Gives the minimum requirements for ventilated and heated multi-chamber ovens used for thermal endurance evaluation of electrical insulation and of any other appropriate thermal conditioning application where it is inappropriate to use single-chamber ovens. Covers ovens that are designated to operate over all or part of the temperature range from 20 K above ambient to 500 Deg C. Gives in-service monitoring and acceptance tests for both loaded and unloaded multi-chamber ovens and use conditions.
