Section compared with the GB/T 3048.16-1994 The main changes are as follows.
--- Standard English name to "Testmethodsforelectricalpropertiesofelectriccablesandwires-
Part 16. Surfaceresistancetest ";
--- Overall structure and layout of this section according to GB/T 1.1-2000 modified.
1) Chapter 1 of "Range" (1994 edition Chapter 1; Chapter 1 of this edition);
2) Chapter 2 is "normative references" (1994 edition, Chapter 2; edition Chapter 2);
3) Chapter 3 as "Terms and Definitions" (1994 edition no; Chapter 3 of this edition);
4) Chapter 4, to "test equipment" (1994 edition Chapter 3; Chapter 4 of this edition);
5) Chapter 5 is "Sample Preparation" (1994 edition, Chapter 4; Chapter 5 of this edition);
6) Chapter 6 is "Test Program" (1994 edition Chapter 5; Chapter 6 of this edition);
7) Chapter 7 is "the test results and calculations" (1994 edition, Chapter 6; edition Chapter 7);
8) Chapter 8 of "test records" (1994 edition no; Chapter 8 of this edition);
--- In Chapter 2, "Normative references" supplemented with relevant standards (1994 edition Chapter 2; Chapter 2 of this edition);
--- Increased Chapter 3, "Terms and definitions" (1994 edition no; Chapter 3 of this edition);
--- In Chapter 4, "test equipment", the measurement system made the necessary modifications (1994 Version 3.2; 4.2 edition);
--- In Chapter 6, "test procedure" in the environmental conditions of the process to add new regulations (1994 edition free; edition 6.2);
--- Increase in Chapter 8, "trial record", sets out the specific content of the test records shall set forth (1994 edition no; Chapter 8 of this edition).

Electrical wire and cable performance test method
Part 16. Surface resistance test
1 Scope
This section GB/T 3048 specifies the terms and definitions of surface resistance test, test equipment, specimen preparation, test procedures, test results
Fruit and computing and test records.
This section applies to the measurement of the surface resistance of the wire and cable, the measurement range (105 ~ 1015) Ω.

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
