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 13. The partial modification of the use of IEC 60230. 1966 "cables and their accessories impulse voltage test" (in English) and IEC 60060-1. 1989 "High voltage test techniques - Part 1. Definitions and general technical requirements" (in English). This section according to IEC 60230. 1966 and IEC 60060-1. 1989 redrafted. This part of the structure in line with GB/T 1.1- 2000 "Standardization Guide Part 1. Standard structure and drafting rules" and in harmony with the GB/T 3048 in other parts. in Listed in Appendix A of this part of the reg number and IEC 60230. 1966 and IEC 60060-1. 1989 reg control list numbered. Taking into account the development of detection technologies in use IEC 60230. 1966 and IEC 60060-1. 1989 when this part has made several changes, About the technical differences have been incorporated into the body and they are involved in the provision of the margin of a single vertical line identification.
