International organizations, governmental and non-governm

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The ma

They have attracted attention in recent
21、 years because of their impact on indoor air quality. After homes and workplaces, people spend a lot of time in their vehicles. It is important to determine the material emissions of interior parts and to reduce them to an acceptable level, if required. Therefore it is necessary to obtain comprehens
22、ive and reliable information about the types of organic compounds in the interior air of vehicles and also their concentrations.This part of ISO 12219 outlines a method of measuring the types and levels of VOCs in vehicle cabin air under controlled conditions. It describes requirements for a whole v
23、ehicle test chamber and a test protocol. Measurements are carried out according to ISO 16000-6 (VOCs) and ISO 16000-3 (carbonyl compounds).There are several national test methods available for measuring in-vehicle air quality, e.g. References 23. However, this part of ISO 12219 requires a fixed heat
24、ing radiation system whereas the methods of References 23 define a fixed temperature programme.Before setting a fixed radiation density for heating the test vehicle, several validation measurements were performed (Reference 1).ISO 16000-3, ISO 16000-5,6ISO 16000-6, ISO 16000-9,7ISO 16000-10,8ISO 160
25、00-11,9ISO 16000-24,10ISO 16000-25,11as well as ISO 16017-1 and ISO 16017-212also focus on volatile organic compound (VOC) measurements.

26、e determination of volatile organic compounds in cabin interiorsWARNING It is the responsibility of the user of this part of ISO 12219 to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. National regulations for precautions
27、shall be followed.1 ScopeThis part of ISO 12219 describes and specifies the whole vehicle test chamber, the vapour sampling assembly and the operating conditions for the determination of volatile organic compounds (VOCs), and carbonyl compounds in vehicle cabin air. There are three measurements perf
28、ormed: 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 simulati
29、ng driving after the vehicle has been parked in the sun starting at elevated temperatures (driving mode). For the simulation of the mean sun irradiation, a 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
30、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 TA1)sorbe
31、nt tubes described in ISO 16000-6, which includes VOCs ranging in volatility from n-C6to 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 hi
32、gh performance liquid chromatography (HPLC) with detection by ultraviolet absorption. Formaldehyde and other carbonyl compounds can be determined in the approximate concentration range 1 g/m3to 1 mg/m3.The method is valid for passenger cars, as defined in ISO 3833.This part of ISO 12219 describes:a)
33、 transport and storage of the test vehicles until the start of the test;b) conditioning for 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 (am
34、bient 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).Buses, motor caravans, and trucks, in accordance with the descriptions given in ISO 3833, are excluded.1) Tenax TAis the trade name o
