fogging test equipment

Fogging tester is used to determine the windscreen fogging according to ISO, DIN, ASTM and other automotive standards. The equipment has a compact design with the heating bath and cooling bath integrated in one casing. For cooling the water bath, the instrument is normally connected to tap water of max 18 °C. If the tap water is too warm, a model EB 03C can be supplied with a built in cooling system with Peltier elements.
Working Principle:
The main frame of the tester includes a water sink fully filled with specified ethylene glycol, which can reach a high temperature. At the time of testing, leather specimens are put in the six standard glass containers filled with high temperature liquid, and the stainless steel containers are placed above each glass. Relying on the constant water flow distribution, the temperature can maintain at 20℃ constantly, and it can be adjusted through the regulation device connected to the main frame. This controlled environment condition will generate a layer of “fog” on the surface of specimens. The operator can determine the fogging characteristics of materials based on gravimetric analysis method or refraction method.
Test Methods:
It applies to the following test methods:
1) Gloss Method: the sample cup is heated by the fog evaporated gas condensing on cold glass by glass gloss values were compared before and after condensation and calculated, the sample can be drawn into the fog value.
2) Gravimetric method: the sample cup is heated by the fog evaporated gas condensing on cold aluminum foil, aluminum foil condensed by weighing before and after the change in weight, the sample can be drawn from the atomization - the weight of condensate.
3) Haze method: the sample cup is heated by the fog evaporated gas condensing on cold glass, through the haze value before and after the glass condensate compare and calculate, the sample can be drawn into the fog value.
