Abstract
To provide a method for easily discriminating used and unused gas generators from among gas generators for air bags separated from used cars in a car scrapping process. A method for discriminating between used and unused gas generators according to the present invention is a method for discriminating used and unused gas generators from among gas generators for air bags separated from used cars in a car scrapping process, and this method comprises the steps of: PA1 a) crushing used cars mounted with gas generators each having on a surface thereof a material discoloring according to the surface temperatures in actuating the gas generator to separate the gas generators, and PA1 b) discriminating the gas generators in which surfaces are discolored and the gas generators in which surfaces are not discolored from among the separated gas generators.
