Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internat

16、ional organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intende

17、d for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

ISO 2017 All rights reserved vBS ISO 12219-6:2017ISO 12219-6:2017(E)IntroductionVolatile and semi-volatile organic compounds (VOCs and SVOCs) are widely used in industr

22、y and can 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. It is important to determine the material emissions of interior parts a

23、nd to reduce them to an acceptable level, if required. Therefore, it is necessary to obtain comprehensive and reliable information about the types of organic compounds in the interior air of vehicles and also their concentrations.Monitoring emissions from vehicle trim components can be performed in

24、several ways and the approach selected depends upon the desired outcome and the material type. For example, to obtain emissions data from complete assemblies (e.g. a dashboard or seat), it is necessary to employ emission chambers or bags that have sufficient volume to house the complete assembly (ty

25、pically 1 m3). The performance of such tests may take several hours or even days, depending on specified equilibration times and the requirements of the relevant test protocol.This document outlines a screening method for measuring the types and levels of VOCs and SVOCs in vehicle trim components un

26、der controlled conditions using a small emission test chamber (small chamber). The described screening method can be used to investigate the emissions of car interior trim under conditions of real use where elevated temperatures are prevailing in the cabin of road vehicles. For this purpose, tests a

27、re performed at 65 C and 100 C. ISO 12219-6 describes requirements for a small chamber and a test protocol. Measurements are carried out according to ISO 16000-6 (VOCs).The capacity of a small chamber is not limited to small assemblies or representative test specimens of homogeneous car trim materia

28、ls. Small chambers allow qualitative and quantitative VOC and SVOC emission data to be measured and recorded. The subsequent emission data can be used to develop a correlation between material level methods and the vehicle level method.This document is based on VDA 2762and correlates to ISO 16000-9.

29、Besides the ISO 12219-series, there are parts of ISO 16000 which deal with the measurements of vapour-phase organic chemicals and vapour-phase chemical emissions: Part 3: Determination of formaldehyde and other carbonyl compounds in indoor air and test chamber air Active sampling method Part 5: Samp

34、G This method is unsuitable for materials that are not stable at 100 C in air. Application of this document for thermally unstable materials could lead to irreversible contamination of the test equipment.1 ScopeThis document describes a qualitative and quantitative analytical method for vapour-phase

35、 organic compounds released from car trim materials under simulated real use conditions, i.e. a vehicle is parked for several hours in direct sunlight. Under these conditions, some interior parts and materials reach higher temperatures than 65 C (ISO 12219-4), e.g. a dashboard can reach temperatures

36、 up to 120 C. This document can be implemented as an optional addition to ISO 12219-4 so that VOC, volatile carbonyl and SVOC testing can all be completed within one day. This part has been added to gain insight into the emission behaviour and emission potential of selected vehicle interior parts an

37、d materials exposed to higher temperatures. (By convention, 100 C is set as the higher temperature.) The test is performed in small emission test chambers (small chambers). These small chambers are intended to provide a transfer function for vehicle level emissions. This method is intended for evalu

38、ating new car interior trim components but can, in principle, be applied to used car components.The specified analytical procedure for SVOCs and semi-volatile carbonyls is ISO 16000-6.This document is complementary to existing standards1,2and provides third party test laboratories and manufacturing

39、industry with an approach for identifying the effect of real use conditions on specific VOC and SVOC emissions data, comparing emissions from various assemblies with regards to specific VOC and SVOC emissions, evaluating and sorting specific assemblies regarding specific VOC and SVOC emissions data,

40、 providing specific VOC and SVOC emissions data to develop and verify a correlation between component level methods and in vehicle air quality and evaluating prototype, “low-emission” assemblies during development.The method described can be exclusively performed as a high temperature test or it can

41、 be performed in combination with the determination of VOCs at 65 C in one run, which is described in ISO 12219-4.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
