Standard:
IEC60695-11-3 ‘Fire hazard testing – Part 11-3: Test flames – 500 W
flames – Apparatus and confirmational test Methods’;
IEC60695-11-4 ‘Fire hazard testing – Part 11-4: Test flames – 50 W
flames – Apparatus and confirmational test Methods’;
IEC60695-11-10 ‘Fire hazard testing – Part 11-10: Test flames – 50
W horizontal and vertical flame test methods’;
IEC60695-11-20 ‘Fire hazard testing – Part 11-20: Test flames –
500W flame test method’.
Application:
This horizontal and vertical flame test apparatus is intended to
compare the burning behaviour of different materials used in
electrotechnical products when vertically or horizontally oriented
test bar specimens are exposed to a small flame ignition source
with a nominal thermal power of 50 W and 500 W.
Test items:
50W Horizontal burning test;
50W Vertical burning test;
500W Horizontal burning test;
500W Vertical burning test. Flammability Testing Equipment
Horizontal burning test is intended to determine the linear burning
rate of materials under specific test conditions. Vertical burning
test is intended to determine whether materials self-extinguish
under specific test conditions.
Fire tests made on a material under the conditions specified can be
of considerable value when comparing the relative burning behaviour
of different materials, controlling manufacturing processes or
assessing any change in burning characteristics. The results
obtained from these fire test methods are dependent on the shape
and orientation of the test specimen, on the environment
surrounding the test specimen, and on the conditions of ignition.
The significant feature of these fire test methods is the
arrangement of the test specimens in either a horizontal or a
vertical position. These testing arrangements make it possible to
distinguish between different classes of material flammability.
