In order to find out the general view of mechanical properties fro rigid PVC plates as a whole, the measured values of various kinds of mechanical properties have been investigated with respect to their mutual relations about ten kinds of plates. The results obtained are summarized as follows: (1) There exists a close relationship between the results of tensile tests and those of impact tests. The plate which shows more sudden necking phenomenon at its arising in the tensile test, has lower impact strength. (2) There are roughly linear relationships between any tow of the Vickers, the Brinell, the Rockwell and the Shore-rebound hardnesses. The values of H_V/σ_1 (H_V: Vickers hardness, σ_1: tensile strength, i.e. yield strength) take roughly a constant value, i.e. 2.3. (3) The rigid PVC plate which shows higher modulus of elasticity, has higher yield strength (tensile strength), higher hardness, smaller elongation and lower impact strength. There are roughly linear relationships between any tow of the measured values of above mentioned mechanical properties
