Причина отмены These test methods cover procedures for testing flexible materials consisting of copper foil combined with either dielectric film or with treated or impregnated fabric to form flexible composites used in the manufacture of flexible or multilayer circuitry, or both.

Formerly under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, these test methods were withdrawn in August 2020. This standard is being withdrawn without replacement because it is no longer being maintained.

Значение и использование

7.1 The electrical and mechanical characteristics of circuits produced from flexible composites of copper foil with dielectric materials will, to a large extent, depend on the properties of the dielectric portion of the composite. Measurement of these properties is essential for predicting performance of the circuit.
