ISO 1 2219-1 "Air inside road vehicles - Part 1: Specifications and methods for the determination of vocs in vehicle interior interiors in vehicle laboratories" specifies a standard method for the determination of vocs (VOCs) in road vehicle interior materials by vehicle interior laboratories. The standard details the specifications of laboratory equipment, the control conditions of the interior environment, the steps for sample collection and processing, and the analytical methods for determining vocs. The standard makes it possible to effectively evaluate the air mass performance of interior materials in vehicles during use, especially during the vehicle manufacturing and design stages, to ensure that vehicle interior materials meet health and environment protection requirements. This standard is important for improving the air mass in vehicles and safeguarding consumer health.
