The following terms and definitions apply to this document.
3.1
Black box blackbox
Is a black box is painted black closed rectangular metal box, which is filled with air.
3.2
Blackboard thermometer blackpanelthermometer
A temperature measuring device detecting unit consists of black painted anti-aging coated stainless steel plate and platinum thermocouples, painted black anti-aging
Of coated stainless steel plate during the test can absorb most of the radiation energy, platinum thermocouple for measuring the stainless steel plate.
Its value can be used to estimate the maximum temperature during natural or artificial exposure to the sample can be achieved.
