The document specifies, dimensions, materials and performance requirements (including methods of test) for expansion 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).
Expansion groups shall be fitted to the cold potable water supply only for expansion purposes, e.g. of storage water heaters, having a maximum distribution temperature of 95 °C.
Expansion groups limit pressure in the water heater to which they are fitted, that is produced by thermal expansion of the water, prevent the backflow of water into the supply pipe and prevent the discharged water to get into contact with the water in the water heater.
Expansion groups do not control temperature and alone do not constitute the protection required for storage water heaters.
NOTE   The use of the device specified in this Standard does not override the need to use controls (e.g. thermostats and thermal cut-outs) which act directly on the power sources of water heaters.

This document specifies the pipes made from polyethylene (PE) for buried or above ground applications, intended for the conveyance of: — water for human consumption; — raw water prior to treatment; — drainage and sewerage under pressure; — vacuum sewer systems; — water for other purposes. NOTE 1 The intended uses include sea outfalls, laid in water and pipes suspended below bridges. Pipes complying with this document are not intended for the transport of water intended for human consumption in contaminated soils unless special consideration has been taken. NOTE 2 For example, ISO 21004 provides an alternative solution for use in contaminated soils. See Reference [3] in the Bibliography. This document specifies three types of pipe: — PE pipes (outside diameter dn), including any identification stripes; — PE pipes with co-extruded layers on either or both the outside and/or inside of the pipe (total outside diameter dn) where all layers have the same MRS rating; — PE pipes (outside diameter dn) having a peelable and contiguous thermoplastics additional layer on the outside of the pipe ("coated pipe"). This document also specifies the test parameters for the test methods referred to in this document. In conjunction with the other parts of the ISO 4427 series, this document is applicable to PE pipes, their joints and to joints with components made of PE and other materials, intended to be used under the following conditions: a) a maximum allowable operating pressure (PFA) up to and including 25 bar[1]; b) an operating temperature of 20 °C as the reference temperature.

This document specifies the evaluation method of life cycle analysis of ductile iron pipes used for water applications as specified in ISO 2531 and ISO 16631. Studies on economic and environmental impacts are important for utility decision-makers as they seek to balance budget concerns over immediate and long-term needs across acquisition, operations and maintenance, and planned end of life. For authorities and engineers designing pipeline systems, the life cycle cost analysis serves as a tool to study various scenarios to determine the right solution for site-specific conditions and community values, as well as to provide the necessary data to support those decisions. Informative annexes are included in this document as a compilation of reference and consensual factors (pumping cost, leakage incident rate, etc.).
