PLC Touch Screeen Flammability Testing Equipment Needle Flame Test
Apparatus
product information:
This part of IEC 60695 specifies a needle-flame test to simulate
the effect of a small flame which may result from fault conditions,
in order to assess by a simulation technique the fire hazard.
It is applicable to electrotechnical equipment, its sub-assemblies
and components and to solid electrical insulating materials or
other combustible materials.
The structure of this tester is stainless steel plate and
high-grade spraying outside box, using the most advanced PLC
control, to achieve intelligent control, standard equip with TFT
true color LCD, can achieve upgrade of the customer's humanized
operation interface, and truly achieve the comparison result of the
international.
The burner to produce the test flame shall consist of a tube at
least 35 mm long with a bore of 0.5mm±0.1mm and outer diameter not
exceeding 0.9mm. The burner is supplied with butane or propane gas
having a purity of at least 95%. There shall be no air admitted to
the burner tube. To evaluate the possibility of spread of fire, for
example by burning or glowing particles falling from the test
specimen, a layer of the material or components normally
surrounding or situated underneath the test specimen and the
surrounding material or components when the test specimen is
mounted as in normal use.
The test flame is positioned so that the tip of the flame is in
contact with the surface of the test specimen. The test flame is
removed after the specified time.
If the test specimen drips molten or flaming material during the
application of the flame, the burner may be tilted up to 45°from
the vertical to prevent material from dripping into the burner tube
while maintaining an 8mm±1mm spacing between the centre of the top
of the burner and the remaining portion of the test specimen,
ignoring any strings or molten material.
It is applicable to lighting, low-voltage electrical appliances,
household appliances, machine tool electric appliance, electric
motor, electric tools, electronic instruments, electrical
instruments, electrical connector, such as electrical and
electronic equipment and parts, components, including insulation
materials, engineering plastic or other solid combustible
materials.
