Project Introduction

Fogging/condensate (fogging/condensate) is the condensation of volatile substances discharged from automotive interior parts and materials on the glass. Automotive interior decoration materials such as leather, plastics, textiles, and adhesives for bonding materials all contain some volatile substances. Especially when the temperature of the car is increased under the sunlight, this volatility will be exacerbated. Volatile gas condenses on car windows or windshields, causing poor vision, which can affect the driver’s sight and driving safety; some volatile substances can affect the driver’s health. In order to reasonably control the generation of volatile substances, it is necessary to conduct atomization tests on materials used in automotive interiors. Materials whose fogging value exceeds the standard index will not be used in automotive interiors.

Applicable product range

The atomization test is suitable for the evaluation of the interior materials of automobiles and aircrafts, such as automotive interior plastic parts, polyurethane, textiles, leather, adhesives, non-woven fabrics, thermoplastic elastomers, etc., at high temperature. It can also be used to measure the high temperature atomization phenomenon of the argon lamp in front of the vehicle.

Detection method

At present, there are many international and domestic fogging test standards for automotive interior materials. These standards involve three test methods: gloss method, weight method, and haze method.

Gloss method: The gas evaporated by heating the sample in the fog cup is condensed on a low-temperature glass plate. By comparing and calculating the gloss value before and after condensation on the glass plate, the fog value of the sample can be obtained.

Haze method: The gas evaporated by heating the sample in the fog cup is condensed on a low-temperature glass plate. By comparing and calculating the haze value before and after condensation on the glass plate, the haze value of the sample can be obtained.

Gravimetric method: The gas evaporated by heating the sample in the fog cup is condensed on the low-temperature aluminum foil. The weight of the sample atomized-condensate can be obtained by weighing the weight change of the aluminum foil before and after condensation.

Standard reference

In the 1970s, some large automobile factories in Europe have begun to study the fogging characteristics of automotive interior parts. In the early 1980s, the German Automobile Standard Drafting Committee and the Synthetic Material Standard Drafting Committee jointly formed the "Fogging" working group. The test method and the reproducibility of the method were systematically studied, and the corresponding standard DIN75201 "Determination of the windscreen fogging characteristics of trimmaterials in motor vehicles" was published in 1992.

Subsequently, the American Association of Motor Vehicle Engineers and the International Organization for Standardization carried out partial revisions on the basis of DIN75201 and promulgated relevant standards ISO 6452 and SAE J1756. According to the above standards, major automobile manufacturers in the world have promulgated enterprise standards for the determination of fogging, and put forward relevant requirements for the fogging characteristics of automotive interior parts.

The various standards and the test methods involved are shown in the table below
