For calculating the collapse pressure of a pipe, you first need to calculate the Hoop stress, which is given by :- Stress = Circumferencial Force/(radial thickness*axial length) If the stress crosses this value the pipe would collapse.
Class is the classification criteria employ by the manaufacturer to differentiate pipe based on diameter, rating and other criteria. Class 4 just like other classes of pvc pipe can be used for whatever you wish to use it for depending on the location of the pipe and pressure the pipe is subjected to minding the hoop stress equation relations (sigma=Pr/t). Then you can determine which schedule of pipe you actually need.
