METHODS
MANUAL
1
Scope
The
purpose
of
this
test
method
is
to
measure
the
amount
of
chlorine
and
bromine
compounds
in
base
materi¬
als.
This
test
method
is
applicable
to
reinforced
base
materi¬
als
with
a
minimum
thickness
of
0.3
mm
[0.012
in]
and
to
un-reinforced
base
materials
with
a
minimum
thickness
of
0.08
mm
[0.0031
in].
A
combustion
flask
is
used
to
extract
ionic
and
covalent
halo¬
gen
from
the
sample,
and
Ion
Exchange
Chromatography
is
used
for
the
quantitative
analysis
of
halogen
content.

Procedure
5.1
Combustion
Procedure
Weigh
the
specimen
using
the
analytical
balance
and
record
the
result.
Place
approximately
50
ml
alkali
solution
in
a
combustion
flask
to
act
as
an
absorbent
of
combustion
gas.
Fill
the
combustion
flask
with
oxygen.
Insert
a
test
specimen
into
the
combustion
flask
as
shown
in
Figure
1.
Insert
a
piece
of
filter
paper
into
the
combustion
flask
as
shown
in
Figure
1
to
act
as
a
fuse/flame
starter.
Apply
several
drops
of
ethyl
alcohol
on
the
test
specimen
for
improving
the
ignition
of
the
specimen
and
then
ignite
the
specimen.

Leave
the
flask
at
room
temperature
for
30
min
±
2
min
after
combustion.
The
generated
gas
is
absorbed
into
the
alkali
solution
to
produce
CI7Br_
ion
solution.
Transfer
the
solution
from
the
combustion
flask
to
a
volumet¬
ric
flask.
Introduce
deionized
water
in
the
flask
until
the
total
amount
is
100
ml
of
the
test
solution.
Remove
the
suspended
subjects
from
the
test
solution
by
fil¬
tration
or
centrifugation
if
necessary.
Follow
the
same
procedure
outlined
above
without
the
test
specimen
to
prepare
a
reference
test
solution
(blank)
without
combustion
of
a
test
sample.
Chlorine
and
bromine
contents
shall
be
measured
beforehand
without
any
test
specimen
in
the
combustion
flask.
5.2
Chemical
Analysis
Inject
the
test
fluid
gathered
from
the
flask
in
5.1
into
the
inlet
of
an
ion
exchange
chromato¬
graph
shown
in
Figure
2.
Analyze
the
peak
area/height
of
the
CI7Br_
conductivity
on
the
recorder
and
obtain
C
「/B「
concentration
from
a
calibration
curve.
Obtain
CI7Br
ion
concentrations
of
the
reference
by
compar¬
ing
its
conductivity
using
the
standard
solution.
The
test
solution
is
compared
to
the
reference
solution
(blank).
Any
IPC-2341-2
contaminant
in
the
reference
solution
will
be
subtracted
from
the
test
solution.
Titrate
test
solution
using
silver
nitrate
if
concentration
of
CI7
Br_
ions
is
higher
than
1
wt%.

Halogen
Content
Insert

concentra¬
tion
of
halogen
ion
(CI7BQ
obtained
in

in
the
following
for¬
mula
to
obtain
halogen
contents
in
the
specimens:
Chlorine

For
the
bromine
content,
use
the
same
equation
but
insert
Br
values
in
the
place
of
The
dilution
ratio
is
the
amount
of
added
water
as
com¬
pared
to
the
total
amount
of
solution
in
the
test
flask.
If
the
amounts
used
were
50
ml
each,
the
dilution
ratio
would
be
2.
