The pipe is compressed between two platens in order to gather load-deflection data. Load measurements are taken at constant intervals.
The external loading properties of plastic pipe obtained by this test method are used for the following:
To determine the stiffness of the pipe. This is a function of the pipe dimensions and the physical properties of the material of which the pipe is made.
To determine the load-deflection characteristics and pipe stiffness which are used for engineering design (see Appendix X1).
To compare the characteristics of various plastics in pipe form.
To study the interrelations of dimensions and deflection properties of plastic pipe and conduit.
To measure the deflection and load-resistance at any of several significant events if they occur during the test.
This test method covers the determination of load-deflection characteristics of plastic pipe under parallel-plate loading.
This test method covers thermoplastic resin pipe, reinforced thermosetting resin pipe (RTRP), and reinforced polymer mortar pipe (RPMP).
The characteristics determined by this test method are pipe stiffness, stiffness factor, and load at specific deflections.
