Volatile substances found in automotive interior materials can form fog on the windshield after being released into the air due to heat. This phenomenon, known as "fogging," occurs when volatile components condense on the inside of the glass. The condensed material is referred to as the "condensing component." Fogging can impair visibility through the windshield and may pose a safety risk, especially under poor lighting conditions. Moreover, these condensing components are often harmful organic compounds, so the level of fogging can serve as an indicator of the amount of volatile organic compounds present in the materials. As a result, many automobile manufacturers in developed countries have established specific limits for fogging levels in interior materials.

The testing method involves placing a sample in a glass beaker under controlled conditions and heating it. Any volatile substances will then condense on a cooled glass plate or aluminum foil. The atomization performance is measured by calculating the atomization value or the amount of condensate. Different standards exist for various interior materials, and each may have distinct parameters for the atomization test. Here are some common standards and their specific requirements:
