本文件规定了一种大袋取样方法，用于测量挥发性有机化合物（VOCs）、甲醛和其他羰基化合物，这些化合物是从车辆内部零件排放到道路车辆内部空气中的。本方法适用于大型新车内部零件和完整总成的评估。这是一种筛选方法，用于在常规基础上比较相似试验条件下的相似汽车部件。 评价车辆内部部件的VOC排放是车辆室内空气质量的一个重要方面。 本文件是对现有标准的补充，为测试实验室和制造业提供了对车辆内部零件的成本效益评估。此方法仅适用于新制造的车辆零件。该方法适用于所有类型的车辆，以及用作车辆内部零件的车辆产品。

This document specifies a large bag sampling method for measuring volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds which are emitted from vehicle interior parts into the air inside road vehicles. This method is intended for evaluation of large new vehicle interior parts, and complete assemblies. This is a screening method to compare similar car components under similar test conditions on a routine basis. Evaluating VOC emissions of vehicle interior parts is an important aspect of the vehicle indoor air quality. This document is complementary to existing standards and provides test laboratories and the manufacturing industry with a cost-effective evaluation of vehicle interior parts. This method is only applicable to newly manufactured vehicle parts. This method is applicable to all types of vehicles, and vehicle products which are used as parts in the interior of vehicles.
