24、anic compounds (VOCs) are widely used in industry and may be emitted by many everyday products and materials. They have attracted attention in recent years because of their impact on indoor air quality. After homes and workplaces, people spend a lot of time in their vehicles. Therefore there is a ne

25、ed for comprehensive and reliable information about the types of organic compounds in the interior air of vehicles and also their concentrations. As part of measures to achieve acceptable indoor air quality it is important to determine the material emissions of interior parts and to reduce them, if

26、necessary, to an acceptable level.Measuring VOCs from vehicle interior trim components can be performed in several ways and the approach selected depends upon the desired outcome and the material type. Complete assembly-based measurements1,5provide total emission results only, but cannot provide VOC

27、s emission of each constituent component. Rapid screening methods obtain VOCs emission data for cut components.2,3,6,7Therefore, VOCs emission data for constituent unit component of car interior trim is required for reducing VOCs level in vehicles.This part of ISO 12219 outlines a method of measurin

28、g the types and levels of chemicals emitted by unit component-based car interior trim using a static chamber method based on the principles of static headspace. Static chamber methods can provide diffusion data from unit components of vehicle interior trim without emission from cutting planes. It ca

29、n be used to verify the correlation between a material-based method and an assembly-based method. Adjunctively, the static headspace chamber method is simply modified to the dynamic headspace mode to obtain complementary information by connecting of a supply of air for comparison.Each measurement me

32、ed, static headspace type method for measuring volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds which may diffuse from vehicle interior unit components into the cabin air. The chamber emission test is intended to provide characteristic emission of unit component to car in

33、terior of assembly level emission. It also specifies the emission test chamber, preparation of the test specimen, connection of the vapour sampling devices and test conditions. This method is valid for new car interior unit components intended for vehicles, and can also be used for car interior unit

34、 components disassembled from assembly of car interior trim or used cars. A set of multi-unit components could be applicable according to the test purpose.A dynamic mode operation of emission chamber could be applied if corroborative information of the unit component emission between this method and

35、 small chamber method (ISO 12219-4:2013) is desired.The specified analytical procedure for VOCs (ISO 16000-6) is valid for the determination of VOCs ranging in concentration from sub-g/m3to several mg/m3. The method is applicable to the measurement of non-polar and slightly polar VOCs ranging in vol

36、atility from n-C6to n-C16. Some very volatile compounds (VVOC) and semi-volatile organic compounds (SVOC) can also be analysed (see informative Annex D of ISO 16000-6:2011).This part of ISO 12219 is complementary to existing standards and provides third party test laboratories and manufacturing indu
