TEST
METHODS
MANUAL
1
Scope
This
method
defines
the
procedure
for
determin¬
ing
the
roughness
or
profile
of
metallic
foils.
1.1
The
surface
finish
or
roughness
of
foils
shall
be
evalu¬
ated
using
Ra.
Ra
is
defined
as
the
arithmetic
average
value
of
all
absolute
distances
of
the
roughness
profile
from
the
center
line
within
the
measuring
length.
1.2
The
foil
profile
of
foils
shall
be
evaluated
using
the
parameter
Rz
(DIN)
or
RTM,
which
is
defined
as
the
average
maximum
peak
to
valley
height
of
five
consecutive
sampling
lengths
within
the
measurement
length.
This
value
is
approxi¬
mately
equivalent
to
the
values
of
profile
determined
from
microsectioning
techniques.
1.3
Rz
(ISO)
is
a
different
parameter
from
Rz
(DIN)
and
is
not
applicable
to
this
method.

Procedure
5・1
Check
the
profilometer
calibration
using
the
appropriate
roughness
standard
for
the
value
Ra
or
RZD,N
(RTM)
and
mag¬
nitude
to
be
measured.
Insure
the
stylus
moves
perpendicular
to
the
grooves
and
the
surface.
Note:
For
Rz
measurements,
known
standards
are
available
in
1
,
3
and
1
0
micrometer
nominal
values.
See
footnote
2.2
5.1.1
Compare
the
values
obtained
on
six
different
mea¬
surements
taken
at
different
locations
within
the
standard
to
the
certified
(not
nominal
value)
of
the
standard.
If
the
average
result
is
not
within
2%
of
the
standard
value,
adjust
the
instru¬
ment
and
repeat
5.1
until
this
tolerance
is
achieved.
5.2
Place
the
foil
test
specimen
on
the
plate
glass
surface
with
the
side
to
be
tested
away
from
the
glass.
Secure
the
specimen
with
tape
or
a
weight
at
both
ends
to
prevent
move¬
ment
or
buckling
during
the
measurement.
