BS ISO 12219-9:2019标准是一项关于内饰空气中挥发性有机化合物排放的测量方法的标准。该标准采用大袋法进行测量，适用于轻型汽车、货车和客车等道路车辆的内饰空气中挥发性有机化合物的测量。

内饰空气中的挥发性有机化合物是指在车内使用过程中，由车内材料和装饰物所释放出的有机化合物。这些有机化合物对人体健康有一定的影响，因此需要对其进行测量和控制。BS ISO 12219-9:2019标准提供了一种测量内饰空气中挥发性有机化合物排放的方法，以便对其进行控制。

该标准采用大袋法进行测量，即将车内空气收集到一个大袋中，然后对袋内空气中的挥发性有机化合物进行分析。该方法具有简单、快速、准确的特点，可以有效地测量内饰空气中的挥发性有机化合物排放。

BS ISO 12219-9:2019标准适用于轻型汽车、货车和客车等道路车辆的内饰空气中挥发性有机化合物的测量。该标准的实施可以帮助车辆制造商和相关部门控制车内空气中的有害物质排放，保障人们的健康和安全。
