Hot Wire Coil Ignition Tester / HWC / IEC 60695-2-20, KS C IEC 60695-2-20
Hot wire coil ignition tester measures the specimen’s ignition time during hot coil is heated electrically. After heating the specimen that flows electricity by rolling it with hot coil which produces 0.25 ~ 0.27 W/㎜ linear power density to 120 seconds, this equipment records the time it is ignited.
