safety groups - Tests and requirements

This document specifies dimensions, materials and performance requirements, including methods of test, for hydraulic safety groups, of nominal sizes from DN 15 to DN 25, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Hydraulic safety groups are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95 °C. Hydraulic safety groups limit the pressure in hot water heaters, prevent the backflow of water into the main circuit and prevent the discharged water to get into contact with the water in the water heater. Hydraulic safety groups do not control the temperature. They ensure the hydraulic safety of water heaters if the mechanical resistance of the water heater remains at least equal to the rating pressure. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).
