& en *********1,*2 Introduction: Scr elektroniks have developed
glow wire apparatus to carry out tests specified in safety
standards to check the "resistance to fire" in the moulded
insulator material parts of electrical accessories like switches,
wires, mcb, elcb, etc. Testing of the accessories with regard to
fire hazard is to create exactly the conditions occurring in
practice. For practical purposes, flammability of electro-plastic
parts/products is tested by simulating, as closely as possible, the
actual effects occurring in practice. This test setup does create
such simulation as described in the respective IEC *********0 first
edition ******0, "glowing/hot wire based test methods - glow-wire
apparatus and common test procedure" : *1. Heating element - glow -
wire: Nickel/chromium ( ni/cr - *0:*0 ) wire of 4 mm dia. With a
shape as per standard. *2. Temperature sensor - thermocouple - fine
wire of cr/AL of 0.5 mm dia. Located in 0.6 mm dia. Pocket hole in
glow - wire, to measure glow - wire temperature. Sheath resistant
to ***0 deg. C. *3. Temperature control - micro controller based
pid temperature controller - 4 digit,1 deg. C resolution, with
ambient temperature compensation, (**0 deg. C per min. Ramp). *4.
Temperature range - adjustable up to **0 deg. C. *5. Time
controller - micro controller based timer,4 digit to measure: *6.
Motorised movement of carriage *7. Available models: Semi automatic
operation (gw *1) & automatic operation (gw a 1) *8. Used by
accredited test labs of bureau of Indian standards and 'stqc' who
are members of international electrotechnical commission system for
conformity testing and certification of electrical equipment
(iecee). Note: 1> product is shipped after calibration. 2>
