TEST
METHODS
MANUAL
1
Scope
This
test
method
specifies
two
methods
for
the
determination
of
the
acid
value
of
a
flux
of
type
L,
M
or
H.
Method
A
is
a
potentiometric
titration
method
and
is
to
be
considered
the
reference
method.
Method
B
is
an
alternative,
visual
end-point,
titration
method.

2-propanol
(4.2.2).
Alternatively,
pre¬
pare
a
0.1
M
tetrabutyl
ammonium
hydroxide
solution
by
dilut¬
ing
a
commercial
concentrated
solution
with
2-propanol
and
standardize
this
solution
against
an
accurately
weighed
amount
of
benzoic
acid
(about
0.5
g)
dissolved
in
dimethylfor¬
mamide,
previously
neutralized
to
thymol
blue.
4.2.2
2-Propanol.
Neutralized
with
tetrabutyl
ammonium
hydroxide
solution
(4.2.1)
to
a
faint
pink
color
using
phenol¬
phthalein
as
an
indicator.
