车内空气质量对驾驶员和乘客的健康和舒适度有着重要的影响。车内部件和材料的挥发性有机化合物(VOCs)排放是车内空气污染的主要来源之一。为了保障车内空气质量,需要对车内部件和材料的VOCs排放进行测试和评估。
ISO 12219-4:2013标准提供了一种测量车内部件和材料VOCs排放的方法——小型室内法。该方法使用小型室内测试设备,将待测部件或材料放置在室内,通过恒温、恒湿的条件下,测量室内空气中VOCs的浓度变化,从而计算出部件或材料的VOCs排放量。
该标准规定了测试设备的要求、测试条件、测试程序和数据处理方法。测试设备应具有恒温、恒湿、恒流量等特点,以保证测试结果的准确性和可重复性。测试条件包括温度、湿度、通风等因素,应根据实际使用情况进行选择。测试程序包括样品准备、测试前的预处理、测试过程中的数据采集和测试后的数据处理等步骤。数据处理方法包括计算VOCs排放量、计算排放速率等。
该标准适用于轿车、商用车和其他车辆的内部部件和材料的排放测试。测试的部件和材料包括但不限于座椅、地毯、内饰板、仪表板、门板、顶棚、储物箱等。测试结果可用于评估车内空气质量,指导车内部件和材料的选择和设计,以减少VOCs排放对车内空气质量的影响。
