Electronic Test Equipment IEC60695-5-10 Glow Wire Testing Equipment
Application
• The Glow Wire Tester is designed to carry out fire hazard testing on electro technical
products in accordance with the provisions of International
standards.
• The control unit is supplied with all the controls and metering
necessary to accurately set the temperature of the glow wire. The
wire current is continuously variable by means of the panel-mounted
controller and is monitored by the built-in ammeter.
• A digital temperature indicator is fitted which, in conjunction
with the thermocouple supplied, accurately measures the glow wire
temperature. The electrical circuit of the control unit is fully
protected by fuses and a miniature circuit breaker and incorporates
mains on/off switching and push button control of the output
current. Self contained cabinet with large viewing window and dark
colored interior.

| Glow-wire |
Glow-wire material: Nickel/Chromium (>77 %Ni/20 ± 1 %Cr)
Diameter: 4,0 mm ± 0,07 mm (before bending)
| | | A new glow-wire shall be annealed for a total of at least 10 h by
being subjected to a current of at least 120 A before being used
for a test run. The total annealing time may be achieved
cumulatively. To avoid damage, the thermocouple shall not be
installed during annealing. At the end of annealing, the depth of
the thermocouple pocket hole shall be verified. | | Timer | 0-30s ±1s | | Force to the test specimen | 0,95 N ± 0,10 N | | glow-wire into and through the test specimen | 7 mm ± 0,5 mm. | | Speed | 10 mm/s to 25 mm/s | | fine-wire thermocouple | nominal diameter of 1,0 mm. The thermocouple wires shall be
suitable for continuous operation at temperatures up to 960 °C
(e.g. chromel/alumel (Type K) – see IEC 60584-1). The welded point
shall be located inside the sheath as close to the tip as
practicable. The sheath shall consist of a metal resistant to
continuous operation at a temperature of at least 1 050 °C. | | Temperature range | 500-1000C° | | Chamber | having a volume of at least 0,5 m3 , dark background, illumination £ 20 lx. | | Initial calibration report: | Required. And shall include the Temperature vs current chart in the
report also

Standards
IEC60695 - 2 - 10 / 11 / 12 / 13,IEC60884-1,IEC60335-1,VDE0620 What is glow wire capable? Glow wire compatibility is a test that ensures safety and avoids mishaps caused by human mishandling, over-current, or
short circuit failures especially within appliance wiring systems.
... Glow wire test is made mandatory under the IEC 60335-1 safety
standards. |
