It is the object of the present work to develop a new device for evaluating the durability of polymeric materials of wide variety the materials of rigid quality under bending and those of flexible quality under compressive deformation.
The advantageous features of this device are summarized as follows:
(1) It permits parallel tests of five specimens simultaneously.
(2) It is equipped with ultraviolet lamps for irradiation, and with apparatus for controlling temperature constant.
(3) It allows continuous recording of dynamic load of the specimens at constant amplitude of deflection and of rise of temperature in them.
(4) Frequency is variable within a range from 300 to 1500 c.p.m.
By preliminary experiments with several samples, the tester has been found to be efficient for the present purpose.
