This section GB/T 3048 Part 7.
This Part replaces GB/T 3048.7-1994 "wire and cable electrical performance test method of tracking test." This revision follows
GB/T 1.1-2000 "Standardization Guide Part 1. Standard Structure and Writing Rules" This section has been adjusted.
This section compared with GB/T 3048.7-1994 main changes are as follows.
--- Standard English name changed to "Testmethodsforelectricalpropertiesofelectriccablesandwires-
Part 7. Trackingresistancetest ";
--- The overall structure and layout of this section has been modified according to GB/T 1.1-2000.
1) Chapter 1 is "Scope" (Chapter 1 of the.1994 edition; Chapter 1 of this edition);
2) Chapter 2 is "Normative references" (Chapter 2 of the.1994 edition; Chapter 2 of this edition);
3) Chapter 3 is "Terms and definitions" (1994 edition no; Chapter 3 of this edition);
4) Chapter 4 is "Test Equipment" (Chapter 3 of the.1994 edition; Chapter 4 of this edition);
5) Chapter 5, "Specimen Preparation" (Chapter 4 of the.1994 edition; Chapter 5 of this edition);
6) Chapter 6, "Test Procedures" (Chapter 5 of the.1994 edition; Chapter 6 of this edition);
7) Chapter 7 is "Test Results and Assessment" (Chapter 6 of the.1994 edition; Chapter 7 of this edition);
8) Chapter 8, "Test Records" (1994 edition no; Chapter 8 of this edition);
--- Added Chapter 3 "Terms and definitions" (1994 edition no; Chapter 3 of this edition);
--- In Chapter 4 "Test Equipment" made the following changes.
1) Increase the requirement for rapid protection of the test equipment by removing the protective resistor (1994 version 3.1, Figure 1; version 4.2.1,
Figure 1);
2) Added requirements for voltage measuring devices (none in.1994; 4.2.2 in this edition);
3) Supplementing the requirements for the conductivity deviation of the test liquids (3.3 of.1994; 4.4 of this edition);
--- In Chapter 5, "Sample Preparation" to supplement the commonly used preparation methods (1994 version 4.3; version 5.3);
--- In Chapter 6, "Test Procedure" made the following changes.
1) Added Spray Speed (5.2 in.1994; 6.2 in this edition);
2) Incorporate the spray cycle integration into this chapter (6.2 in.1994; 6.2 in this edition);
--- Added Chapter 8, "Test Record", specifies the test record should be recorded in the specific content (1994 edition no; Chapter 8 of this edition).

Electrical properties of wire and cable test methods
Part 7. Electrical tracking test
1 Scope
GB/T 3048 provisions of this section resistance test terms and definitions, test equipment, sample preparation, test procedures, test results
And assessment and test records.
This test method is suitable for testing the ability of wire and cable to withstand damage caused by surface tracking of electric traces under filthy conditions.
Not in accordance with the provisions of the provisions of the results of contamination conditions, can not be compared with the test results obtained by this test method.
This section should be used together with GB/T 3048.1.
