Abstract

PURPOSE: To reduce the test time greatly by giving the accelerated heat deterioration to the plastic material in the heating atmosphere of the halogn-group gas and then giving the test to the plastic in the temperature time of several steps.
CONSTITUTION: The mixture is given by mixer 5 between the carrier gas supplied from compressor 2 and the halogen-group gas from cylinder 1 filled with the chlorine, hydrogen chloride, hydrogen bromide or the like. This mixture gas is led to chamber 9 from tube 8. Chamber 9 receives the temperature control by heating device 10 such as the constant temperature bath, the heater or the like, and sample 12 is hung down inside chamber 9 by holder 11. The gas in chamber 9 plus the gas caused by deterioration of the test sample are exhausted through exhaustion mouth 15 and via exhasution tube 13. In such way, the test is carried out in several steps of temperature and time, thus reducing the test time down to one to several or several tens minute.
