IEC60950-1 Hot Wire Ignition Tester, Annealing Time 8s-12s, Power 0.26W/mm±4%
M.1
Hot
wire
ignition
test
M.1.1
Five
samples
of
each
material
shall
be
tested.
The
samples
shall
be
1
50
mm
long
by
1
3
mm
wide,
and
of
uniform
thickness
stated
by
the
material
manufacturer.
Edges
shall
be
free
from
burrs,
fins,
etc.
M.1.2
A
(250
±
5)
mm
length
of
nichrome
wire
(80
%
nickel,
20
%
chromium,
iron
free)
approximately
0,5
mm
diameter
and
having
a
cold
resistance
of
approximately
5,28
Ω
/m
shall
be
used.
The
wire
shall
be
connected
in
a
straight
length
to
a
variable
source
of
power
which
is
adjusted
to
cause
a
power
dissipation
of
0,26
W/mm
in
the
wire
for
a
period
of
8
s
to
1
2
s.
After
cooling,
the
wire
shall
be
wrapped
around
a
sample
to
form
five
complete
turns
spaced
6
mm
apart.
M.1.3
The
wrapped
sample
shall
be
supported
in
a
horizontal
position
and
the
ends
of
the
wire
connected
to
the
variable
power
source,
which
is
again
adjusted
to
dissipate
0,26
W/mm
in
the
wire
(see
Figure
M.1
).
M.1.4
Start
the
test
by
energizing
the
circuit
so
that
a
current
is
passed
through
the
heater
wire
yielding
a
linear
power
density
of
0,26
W/mm.
M.1.5
Continue
heating
until
the
test
specimen
ignites.
When
ignition
occurs,
shut
off
power
and
record
time
to
ignite.
Discontinue
the
test
if
ignition
does
not
occur
within
1
20
s.
For
specimens
that
melt
through
the
wire
without
ignition,
discontinue
the
test
when
the
specimen
is
no
longer
in
intimate
contact
with
all
five
turns
of
the
heater
wire.
M.1.6
The
test
shall
be
repeated
on
the
remaining
samples.
M.1.7
The
average
ignition
time
and
the
thickness
of
each
set
of
specimens
shall
be
recorded.
Standard:IEC60950-1 ,IEC60947-1:2011,IEC60695-2-20. Flammability Testing Equipment
Application:It is suitable for electric and electronic products, household appliance materials to do ignition dangerous test. It simulates the heat source or ignition source of simulates glow component and overload resistance which may cause thermal stress in a short time.
Test sample:Information technology equipment, low voltage switch and control equipment parts. Flammability Testing Equipment
Feature:Hot-wire coil ignition test adopts the specific size (ф0.5mm length:250mm) and specific material (Ni80/Cr20) of heater strip which is pre-annealed with required heating power(0.26W/mm) and time (8s～12s). Then coil heater strip on the specimen for 5 cycles according to certain wire wrapping tension (5.4N) and certain wire wrapping distance (6.35mm). Next, take the specimen with wrapping heater strip to test until 120s under the stipulate heating power (0.26W/mm) the users can judge the fire risk according to whether the specimen ignite and the ignite time.
