Rubber, vulcanized or thermoplastic. Accelerated ageing and heat resistance tests Ingestion-build-67170 or for the field strength1 Scope This International Standard specifies accelerated ageing or heat resistance tests on vulcanized or thermoplastic rubbers. Two methods are given: Method A: air oven method using a cell type oven or cabinet oven with low air speed and a ventilation of 3 to 10 changes per hour; Method B: air oven method using a cabinet oven with forced air circulation by means of a fan and a ventilation of 3 to 10 changes per hour.
