Glow wire tester is designed to carry out flammability test
as per IEC *********0 & bs en *********0 This test is also
referred in IEC ****5, IEC **4/*4, IEC ***8, IEC ****8, IEC
****8, ul **6a, & 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> please send rfq for list of recent
prestigious clients and technical assistance for chosing the
appropriate model as per requirement.
