What is ISO 8779 about?

ISO 8779 specifies the characteristics of pipes (mains, sub-mains and laterals) made from polyethylene (PE), intended for the conveyance of water for irrigation, at a water temperature up to 45 °C. ISO 8779 applies to pipes that will not be subjected to internal pressure for long periods, and not more than 1 500 hours/year. For piping applications with long-term continuous pressure, the ISO 4427 series applies. ISO 8779 also specifies the properties of the material and the parameters for the test methods to which it refers. ...
