Standard Specification for Forced-Convection Laboratory Ovens for Evaluation of Electrical Insulation
1.1 This specification covers forced-convection ventilated electrically-heated ovens, operating over all or part of the temperature range from 20°C above the ambient temperature to 500°C, and used for thermal endurance evaluation of electrical insulating materials.
1.2 The specification requirements for Type I ovens are based on IEC Publication 216-4-1, and are technically identical to it. The requirements for Type II ovens are essentially identical to the requirements of Specification D2436. This specification and an associated test method, D5374, will eventually replace Specification D2436.
1.3 While the ovens covered by this specification are intended primarily for thermal endurance evaluation, they can also be used wherever their characteristics make them suitable for other applications.
1.4 This specification does not address safety aspects. If it is anticipated that oven contents or the location in which the oven is to be installed may create a hazard, the purchaser should determine and specify what additional requirements are needed.
