This European Standard specifies requirements and tests for check valves of thermoplastic materials with the function to allow the flow of liquid fluids through the valve in one direction only and to prevent backflow. This standard is applicable to check valves to be installed in industrial pipe systems, irrespective of the field of application and the liquid fluids to be conveyed. The range of DN is: DN 8, DN 10, DN 15, DN 20, DN 25, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 500 and DN 600. The range of PN and Class is: PN 6, PN 10, PN 16, PN 25, Class 150 and Class 300. The requirements specified by this standard concern the design, functional characteristics and manufacture of check valves, their connection to the pipe system, the body materials and their pressure/temperature rating between - 40 °C up to + 120 °C, for a lifetime of 25 years.
