ISO 8142 Thermal Insulation Materials
Maximum Use Temperature Test Apparatus
Introduction:
This maximun use temperature test apparatus is designed
according to ISO 8142: 1990 ,which is used to evaluate the
maximum operating temperature of loose-fill insulation materials,
carpets, blankets, blocks, plates, prefabricated pipe insulation
and some insulation products.
The maximun use temperature test apparatus adopts CNC
machine processing molding. circular modelling is beautiful and
generous.Other parts use 45 # steel,and the surface plating uses
SUS304 stainless steel.
Standard:
- ASTM C411-82 "hot surface temperature insulation performance test
method"
- ASTM C447-85 "insulation maximum use temperature assessment
methods."
- ISO 8142: 1990 Appendix A "pre-determined maximum use of mineral
wool pipe shell temperature of the test method."
Technical parameters:
1. Heating plate: the heating plate is made of SUS304 stainless
steel.the test area is about 900 * 450mm, which is surrounded by
80mm wide protective layer. At least five thermocouples which is
ued to 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 thermocouple wire ;thermocouple wire
diameter of 0.40mm, measuring temperature: 0-1100 ºC. Thermocouple
Accuracy ± 0.5%.
4.The precision of heat difference about temperture thermocouple
:5% or 15 ºC
5. The maximun use temperature test apparatus uses PLC
temperature module to collect the temperature data.
6. The control section: PLC module, real-time displayed temperature
curve is controlled by micro computer, the output report.
7. Two sample canisters are supplied with ISO 8142 Thermal Insulation
Materials Maximum Use Temperature Test Apparatus.
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 is supplied with maximun
use temperature test apparatus.
11. Flat ruler and feeler gauge: Measuring warpage.
