The objective of the present study is to see the applicability of hardness test in order to grasp the mechanical characteristics of plastic pipes. In this paper, the relation between hardness and deflection appearing in a direction parallel or perpendicular to the axis of a plastic pipe has been clarified.
The results obtained are as follows:
(1) Hardness should be measured on the spots at least 20mm apart from the edge of pipe.
(2) Both Vickers and Shore hardness testers can be applied for testing plastic pipes.
