Measuring method: ASTM E 1530
Thermal Conductivity
Atmosphere: Air
Accuracy: +/- 5%
Description
This instrument is designed for measurement of the thermal conductivity of a planar sample 50mm in diameter or of which one side is 50 mm long.
It is designed in compliance with the ASTM E1530 standard. A variety of planar samples can be measured up to maximum 300°C. The instrument is automated except the setting of sample and permits accurate measurement by simple operation, requiring no special measuring technique or skill.
Specification
(1)Measuring method
Guarded heat flow meter method
ASTM Standard E1530
(2)Temperature range
30 to 300°C (when chiller is used)
40 to 300°C (when city water is used)
(3)Measurement atmosphere
air
(4)Sample size*
a) 50mm dia. or 50mm square X 0,1 to 15 mm thick
b) 25mm dia. or 25mm square X 0,1 to 8mm thick
The thermal resistance of a sample should be within the measuring range (5) ,therefore appropriate thickness varies depending on the thermal conductivity of the sample.
(5)Thermal resistance
a) 0.0005 to 0.03 m2k/W (0.1 to 20 W/mk)
measurement range*
b) 0.0005 to 0.012m2k/W (0.1 to 15 W/mk)
Thermal resistance = thickness/thermal conductivity
Thermal Analysis
