Sliding components of electrical communication apparatus, such as cams and dial switches are frequently used under discontinuous sliding conditions. Wear properties of plastics have so far been investigated under continuous sliding conditions, and have little been investigated under discontinuous sliding conditions. In this paper, wear properties of polyvinyl chloride (PVC) were determined under discontinuous sliding conditions and the results were compared with those determined under continuous sliding conditions. Furthermore, the effect of lubricant content on wear property of PVC was examined under discontinuous sliding conditions. The results obtained are summarized as follows; (1) Under continuous sliding conditions, the wear volume of PVC increased linearly with sliding distance. However, the wear volume increased steeply when sliding distance exceeds a certain value. (2) The wear volume of PVC determined under discontinuous sliding conditions agreed with the value estimated from the slope of the linear region observed under continuous sliding conditions. (3) The wear volume of PVC decreased with increasing lubricant contents under discontinuous sliding conditions.
