Important
In the application, the products are not intended for use under continuously varying loads. With a continuously varying load is meant here cyclical load with a frequency of at least 1 cycle per minute between 2 load levels.
Note: The product can be used under continuously varying loads in internal pressure applications. In that case, it must be tested according to ISO 15306. Your pipes can be made according to different processes. For instance:
- rotational casting;
- wrapping continuous filament;
- winding filament crosswise.
