GB/T 3048.1 wire and cable electrical performance test methods - Part 1. General
3 Terms and Definitions
GB/T 2900.5-2002 established and the following terms and definitions apply to GB/T 3048 this part.
3.1
As determined by the surface of the conductive portion of the insulation resistance.
Note 1. The surface resistance is generally greatly influenced by the environment.
Note 2. The power of time often uncertain manner exert dramatic effects on surface currents. When measuring, electronic time often take 1min.
3.2
Converted into a surface resistance per unit area when.
Note 1. The surface resistivity is affected by electrode polarization may exist.
Note 2. The value of surface resistivity regardless of the size of the unit area.
3.3
In contact with the insulating dielectric between two electrodes, the voltage applied to the process.
4 Test Equipment
4.1 Test Chamber
4.1.1 chamber shown in FIG
1, will be transparent glass or organic glass. Box size should be able to ensure that the sample is not any and cabinet
What side collide. Lid and the box should be well sealed, so that the minimum amount of air exchange.
4.1.2
The lead wire should be high insulation resistance wire (such as polytetrafluoroethylene insulated wire). When no sample at a predetermined temperature and relative humidity […]
