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 These test methods appear in the following sections of this standard: Test Method Sections Electrical Tests of Insulation—In-process 5 – 9 DC proof test 9 Insulation Defect or Fault Rate 8 Spark Test 7 Electrical Tests of Completed Wire and Cable 10 – 52 Attenuation 25 Attenuation, Effects Due to Aging 32 Attenuation, Effects Due to Elevated Temperature 30 Attenuation, Effects Due to Humidity 31 Attenuation to Crosstalk Ratio—Far End (ACR-F) 29 Attenuation to Crosstalk Ratio—Near End (ACR-N) 27 Capacitance Deviation 20 Capacitance Difference 21 Capacitance Unbalance, Pair-to-ground (CUPG) 23 Capacitance Unbalance, Pair-to-pair (CUPP) 22 Capacitance Unbalance, Pair-to-support Wire 24 Characteristic Impedance—Test Method 1: Propagation Constant and Capacitance 48 Characteristic Impedance—Test Method 2: Single-ended Measurements 49 Characteristic Impedance—Test Method 3: Least Squares Function Fit 50 Coaxial Capacitance (Capacitance to Water) 18 Conductor Continuity 12 Conductor Resistance (CR) 14 Conductor Resistance Unbalance (CRU of Pairs) 16 Continuity of Other Metallic Elements 13 Crosses Test (Continuity Between Wires of Different Pairs) 36 Crosstalk Loss, Far-end 28 Crosstalk Loss, Near-end 26 DC Proof Test, Core-to-internal Shield (Screen) 41 DC Proof Test, Core-to-shield 39 DC Proof Test, Core-to-support Wire 40 DC Proof Test, Internal Shield (Screen)-to-shield 42 DC Proof Test, Other Required Isolations 43 DC Proof Test, Wire-to-wire 38 Fault Rate Test (Air Core Only) 34 Insulation Resistance (IR) 33 Jacket Voltage Breakdown Rating Test 37 Mutual Capacitance (CM) 19 Mutual Conductance 17 Phase Constant 45 Phase Delay 46 Phase Velocity 47 Resistance of Other Metallic Cable Elements 15 Shorts Test (Continuity Between Wires of a Pair) 35 Structural Return Loss and Return Loss 51 Unbalance Attenuation (Conversion Losses) 52 Voltage Surge Test 44 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Sections 7 and 38. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
