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 Method Sections Electrical Tests of Insulation-In-Process 4 - 8 DC proof test 8 Insulation defect or fault rate 7 Spark test 6 Electrical Tests of Completed Wire and Cable 9 - 51 Attenuation 24 Attenuation, effects due to aging 31 Attenuation, effects due to elevated temperature 29 Attenuation, effects due to humidity 30 Attenuation to crosstalk ratio-far end (ACR-F) 28 Attenuation to crosstalk ratio-near end (ACR-N) 26 Capacitance deviation 19 Capacitance difference 20 Capacitance unbalance, Pair-to-ground (CUPG) 22 Capacitance unbalance, Pair-to-pair (CUPP) 21 Capacitance unbalance, Pair-to-support wire 23 Characteristic Impedance-Method 1 Propagation constant and capacitance 47 Characteristic Impedance-Method 2, Single-ended measurements 48 Characteristic Impedance-Method 3 Least Squares Function Fit 49 Coaxial capacitance (capacitance to water) 17 Conductor continuity 11 Conductor resistance (CR) 13 Conductor resistance unbalance (CRU of pairs) 15 Continuity of other metallic elements 12 Crosses test (continuity between wires of different pairs) 35 Crosstalk loss, far-end 27 Crosstalk loss, near-end 25 DC proof test, Core-to-internal shield (screen) 40 DC proof test, Core-to-shield 38 DC proof test, Core-to-support wire 39 DC proof test, Internal shield (screen)-to-shield 41 DC proof test, Other required isolations 42 DC proof test, Wire-to-wire 37 Fault rate test (air core only) 33 Insulation resistance (IR) 32 Jacket voltage breakdown rating test 36 Mutual capacitance (CM) 18 Mutual conductance 16 Phase Constant 44 Phase Delay 45 Phase Velocity 46 Resistance of other metallic cable elements 14 Shorts test (continuity between wires of a pair) 34 Structural Return Loss and Return Loss 50 Unbalance attenuation (conversion losses) 51 Voltage surge test 43 1.3 The values stated in inch-pound units are to be regarded as standard....
