This document specifies the characteristics of valves or valve bodies made from polyethylene (PE) for buried and above ground applications, intended for the conveyance of water for human consumption, raw water prior to treatment, drains and sewers under pressure, vacuum sewer systems, and water for other purposes, with the exception of industrial applications.
NOTE 1   For PE components intended for the conveyance of water for human consumption and raw water prior to treatment, attention is drawn to 6.4. Components manufactured for water for other purposes, drains and sewers, and vacuum systems are possibly not suitable for water supply for human consumption.
NOTE 2   Industrial application is covered by EN ISO 15494 [2].
The intended use includes sea outfalls, laid in water and pipes suspended below bridges.
It is applicable to isolating unidirectional and bi-directional valves with spigot ends or electrofusion sockets intended to be fused with PE pipes or fittings conforming to EN 12201-2 and EN 12201-3 respectively.
Valves made from materials other than PE, conforming to the relevant standards can be used in PE piping systems according to EN 12201, provided that they have PE connections for butt fusion or electrofusion ends, conforming to EN 12201-3, or material transition joints (e.g. flanged joints).
NOTE 3   For valves or valve bodies intended for drains and sewers, additional information is given in Clause 9.
It also specifies the test parameters for the test methods referred to in this document.
In conjunction with EN 12201-1, EN 12201 2, EN 12201 3 and EN 12201 5, this document is applicable to PE pipes, fittings and valves, their joints and joints with components of PE and other materials intended to be used under the following conditions:
a)   allowable operating pressure, PFA, up to 25 bar ;
b)   an operating temperature of 20 °C as a reference temperature.
NOTE 4   For applications operating at constant temperature greater than 20 °C and up to 50 °C, see EN 12201-1:2024, Annex A.
The EN 12201 series covers a range of allowable operating pressures and gives requirements concerning colours and additives.
NOTE 5   It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national guidance or regulations and installation practices or codes.
This document covers valves for pipes with a nominal outside diameter dn ≤ 400 mm.

ISO 1452-4:2009 specifies the characteristics of valves made from unplasticized poly(vinyl chloride) (PVC‑U) for piping systems intended for water supply and for buried and above-ground drainage and sewerage under pressure. It also specifies the test parameters for the test methods referred to.
In conjunction with ISO 1452-1, ISO 1452-2, ISO 1452-3 and ISO 1452-5 it is applicable to PVC‑U valves with components of PVC-U, other plastics and non-plastics materials intended to be used for the following:
- 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.

Industrial valves - Functional safety of safety-related automated valves
SIST EN 17955:2024

This document defines the requirements for how mechanical compliant items in a final element can be evaluated according to the principles of EN 61508 to integrate them into a safety-related system. It provides a method to determine all relevant factors, associated with the product, and thereby meet the specific needs of users of the product.
The basic prerequisite for the application of this document is that the intended use is known. This document describes a system to minimize systematic faults to achieve the targeted Safety Integrity Level (SIL).
This document is applied to single compliant items (e.g. valve, actuator or mechanical portions of solenoid valves) or to assemblies of several of these compliant items and interconnecting compliant items and components (e.g. gears, adaptors, brackets, etc.). Electrical, electronic or programmable electronic components are assessed according to EN 61508.
This document does not apply to:
-   manually operated valves;
-   items in safety systems or risk-reducing devices that are not assessed and operated according to the principles of functional safety (e.g. automatic safety valves like pressure relief valves).
The methods described can also be used for other mechanical compliant items in a final element of the safety-related system if the applicability is confirmed by appropriate expert knowledge (e.g. dampers, brakes, clutches).
