ISO 12219-2:2012规定了测量挥发性有机化合物（VOCs）、甲醛和其他可能从车辆内部扩散到道路车辆内部空气中的羰基化合物的取样袋试验方法。该方法用于评估和筛选新的车辆内部零件和材料，如座椅、仪表板、天花板材料等。 ISO 12219-2:2012中规定的试验方法规定了使用取样袋筛选挥发性有机化合物、甲醛和其他羰基化合物的程序。 ISO 12219-2:2012为第三方测试实验室和制造业提供了成本- 有效方法:a）在开发过程中评估和筛选原型、“低扩散”材料或产品；b） 比较某一范围内产品的扩散（例如不同的颜色或图案）。 ISO 12219-2:2012规定了用于测试车辆内部部件扩散的气相有机排放物的取样袋的设计、构造、性能、评估和使用。

ISO 12219-2:2012 specifies the sampling bag test method for measuring volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds which may diffuse from vehicle interior parts into the air inside road vehicles. This method is intended for evaluating and screening new vehicle interior parts and materials such as seats, the instrument panel, ceiling materials and so on. The test method specified in ISO 12219-2:2012 specifies a procedure for screening of VOCs, formaldehyde and other carbonyl compounds using sampling bags. ISO 12219-2:2012 provides third party test laboratories and manufacturing industry with a cost-effective approach for: a) evaluating and screening prototype, "low-diffusion" materials or products during development; b) comparing diffusions from products within a range (e.g. different colours or patterns). ISO 12219-2:2012 specifies the design, construction, performance, evaluation, and use of sampling bags for testing vapour-phase organic emissions diffused from vehicle interior parts.
