1.Description:
This
instrument
adopts
the
internationally
popular
method
of
using
thermal
flow
meters
to
measure
thermal
conductivity.
It
is
equipped
with
a
computer
to
achieve
fully
automatic
testing.
It
is
a
re-designed
version
based
on
our
original
DRPL-1
model,
and
is
suitable
for
testing
the
thermal
conductivity
of
various
common
materials.
This
instrument
is
based
on
the
steady-state
plate
method
testing
principle.
A
stable
temperature
is
added
to
the
hot
surface,
and
the
heat
passes
through
the
sample
to
the
cold
surface.
The
transferred
heat
flux
is
measured.
Then,
the
thermal
conductivity
and
thermal
resistance
can
be
calculated
based
on
the
thickness
of
the
sample
and
the
heat
transfer
area.
This
testing
method
is
simple,
fast,
and
has
good
repeatability.
It
is
very
suitable
for
research
and
development
in
material
heat
transfer.
It
can
be
used
for
testing
of
plastics,
rubber,
graphite,
insulation
materials,
etc.,
and
is
widely
applied
in
universities,
research
institutes,
quality
inspection,
factories
and
mines.
2.Standard
ASTM E1530-06 is a testing standard for evaluating the heat conduction resistance of materials using protected thermal flow meter technology; GB/T 29313-2012 is the test method for thermal conductivity performance of electrical insulating materials; ASTM C518-04 is the test method for determining steady-state heat flux and heat transfer characteristics using thermal flow meter; GB 10295-2008 is the test method for determining steady-state thermal resistance and related properties of insulation materials (using thermal flow meter).
