BS PD CEN/TR 1295-4:2015 lists the parameters for the reliability of the structural design of buried water and wastewater pressure pipelines, drains and sewers.The reliability of the design of buried pipelines is based on the selection of appropriate design parameters for a chosen design method. This document identifies the parameters appropriate to the chosen design method, which should all be clearly stated.This Technical Report does not aim to specify the requirements for the structural design of water and wastewater pressure pipelines, drains and sewers. These requirements are defined in EN 1295-1.This Technical Report does not apply for offshore laying, pipes supported on piles, no dig pipelines, or laid above ground. Supplementary considerations need to be taken into account for these specific installations.Special situations (e.g. landslide, earthquake, fire) are outside the scope of this document.Design parameters for calculation of longitudinal effects (including bending moments, shear forces and tensile forces resulting for example from non-uniform bedding and thermal movements and, in the case of pressure pipelines, from Poisson's contraction and thrust at change of direction or cross-section) are not covered in this document.Cross References:EN 1295-1EN 805CEN/TR 1295-2CEN/TR 1295-3EN 1610EN 1990All current amendments available at time of purchase are included with the purchase of this document.
