### BULLETIN - JM Eagle

loaded and experience wall crushing when their load limit is reached. This mode of failure for rigid pipes has given rise to the terms “crush strength” and “D-Load”, but these terms do not apply to PVC pipes. When a PVC pipe encounters external loading, its diameter will begin to deflect, meaning its sides will

### Product & Technical FAQs from Advanced Drainage Systems

When specifying pipe, the crush strength is a term used for pipes that experience a brittle failure. 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.
