Fogging Tester for testing of Windscreen Fogging

Determination of windscreen fogging in vehicles

Fogging test is a procedure used to determine the amount of windscreen fogging in vehicles. Fogging contains the remnants of chemicals which are discharged from the interior materials in the vehicle and often get deposited on the interior glass of the vehicle.

Fogging testers are developed to test the fogging characteristics of all the materials utilized in the interior of a vehicle, including the amount of volatile components evaporated from textiles, leather, PVC and other polymeric materials. In addition to international standards, several vehicle manufacturers follow their own standards.

Windscreen Fogging

Fogging occurs mainly on the windscreen in front of the car because of the position of the glass, which makes it colder when compared to the rest of the glass in the vehicle, thus causing the evaporated materials to get condensed on it in a relatively high concentration.

Fogging accumulating on the windscreen needs to be kept at a minimum in order to ensure driving safety and to allow drivers to clearly see through the windscreen.

Fogging Tester, EB 03C

The EB 03 Fogging Tester is an equipment for determination of windscreen fogging in vehicles according to ISO 6452 and SAE J1756.

The instrument has a compact design with both the heating bath and cooling bath integrated in one casing. For cooling of the water bath two models are available:

EB 03C – with a built-in cooling system with Peltier elements.

EB 03 – for connection to tap water of max 18 °C.

To read the results different methods can be used. You can weigh the sample to determine the mass of condensable constituents (gravimetric method). You can also use a gloss meter or a haze meter for the determination of fogging value.

Standards

Meets the requirements for fogging tests, according to ISO 6452, SAE J1756 and other automotive standards.

Temperature range

Heating bath: +40 to +130 °C

Cooling bath: +20 to +80 °C

For using of the gravimetric method you need a 5 decimal balance (ask us for a suitable option) and aluminum foil discs (EB 03.09).

We can offer a gloss meter (HACS-380) and a haze meter (HATH-100) for the determination of fogging value.

Other company-specific methods can also occur.
