ASTM C 518 Protective Plate Heat Flux Meter Method Thermal Conductivity Tester
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.
