    Withdrawn Rationale:

    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.

    Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, this practice was withdrawn in January 2014 in accordance with section 10.6.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

    1. Scope

    1.1 This specification covers forced-convection ventilated electrically-heated ovens, operating over all or part of the temperature range from 20C above the ambient temperature to 500C, 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 D 2436. This specification and an associated test method, D5374, have replaced Specification D 2436.

    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.
