LRPL-300 ASTM C 518 Protective Plate Heat Flux Meter Method Thermal
Conductivity Tester
1.Scope of Application:
The thermal conductivity tester mainly tests plastic, rubber,
glass, fiberboard, benzene board, extruded board, foamed concrete,
hollow glass, wood, all kinds of insulation materials and other
uniform plate materials, and can measure the thermal conductivity
of particles, bulk materials, soft materials and other substances.
The protective measuring and control device can effectively
eliminate the influence of the environment on the test and ensure
the test accuracy and repeatability.
2.Standard:
In accordance with GB/T10295-2008 "Heat flux meter method for
determination of steady-state thermal resistance and related
properties of adiabatic materials" and ISO/DIS8301 "Adiabatic -
Determination of steady-state thermal resistance and related
properties ---- heat flux meter device", ASTM C518-04 test method
for determination of steady-state heat flux and heat transfer
characteristics by heat flux meter method.
