GB/T 3048.4-2007 Test methods for electrical properties of electric cables and wires—Part 4:Test of DC resistance of conductors

Scope

This part of GB/T 3048 specifies the test equipment, sample preparation, test procedures, test results, and calculations and test records for the DC resistance test of conductors. The test methods specified in this part are applicable to measuring the DC resistance of wire and cable conductors, with a measurement range of: — Two-arm bridge: (2×10-5 to 99.9)Ω; — Single-arm bridge: 1 Ω to 100 Ω and above. The test methods specified in this part are not applicable to measuring the DC resistance of installed wire and cables. This part should be used in conjunction with GB/T 3048.1.
