As a commonly used insulating and protective component in electrical wiring, the flame retardancy of PVC wire ducts is directly related to electrical safety. The flame retardant grade needs to be evaluated through professional testing methods. The following is a detailed description of the flame retardant testing methods and common flame retardant grades of PVC wire ducts:
I. Flame Retardant Testing Methods for PVC Wire Ducts
The flame retardant testing of PVC wire ducts is mainly based on domestic and international standards. By simulating fire scenarios or high - temperature environments, its combustion characteristics, burning rate, flame spread extent, and self - extinguishing ability are tested. The common testing methods and standards are as follows:
1. Vertical Burning Test
Applicable Standards: International Standard: IEC 60695 - 11 - 10 "Fire hazard testing - Part 11 - 10: Test flames - 50W horizontal and vertical flame test methods"
EU Standard: EN 60695 - 11 - 10 (basically the same as IEC)
Chinese Standard: GB/T 5169.16 "Fire hazard testing for electrical and electronic products - Part 16: 50W horizontal and vertical flame test methods"
