ISO 1 2219-5 "Air inside road vehicles, Part 5: Screening method for the determination of volatile organic matter emissions from vehicle interior parts and materials, static chamber method" specifies a screening method for the determination of vocs (VOCs) emissions from road vehicle interior parts and materials. This method is tested by static chamber method, which aims to evaluate the impact of vehicle interior materials on the air mass inside the vehicle, especially the release of vocs. The steps such as test procedures, equipment requirements, sample preparation and result evaluation are described in detail in the standard. This method is mainly used to screen and compare the emission levels of different materials, and to provide a reference for car companies to select interior materials that meet environmental protection requirements. The implementation of this standard helps to improve the air mass in vehicles, ensure compliance with relevant environmental regulations, and improve passenger health and comfort.
