From the viewpoint of installation, it is recommended that SN 8 or SN 4 classes are used if the system is to be installed in accordance with national codes of practice for installation in order to achieve the intended r

If the other, less stiff (SN 2), class of pipe or fitting is intended for use then it is recommended that the installation is first subjected to a structural design soil load calculation and the installation technique is modified to suit the results of that calcul

The E modulus for the material can be taken as 1 000 MPa and 500 MPa, for guidance, for the

Attention is also drawn to the Materials selection manual for sewers, pumping mains and manholes (reference WSA/FWR-04).1 Interchangeability For the purpose
12、 of interchangeability with non-pressure underground drainage systems of other materials, it should be noted that PE fittings conforming to BS EN 12666-1:2005 will fit PVC-U pipe conforming to BS EN 1401-1:1998, but PVC-U fittings conforming to BS EN 1401-1:1998 will not necessarily fit PE pipe conf
