Plastics - Polypropylene and propylene-copolymers - Determination of thermal oxidative stability in air, oven method (ISO 4577:1983); German version EN ISO 4577:1999
The document specifies a method for the determination of the resistance of moulded test specimens of polypropylene and propylene-copolymers to accelerated ageing by heat in the presence of air using a forced draught oven. The method represents an attempt to estimate the service life of parts fabricated from propylene plastics.
