Plastics. Polypropylene and propylene-copolymers. Determination of thermal oxidative stability in air. Oven method Ingestion-build-44680 Guidance for the measurement of1 Scope This 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. The stability determined by this method is not directly related to the suitability of the material for use when
