Brief Introduction
Needle Flame Tester is a simulation experiment project using non-flame ignition source in accordance to standard requirements of IEC60695 -11-5,GB/T5169.5-2008,GB4706.1-2005 ,etc.
Needle Flame Tester uses Needle-shaped burner in required size (Φ0.9mm ) ;transport butane gas into it ,ignite the specimen at a regular time and angle of 45° ,to check whether the specimen ignite ,lasting ignition time and combustion length to test the ignition fatalness of devices inside because of flammule caused by breakdown.
Needle Flame Tester is suitable for research,production and quality testing department of electrical devices and component parts like lighting equipment,low voltage apparatus,household appliance,machine tool electric appliance,motor-driven machine,electric tool,electronic instrument,electrical connectors and accessories;also suitable for insulating material,engineering plastic and other solid combustible material industry.
