ASTM D4566-98

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

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 that product.
1.2 The test methods appear in the following sections of this standard:  Test Method Sections Electrical Tests of Insulation---In Process: 4-8 D-C proof test 8 Insulation defect or fault rate 7 Spark test 6 Electrical Tests of Completed Wire and Cable: 9-37 Attenuation 26 Capacitance deviation 19 Capacitance difference 20 Capacitance unbalance---pair-to-ground 22 Capacitance unbalance---pair-to-pair 21 Capacitance unbalance---pair-to-support wire 23 Coaxial capacitance (capacitance to water) 17 Conductor continuity 11 Conductor resistance 13 Conductor resistance unbalance (pairs) 15 Continuity of other metallic cable elements 12 Crosses test (continuity between wires of different pair) 30 Crosstalk loss---far end 25 Crosstalk loss---near end 24 D-C proof test---core-to-internal shield (screen) 35 D-C proof test---core-to-shield 33 D-C proof test---core-to-support wire 34 D-C proof test---internal shield (screen)-to-shield 36 D-C proof test---other required isolations 37 D-C proof test---wire-to-wire 32 Fault rate test (air core only) 28 Insulation resistance 27 Jacket voltage breakdown rating test 31 Mutual capacitance 18 Mutual conductance 16 Resistance of other metallic cable elements 14 Shorts test (continuity between wires of a pair) 29 Voltage surge test 38
1.3 The values stated in inch-pound units are to be regarded as the standard. SI units are for information only.
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 . Specific hazard statements are given in Sections 6 and 32.
