Physical testing of rubber - Determination of electric strength Ingestion-build-48183 Installation of transformersWhat is BS 903 C4 Methods of testing vulcanized rubber about? BS 903 C4 gives two methods of determining the short time electric strength (breakdown voltage) of insulating vulcanized rubber (including ebonite) and of solid plastics materials using a voltage with a nominal frequency of 50 Hz. One method described in BS 903 C4 of determining electric strength is by rapidly increasing the voltage until breakdown occurs and the other is by a steady
