Single Wire Vertical Flammability Test Apparatus

Single Wire Vertical Flammability Test Apparatus (DZ-3) 

1.Introduction

DZ-3 single wire vertical flammability test apparatus is designed according to IEC60332-1, GB/T18380.11, GB/T5169.14. It is adopts Bunsen burner and certain combustion gas, the fire hazard is evaluated by burning rate, after glow time, after flame time and damage length of the specimen. The test apparatus is applied to do the single wire flammability test for lighting appliance, LV appliance, household appliance, motor and etc.
