Fogging

Besides volatile organic compounds (VOC), plastics and other non-metallic materials release semi-volatile organic compounds (FOG).

Such compounds can condense on colder surfaces (e.g. windshields) and lead to a layer that impairs visibility. This effect is also known as window fogging.

As part of the Production Part Approval Process (PPAP), this behavior of materials used in the interior of car cabin can be analyzed and quantified by utilizing the respectively designed fogging test method.
