1 Scope This part of GB/T 3048 specifies the test apparatus, specimen preparation, test procedures, test results and calculation, and test records of test of volume resistivity of semi-conducting rubbers and plastics. The test methods specified in this part are applicable to the measurement of volume resistivity of semi-conducting rubbers and plastics for electric cables and wires. The measuring range does not exceed 106Ωcm. This part shall be used in combination with GB/T 3048.1. 2 Normative references The following documents contain provisions which, through reference in this part of GB/T 3048, constitute provisions of this part. For dated references, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent Editions of the normative documents indicated below. For undated references, the latest editions apply to this part. GB/T 3048.1 Test methods for electrical properties of electric cables and wires - Part 1: General 3 Test apparatus The schematic wiring diagram of measuring system is as shown in Figure 1.
