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.
ISO 8779 will help you improve the quality of polyethylene pipes.
Who is ISO 8779 for?
ISO 8779 on polyethylene (PE) pipes for irrigation — specifications is useful for:
- Polyethylene pipes manufacturers
- Polyethylene pipes designers
Why should you use ISO 8779?
ISO 8779 specifies the minimum requirements from polyethylene irrigation pipes that stay idle most of their life and are only pressurized for short periods from time to time. This condition is true for the majority of irrigation pipes in use, including laterals, sub-mains, and even mains.
ISO 8779 provides you guidance on the material to be used and its geometric, mechanical, and physical characteristics. This will help you improve the quality of polyethylene pipes.
ISO 8779 describes marking instructions that will help you identify and trace the polyethylene pipes.
What’s changed since the last update?
BS ISO 8779:2020 is the fourth edition that cancels and replaces the third edition (ISO 8779:2010), which has been technically revised.
The main changes compared to the previous edition are as follows:
- The scope of this fourth edition has been modified to cover larger sizes of mains and sub-mains of irrigation piping system
