Q. What does a “Class” number mean in relation to PVC pipe?
A. Class number for PVC pipe denotes its pressure rating; examples are Class 315, Class 200, Class 160, Class 125, etc. This "pressure class" distinction tells you that the pipe is designed to withstand normal pressures of 315 psi, 200 psi, 160 psi, 125 psi, etc. The industry standard is to have a built-in safety factor of 2:1 for pressure surges, so a Class 200 pipe could probably withstand 400 psi water hammer (shock) pressures.
