Crush strength is the load at which the pipe physically breaks. A HDPE pipe profile can actually deflect until the material is flattened due to reverse curvature. The best way to test crush strength for HDPE pipes would be AASHTO’s pipe flattening test, which requires the pipe be deflected 20% with no signs of wall buckling, cracking, splitting, or delamination.
