In other words, the crush strength is the load at which the pipe physically breaks. This is not applicable to a viscoelastic material such as HDPE or an elastic material such as CMP since the material will deflect under load to the point of failure. A HDPE pipe profile can actually deflect until the material is flattened due to reverse curvature.

BULLETIN

A PVC pipe’s resistance to deflection in an unburied state is measured by its “pipe stiffness”. Pipe stiffness is usually less significant than soil stiffness in PVC pipe installations, but in general, a higher pipe stiffness results in a higher load capacity. Soil stiffness is most affected by the level of compac-

Impact Resistance

Very often material selection is determined by multiple requirements. A compromise in material impact resistance does not necessarily mean loss of ductility for your product, however, while even the toughest material fails if the product is not properly designed. Tips how to increase impact resistance with mechanics/geometry can be found here.
