IEC60695-2-10 Fire Testing Equipment Glow Wire Tester with
1. Standard of Glow Wire Tester:
The glow wire tester is designed as perIEC60695-2-1,
< basic testing methods of Glow wire, basic methods of Glow wire
device> and IEC829, UL 746A, DIN695, VDE0471 etc. standards.
2. Introduction of Glow Wire Tester
The glow wire tester is designed to carry out fire hazard testing
on electrotechnical products in accordance with the provisions of
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

What is Glow Wire Testing?
Glow wire testing is an electrical safety test designed to evaluate
the flame resistant properties of plastic materials used in
electrical devices. IEC60695-2-11 describes the glow-wire test
conducted on end products (the GWEPT, or glow-wire end product
test). Its purpose is to ensure the end product does not ignite or
spread flames should an ignition source (such as an overheated
part) come into contact with the plastic material. This may occur
in normal use, under reasonable abnormal use, malfunction or
failure of the product. The glow wire simulates an over-heated part
which then comes into contact with plastic materials.
In this part of the standard, the specimen to be tested is the end
product, preferably the entire product if this is possible. The
glow wire is either applied to the area most likely to come into
contact with an ignition source, or the area of the product where
the plastic material is the thinnest. The glow-wire is heated to
the required temperature, which is given in the individual product
standards, and then applied to the specimen for 30 seconds. It is
then removed, and the specimen is observed for a further 30
The glow wire test is covered by the International Electrotechnical
Commission (IEC) standard IEC 60695-2 Fire Hazard Testing, with
four parts covering four different aspects of the glow-wire test.
