The thermal radiation drop tester is developed according to the French building material and railway vehicle flame retardant test standard NF P92-505, and meets the requirements of the European Union 95/28/EC automobile interior material fire test standard. The principle of the test is that the sample is subjected to 30KW/m2 thermal radiation .Absolute thermal resistance is the temperature difference across a structure when a unit of heat energy flows through it in unit time.It is the reciprocal of thermal conductance.The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals are equal: ΔT = 1 K = 1 °C.The so-called bolometer is a special type of thermal detector and is based on the temperature-dependence of an electrical resistance. The sensitive detector element comprises a resistor, whose value changes when heat radiation is absorbed. The change in resistance causes a change in the signal voltage drop across the bolometer resistance.
Photons carry the radiation energy. The photons travel until they are absorbed by another substance, making the latter feel warm. Thermal radiation does not require any medium to propagate and can travel through a vacuum. This property makes thermal radiation unique compared to conduction and convection. However, it can be dangerous because the .

The so-called bolometer is a special type of thermal detector and is based on the temperature-dependence of an electrical resistance. The sensitive detector element comprises a resistor, whose value changes when heat radiation is absorbed. The change in resistance causes a change in the signal voltage drop across the bolometer resistance.
Since 1990 radiation thermometers, whose operation is based on Planck's law of thermal radiation, have been used to establish the temperature scale above 961.78°C using the freezing point of silver, gold, or copper as a reference temperature according to the International Temperature Scale of 1990 (ITS-90) [11], [12], [13].In addition, because radiation thermometry .

Thermal Radiation Effects Testing. The majority of thermal radiation effects testing is performed with high intensity flash lamps, solar furnaces, or rocket nozzles using liquid oxygen and powdered aluminum, called a thermal radiation source (TRS). . Machines such as hammers, drop towers, and slapper plates are used for simulating shock .A black body is an idealized object that absorbs all of the thermal radiation that falls on it, and emits thermal radiation with a spectrum that depends only on its temperature. It is often used as a theoretical model to describe the behavior of thermal radiation.
Thermal radiation is ubiquitous in nature. Any object with non-zero temperature can emit and absorb thermal radiation. In recent decades, drawing from in-depth studies of nano-optics and .
