This apparatus is designed to perform tests specified in many standards to check Resistance to Fire in Insulating parts. The testing of electro-technical products for fire hazard is conducted by simulating as closely as possible actual effects occurring in practice. Parts of electro-technical equipment which may be exposed to thermal stress due to electric effects & deterioration of which may impair safety of equipment shall not be unduly affected by heat & fire generated within the equipment.
* Meets requirements of the latest IEC specifications as per IEC 60695-2-10.
* Precision fine wire Cr/Al, insulated junction thermocouple, 0.5 mm dia, to measure Glow-Wire temperature.
* Controling by PLC and operating by touch-screen.
* Motorised specimen carriage preloaded with force of 1.0 N when in contact with Glow-Wire, and carriage is drived by stepper motor.
* Mechanical stopper limits movement of tip of Glow-Wire in to the specimen to 7 mm.
* Universal, adjustable stainless steel perforated tray mounting bracket to fix test specimens.
