标准范围

规定了通过加入炭黑制成导电塑料的特殊制备试样的电阻率实验室测试要求。该试验适用于电阻率小于104 Ohm x m的材料。在试样两端的电极之间通过稳定的直流电流。给出了测试电路的原理图。当电流流动时，两个电位电极之间的电压降（设置在试件上）用静电计测量。电势电极之间试样部分的电阻与接触电阻无关。

Specifies the requirements for the laboratory testing of the resistivity of specially prepared specimens of plastics made conductive by the incorporation of carbon black. The test is suitable for materials having a resistivity of less than 104 Ohm x m. A stable d.c. current is passed between electrodes at the ends of a test piece. A schematic diagram of the test circuit is given. The voltage drop between the two potential electrodes, set on the test piece while the current flows, is measured with an electrometer. The resistance of the portion of the test piece between the potential electrodes is independent of contact resistances.
