道路车辆内空气 第4部分 来自车辆内装品和材料的挥发性有机化合物释放的测定方法 小室法

[中文适用范围]： ISO 12219 的本部分规定了在模拟真实使用条件下，使用小型排放测试室（小型室）对汽车内饰材料释放的气相有机化合物（挥发性和一些半挥发性）进行定性和定量分析的方法。小型室旨在提供车辆级排放的传递函数。该方法旨在评估新车内饰部件，但原则上也可以应用于二手车部件。目标化合物包括 VOC（传统上定义为挥发性范围为 Ph-己烷至 Ph-十六烷的有机化合物）和挥发性羰基化合物，如甲醛。VOC 的规定分析程序为 ISO 16000-6，甲醛和一些其他轻质羰基化合物的规定分析程序为 ISO 16000-3。注：也可以分析比 pn-己烷挥发性更强和比 np-十六烷挥发性更弱的化合物 [见 ISO 12219 的本部分与 ASTM D5116 和 VDA 276 互补，并提供了第三方标准。该方法可帮助测试实验室和制造业：a) 确定实际使用条件对特定挥发性有机化合物 (VOC) 排放数据的影响；b) 比较不同组件的特定挥发性有机化合物 (VOC) 排放；c) 评估和分类特定组件的特定挥发性有机化合物 (VOC) 排放数据；d) 提供特定挥发性有机化合物 (VOC) 排放数据以建立并验证材料级方法与车辆级方法之间的相关性；e) 在开发过程中评估原型“低排放”组件。 [外文原描述]： ISO 12219-4:2013 specifies a qualitative and quantitative analytical method for vapour-phase organic compounds (volatile and some semi-volatile) released from car trim materials under simulated real use conditions using small emission test chambers (small chamber). Small chambers are intended to provide a transfer function to vehicle level emissions. This method is intended for evaluating new car interior trim components but can, in principle, be applied to used car components. Target compounds include VOCs (conventionally defined as organic compounds in the volatility range n-hexane to n-hexadecane) and volatile carbonyl compounds such as formaldehyde. The specified analytical procedure for VOCs is ISO 16000‑6 and for formaldehyde and some other light carbonyl compounds is ISO 16000‑3. ISO 12219-4:2013 is complementary to ASTM D5116 and VDA 276, and provides third party test laboratories and manufacturing industry with an approach for: a) identifying the effect of real use conditions on specific VOC emissions data; b) comparing emissions from various assemblies with regards to specific VOC emissions; c) evaluating and sorting specific assemblies regarding specific VOC emissions data; d) providing specific VOC emissions data to develop and verify a correlation between material level methods and the vehicle level method; e) evaluating prototype, "low-emission" assemblies during development.
