ISO 12219-5:20 14规定了一种基于腔室的静态顶空型方法，用于测量可能从车辆内部单元部件扩散到驾驶室空气中的挥发性有机化合物（VOCs）、甲醛和其他羰基化合物。腔室排放测试旨在向轿厢内部提供组件级排放的特征排放。它还规定了排放试验箱、试样的制备、蒸汽取样装置的连接和试验条件。该方法对于打算用于车辆的新的汽车内部单元部件有效，并且也可以用于从汽车内部装饰组件或二手车中拆卸下来的汽车内部单元部件。根据测试目的，可以适用一组多单元组件。 如果该方法和小室方法之间的单位组分排放的确证信息（ISO12219-4:20 13)。 VOCs的规定分析方法（ISO 16000-6）适用于测定浓度范围为亚μ g/m3至数mg/m3的VOCs。该方法适用于挥发性范围为n-C6至n-C16的非极性和微极性VOCs的测量。还可以分析一些高挥发性化合物（VVOC）和半挥发性有机化合物（SVOC）（参见ISO 16000-6:20 11的资料性附录D）。 ISO 12219-5:20 14是对现有标准的补充，为第三方测试实验室和制造业提供了一种方法: -就特定VOC排放而言，比较来自组装中的各种单元部件的排放， -评估和分类关于特定VOC排放数据的特定单元组件， -提供特定VOC排放数据以开发和验证基于材料的方法和基于组件的方法之间的相关性， -在开发过程中评估原型、“低排放”单元组件。

ISO 12219-5:2014 specifies a chamber based, static headspace type method for measuring volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds which may diffuse from vehicle interior unit components into the cabin air. The chamber emission test is intended to provide characteristic emission of unit component to car interior of assembly level emission. It also specifies the emission test chamber, preparation of the test specimen, connection of the vapour sampling devices and test conditions. This method is valid for new car interior unit components intended for vehicles, and can also be used for car interior unit components disassembled from assembly of car interior trim or used cars. A set of multi-unit components could be applicable according to the test purpose. A dynamic mode operation of emission chamber could be applied if corroborative information of the unit component emission between this method and small chamber method (ISO12219-4:2013) is desired. The specified analytical procedure for VOCs (ISO 16000-6) is valid for the determination of VOCs ranging in concentration from sub-μg/m³ to several mg/m³. The method is applicable to the measurement of non-polar and slightly polar VOCs ranging in volatility from n-C₆ to n-C₁₆. Some very volatile compounds (VVOC) and semi-volatile organic compounds (SVOC) can also be analysed (see informative Annex D of ISO 16000-6:2011). ISO 12219-5:2014 is complementary to existing standards and provides third party test laboratories and manufacturing industry with an approach for: - comparing emissions from various unit components in assembly with regards to specific VOC emissions, - evaluating and sorting specific unit components regarding specific VOC emissions data, - providing specific VOC emissions data to develop and verify the correlation between a material-based method and an assembly-based method, - evaluating prototype, "low-emission" unit components during development.
