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.

Oct 28, 2013 Strength measurement protocol. Measuring the compressive strength of concrete is achieved by taking a sample of concrete at the time of placement. Cylinders, measuring 12 in. high by 6 in. in diameter, or 8 in. by 4 in., are compressed by a break machine that exerts increasing force upon the cylinder until it structurally fractures.
