1 Scope This part of GB/T 3048 specifies the test equipment, sample preparation, test procedures, test results, calculation and test records of DC resistance of conductors. The test methods specified in this part are applicable to measure the DC resistance of electric wire and cable conductors. The measurement range is: ——Double bridge: (2 × 10-5 ~ 09.9)Ω; ——Wheatstone bridge: 1Ω ~ 100Ω or above. The test methods specified in this part are not applicable to measure the DC resistance of assembled electric wires and cables. This part shall be used together with GB/T 3048.1. 2 Normative References The provisions of the following documents which, through reference in this part of GB/T 3048, constitute provisions of this part. For dated reference, subsequent amendments to (excluding correction contents), or revisions of, any of these publications do not apply. However, the parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards. For undated references, the latest edition of the normative document referred to applies.
