IEC 60216-4-1:1990 Guide for the determination of thermal endurance properties of electrical insulating materials; part 4: ageing ovens; section 1: single-chamber ovens
This specification covers minimum requirements for ventilated and electrically heated single-chamber ovens@ with or without forced air circulation@ for thermal endurance evaluation of electrical insulation. It covers ovens designed to operate over all or part of the temperature range from 20 ??above ambient to 500 ?? It gives acceptance tests and in-service monitoring tests for ageing ovens. Note.- Requirements for multiple-chamber ovens are under consideration.
