Automotive interior materials atomization test standard analysis (1) - Huaqiang Electronic Network

Volatile substances in automotive interior materials will condense into fog on the windshield after being volatilized by heat. This condensation phenomenon of volatile substances in the glass interior parts of the car interior is called fogging, also called knotting. The characteristics of fog, the condensate is also called the condensing component. The fogging of automotive interior materials can hinder the view through the windshield, and fogging under adverse lighting conditions can affect the safety of driving. At the same time, since the condensing components are mostly harmful organic volatiles, the fogging level can also reflect the level of organic volatiles in the interior materials. Therefore, automobile manufacturers in developed countries have set limits on the fogging of automotive interior materials. Principle of the test: The sample is placed in a glass beaker under specified conditions and heated, and any volatile material is condensed on a cooled glass plate or a cooled aluminum foil. The atomization performance of the sample is expressed by calculating the atomization value or the atomization amount. In the atomization test standard, the interior materials are different, and the requirements for the atomization test parameters are also different. The following are the specific parameters of several commonly used atomization standards:
