Protection against pollution of water intended for human consumption in potable water installations and general requirements for devices to prevent pollution by backflow
oSIST prEN 1717:2023

This document specifies a methodology for protecting potable water in potable water installations within and outside buildings but within premises from the risk of pollution by backflow of non-potable water and gives recommendations on the design, risk analysis, backflow prevention devices and their installation methods.
This methodology is also intended to be used outside premises for all potable water systems connected to a potable water distribution system up to and including the point of use.
The product standards for the specific backflow prevention devices or arrangements are intended to be used in conjunction with this document. In the absence of a product standard, this document is intended to be used as a reference to draw up a specification for the development of new devices or arrangements.

- water mains and services buried in ground;
- conveyance of water above ground for both outside and inside buildings;
- buried and above-ground drainage and sewerage under pressure.
It is applicable to valves in piping systems intended for the supply of water under pressure up to and including 25 °C (cold water) intended for human consumption and for general purposes as well as for waste water under pressure. It is also applicable to valves for the conveyance of water and waste water up to and including 45 °C.

Gas cylinders - Cylinder valves with integrated pressure regulators - Specification and type testing (ISO 22435:2024)
kSIST FprEN ISO 22435:2024

This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases.
These are requirements for VIPRs that are in addition to those given in the relevant closure standard, for example, in ISO 10297 for cylinder valves, in ISO 17871 for quick-release cylinder valves, in ISO 17879 for self-closing cylinder valves or in ISO 23826 for ball valves. For ISO 17871, these requirements are only applicable to quick-release cylinder valves types B, C, D and E.
NOTE 1        If the pressure regulating system of a VIPR is acting as the primary valve operating mechanism, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating system.
NOTE 2        If the primary valve operating mechanism of a VIPR is located at the low-pressure side of the pressure regulating system, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826.
NOTE 3        The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes.
This document does not apply to VIPRs for
a)       medical applications (see ISO 10524-3);
b)       liquefied petroleum gas (LPG);
c)        cryogenic applications.
NOTE 4        Additional requirements for a VIPR with a residual pressure device (RPD) are specified in ISO 15996.
NOTE 5        Additional requirements for pressure relief valves can exist in international/regional regulations/ standards.
