    Withdrawn Rationale:

    These test methods cover procedures for testing fully cured silicone rubber-coated glass fabric and tapes to be used for electrical insulation.

    Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, these test methods were withdrawn in August 2019. This standard is being withdrawn without replacement because the only document known to reference it, MIL-I-46852C, MILITARY SPECIFICATION: INSULATION TAPE, ELECTRICAL, SELF ADHERING UNSUPPORTED SILICONE RUBBER, was cancelled in 1998.

    1. Scope

    1.1 These test methods cover procedures for testing fully cured silicone rubber-coated glass fabric and tapes to be used for electrical insulation.

    1.2 The procedures appear in the following order:
