本文件描述并规定了用于测定挥发性有机化合物（VOCs；更多信息见附件？E）和车舱空气中的羰基化合物的整车试验箱、蒸汽取样组件和操作条件。进行了三次测量:一次（针对VOCs和羰基化合物）是在23？°C，无空气交换；第二个仅用于在高温下测量甲醛（停车模式）；第三个用于VOCs和羰基化合物，模拟车辆在高温下开始停放在阳光下后的驾驶（驾驶模式）。为了模拟平均太阳辐照，采用整车试验室内的固定辐照。VOC方法适用于测量浓度范围为亚微克/立方米至几毫克/立方米的非极性和微极性VOC。使用该方法中描述的原理，还可以分析一些半挥发性有机化合物（SVOC）。相容化合物是那些可以从Tenax TA中捕获和释放的化合物？1)？ISO中描述的吸附剂管？16000？6，其包括挥发性范围为n-C6至n-C16的VOC。甲醛和其他羰基化合物的取样和分析程序是通过将空气收集到涂有2,4-二硝基苯肼（DNPH）的柱上，然后通过高效液相色谱（HPLC）进行分析，并通过紫外吸收进行检测。甲醛等羰基化合物可在近似浓度范围1？微克/立方米到1？毫克/立方米。此方法适用于ISO中定义的卡车和公共汽车？3833:1977 3.1.1至3.1.6。本文件描述:a)试验车辆的运输和储存，直至试验开始。b)测试车辆的周围环境和测试车辆本身以及整个车辆测试室的调节。c)在测量之前调节测试载体。d)模拟环境空气条件(环境模式)。e)高温下的甲醛取样（停车模式）。f)在测试车辆已经停在阳光下后模拟驾驶(驾驶模式)。1）Tenax？是Buchem提供的产品的商品名。这些信息是为了方便本文件的用户而提供的，并不构成ISO对指定产品的认可。如果能够显示出相同的结果，则可以使用等效产品。
This document describes and specifies the whole vehicle test chamber, the vapour sampling assembly and the operating conditions for the determination of volatile organic compounds (VOCs; for more information see Annex E), and carbonyl compounds in vehicle cabin air. There are three measurements performed: one (for VOCs and carbonyl compounds) during the simulation of ambient conditions (ambient mode) at standard conditions of 23 °C with no air exchange; a second only for the measurement of formaldehyde at elevated temperatures (parking mode); and a third for VOCs and carbonyl compounds simulating driving after the vehicle has been parked in the sun starting at elevated temperatures (driving mode). For the simulation of the mean sun irradiation, fixed irradiation in the whole vehicle test chamber is employed.The VOC method is valid for measurement of non-polar and slightly polar VOCs in a concentration range of sub-micrograms per cubic metre up to several milligrams per cubic metre. Using the principles described in this method, some semi-volatile organic compounds (SVOC) can also be analysed. Compatible compounds are those which can be trapped and released from the Tenax TA？1) sorbent tubes described in ISO 16000？6, which includes VOCs ranging in volatility from n-C6 to n-C16.The sampling and analysis procedure for formaldehyde and other carbonyl compounds is performed by collecting air on to cartridges coated with 2,4-dinitrophenylhydrazine (DNPH) and subsequent analysis by high performance liquid chromatography (HPLC) with detection by ultraviolet absorption. Formaldehyde and other carbonyl compounds can be determined in the approximate concentration range 1 μg/m3 to 1 mg/m3.This method applicable to trucks and buses, as defined in ISO 3833:1977 3.1.1 to 3.1.6.This document describes:a) Transport and storage of the test vehicle until the start of the test.b) Conditioning of the surroundings of the test vehicle and the test vehicle itself as well as the whole vehicle test chamber.c) Conditioning of the test vehicle prior to measurements.d) Simulation of ambient air conditions (ambient mode).e) Formaldehyde sampling at elevated temperatures (parking mode).f) Simulation of driving after the test vehicle has been parked in the sun (driving mode).1)Tenax TA？ is the trade name of a product supplied by Buchem.
