--- Part 3. Semi-conductive rubber material volume resistivity test;
--- Part 4. DC resistance of conductors;
--- Part 5. Insulation resistance test;
--- Part 7. Tracking resistance test;
--- Part 8. AC voltage test;
--- Part 9. spark test of insulated cores;
--- Part 10. extruded jacket spark test;
--- Part 11. dielectric loss tangent test;
--- Part 12. Partial discharge test;
--- Part 13. impulse voltage test;
--- Part 14. DC voltage test;
--- Part 16. Surface resistance test.
This section GB/T 3048 Part 3.
This Part replaces GB/T 3048.3-1994 "Test methods for electrical properties of the wire and cable semi-conductive rubber material volume resistivity test."
This revision in accordance with GB/T 1.1-2000 "Standardization Guide Part 1. Standard structure and write rules" for this part of the
Adjustment.
Section compared with the GB/T 3048.3-1994 The main changes are as follows.
--- Standard English name to "Testmethodsforelectricalpropertiesofelectriccablesandwires-
Part 3. Testofvolumeresistivityofsemi-conductingrubbersandplastics ";
--- 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) In Chapter 3, "Test Equipment" (1994 Edition Chapter 3; Chapter 3 of this edition);
4) Chapter 4 of "Sample Preparation" (1994 edition, Chapter 4; Chapter 4 of this edition);
5) Chapter 5 to "test program" (1994 edition Chapter 5; Chapter 5 of this edition);
6) Chapter 6 is "the test results and calculations" (1994 edition, Chapter 6; Chapter 6 of this edition);
7) Chapter 7 is "test records" (1994 edition no; Chapter 7 of this edition);
--- In Chapter 1, "scope" to remove the requirement contained in the section (the 1994 edition of Chapter 1; Chapter 1 of this edition);
--- The following modifications were made in Chapter 3, "Test Equipment".
1) supplementary provisions of the current distance and the insulation resistance between the electrodes (1994 Version 3.2.1; 3.4.1 edition);
2) The modifications to the "precision" provisions of the current measuring instrument is "indication error" provisions (1994 Version 3.3; Excerpts
3.2);
3) supplemented the "show error" predetermined voltage measuring instruments (1994 Version 3.4; 3.3 edition);
4) to modify the thermostat temperature range requirements (1994 Version 3.6; 3.6 edition);
--- In Chapter 4, "Sample Preparation" supplement on specimens cut requirements (1994 Version 4.1; this edition 4,1);
--- Made in Chapter 5, "test procedure" in the following modifications.
1) supplemented with the use of electric current to change the contents of Law (1994 edition 5.3, 5.4; 5.3 edition);
2) Modify the sample measured twice repeated representations (1994 Version 5.5; 5.4 edition);
3) A "working temperature" of volume resistivity test (no 1994 edition; edition 5.6);
--- In Chapter 6, "the test results and calculations", the formula has been modified to express the way (1994 edition 6.1; 6.1 edition);
--- Increase in Chapter 7, "trial record", sets out the specific content of the test records shall set forth (1994 edition free; first edition chapter 7).
