EN 12201-4 is a European standard that specifies requirements and test methods for polyethylene (PE) valves used under pressure in water supply, drainage and sewage. Applies to valves made of PE with a maximum working pressure of 25 bar.
The standard covers a range of issues related to the design, manufacture and testing of PE valves. These include:
Materials: The standard specifies the requirements for materials used to manufacture PE valves. This includes the base resin, additives and pigments.
Dimensions and tolerances: The standard specifies dimensions and tolerances for PE valves. This includes nominal size, end connection types and wall thickness.
Performance requirements: The standard specifies performance requirements for PE valves. This includes testing for resistance to internal pressure, toughness, and resistance to slow crack growth.
Marking: The standard specifies the requirements for marking PE valves. This includes the manufacturer's name, valve material, nominal size, pressure rating and date of manufacture.
Test: The standard specifies test methods for PE valves. This includes testing for resistance to internal pressure, toughness, and resistance to slow crack growth.
The purpose of EN 12201-4 is to ensure that PE valves used in pressurized water supply, drainage and sewerage are safe, reliable and durable. The standard provides a common set of requirements for PE valve manufacturers, installers, and users, and helps ensure that products from different manufacturers are interchangeable and compatible.
EN 12201-4 covers a range of PE valves, including ball valves, diaphragm valves, gate valves, butterfly valves and check valves. The standard also contains information on the installation and use of PE valves, including guidance on storage, handling and maintenance.
