ASTM D2861-14

Standard Test Methods for Flexible Composites of Copper Foil with Dielectric Film or Treated Fabrics (Withdrawn 2020)

SIGNIFICANCE AND USE
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.
SCOPE
1.1 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.  
1.2 The procedures appear as follows:

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
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under the jurisdiction of Committee D09 on Electrical and Electronic Insulating Materials, these test methods were withdrawn in August 2020. This standard is being withdrawn without replacement because it is no longer being maintained.
