ASTM D4566-08e1

Standard Test Methods for Electrical Performance Properties of Insulations and Jackets for Telecommunications Wire and Cable

SIGNIFICANCE AND USE
Electrical tests, properly interpreted, provide information with regard to the electrical properties of the insulation. The electrical test values give an indication as to how the insulation will perform under conditions similar to those observed in the tests. Electrical tests may provide data for research and development, engineering design, quality control, and acceptance or rejection under specifications.
SCOPE
1.1 These test methods cover procedures for electrical testing of thermoplastic insulations and jackets used on telecommunications wire and cable and for the testing of electrical characteristics of completed products. To determine the procedure to be used on the particular insulation or jacket compound, or on the end product, reference should be made to the specification for the product.
1.2 The test methods appear in the following sections of this standard: Test MethodSections Electrical Tests of InsulationIn-Process4-8  DC proof test8  Insulation defect or fault rate7  Spark test6 Electrical Tests of Completed Wire and Cable9-51  Attenuation24  Attenuation, effects due to aging31  Attenuation, effects due to elevated temperature29  Attenuation, effects due to humidity30  Attenuation to crosstalk ratiofar end (ACR-F)28  Attenuation to crosstalk rationear end (ACR-N)26  Capacitance deviation19  Capacitance difference20  Capacitance unbalance, Pair-to-ground (CUPG)22  Capacitance unbalance, Pair-to-pan="top"> Fault rate test (air core only)33  Insulation resistance (IR)32  Jacket voltage breakdown rating test36  Mutual capacitance (CM)18  Mutual conductance16  Phase Constant44  Phase Delay45  Phase Velocity46  Resistance of other metallic cable elements14  Shorts test (continuity between wires of a pair)34  Structural Return Loss and Return Loss50  Unbalance attenuation (conversion losses)51  Voltage surge test43
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.
