ASTM C411-82 Thermal Insulation Materials Maximum Use Temperature Test Machine
ASTM C411-82 Introduction:
This machine is based on ISO 8142: 1990 is used to evaluate the
maximum operating temperature of loose-fill insulation materials,
carpets, blankets, blocks, plates, prefabricated pipe insulation
and some insulation products;
ASTM C411-82 Standard:
ASTM C411-82
ASTM C447-85
ISO 8142: 1990
ASTM C411-82 Model: FTech-ISO 8142
ASTM C411-82 Features:
The tester adopts CNC machine processing molding.
circularmodellingis beautiful and generous. It can also be rust
corrosion. other parts use 45 # steel. The surface plating uses
SUS304 stainless steel.
ASTM C411-82 Technical parameters:
1. Heating plate: the heating plate is made of SUS304 stainless
steel.thetest area is about 900 * 450mm, which is surrounded by
80mm wide protective layer. At least five thermocouples
whichisuedto measure the surface temperature is located at the
surface of the heating plate. Four thermocouples are fixed on the
diagonal ofheatingplate heating zone, and the distance of each
corner is about 150mm. The fifth thermocouple is located at
thecentreof the heating plate.
2. Heat pipe: the heating pipe is made of SUS304 stainless
steel.thelength is about 2M, the nominal diameters are about 88mm,
108mm, 133mm. Three heating pipes are arranged side by side.
3. Temperature system: K-type thermocouplewire ;thermocouple wire
diameter of 0.40mm, measuring temperature: 0-1100 ºC. Thermocouple
Accuracy ± 0.5%.
4.The precision of heat difference abouttemperturethermocouple :5%
or 15 ºC
5. Using PLC temperature module to collect the temperature data.
6. The control section: PLC module, real-time displayed temperature
curve is controlled bymicrocomputer, the output report.
7. Heating rate: 5 ºC / min or 3 ºC / min can be set.
8. Touch screen control system: real-time displayed temperature
curve;
9. 1m flat feet and minimum thickness feeler is about 0.03mm,
0.05mm;
10. A set of test software.
12. Heating power: 6kw
13. Temperature measurement: once every 2min collection and
displayed with temperature curve;
14.Responsetime of the thermocouple: <0.5s
15. The precision oftemperture: ± 0.5 ºC
16. The precision of time recorder: 1s/h
18. Flat ruler and feeler gauge: Measuring warpage.
