12、International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee
13、 has been established has the right to be represented on that committee. International 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 electrotechnic
14、al standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodi
15、es for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any o
16、r all such patent rights.ISO 12219-2 was prepared by Technical Committee ISO/TC 146, Air quality, Subcommittee SC 6, Indoor air, in collaboration with Technical Committee ISO/TC 22, Road vehicles.ISO 12219 consists of the following parts, under the general title Interior air of road vehicles: Part 1

20、s) are widely used in industry and may be emitted by many everyday products and materials. They have attracted much 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 mate
21、rial emissions of interior parts and 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.This part of ISO 12219 outlines the s
22、ampling bag test method for the screening of VOCs, formaldehyde and other carbonyl compounds which diffuse from vehicle interior parts into the air inside road vehicles.Measuring VOCs from vehicle interior parts can be performed in several ways and the approach selected depends upon the desired outc
23、ome and the material type. For example, to obtain diffusion data from complete assemblies (e.g. instrument panel, seat etc.) it is necessary to employ chambers / bags that have sufficient volume to house the complete assembly. Meanwhile, to obtain diffusion data from representative samples of homoge
24、neous vehicle interior materials, the micro-scale chamber method can be chosen.Each measurement method such as bag/micro-scale chamber/small-chamber sampling offers a complementary approach.ISO 16000-3, ISO 16000-5,2ISO 16000-6, ISO 16000-9,3ISO 16000-10,4ISO 16000-11,5ISO 16000-24,6ISO 16000-25,7as

National regulations for precautions shall be followed.1 ScopeThis part of ISO 12219 specif
27、ies the sampling bag test method for measuring volatile organic compounds (VOCs), formaldehyde and other carbonyl compounds which may diffuse from vehicle interior parts into the air inside road vehicles. This method is intended for evaluating and screening new vehicle interior parts and materials s
28、uch as seats, the instrument panel, ceiling materials and so on.The test method specified in this part of ISO 12219 specifies a procedure for screening of VOCs, formaldehyde and other carbonyl compounds using sampling bags.This part of ISO 12219 provides third party test laboratories and manufacturi
29、ng industry with a cost-effective approach for:a) evaluating and screening prototype, “low-diffusion” materials or products during development;b) comparing diffusions from products within a range (e.g. different colours or patterns).This part of ISO 12219 specifies the design, construction, performa
30、nce, evaluation, and use of sampling bags for testing vapour-phase organic emissions diffused from vehicle interior parts.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

37、TVOCMS), and quantified by converting the total area of the chromatogram in that analytical window to toluene equivalentsNOTE Adapted from ISO 16000-6:2011, 3.4.4 PrincipleThe test method specified in this part of ISO 12219 is a procedure for calculating sampling bag values of VOCs, formaldehyde, an
38、d other carbonyl compounds which may diffuse from vehicle interior parts.One or multiple test specimens put in a sampling bag are heated to a specified temperature, then a fraction of the gas in the sampling bag is collected to measure the test concentrations. By comparing the test concentrations wi
39、th the corresponding blank concentrations, the sampling bag values of VOCs, formaldehyde, and other carbonyl compounds diffusing from one test specimen can be calculated (see Clause 10).The analytical part of the overall measurement procedure is based on the use of sorbent tubes with subsequent ther
40、mal desorption and gas chromatographic analysis for VOCs (according to ISO 16000-6) and the use of 2,4-dinitrophenylhydrazine (DNPH) sorbent tubes, followed by high performance liquid chromatography (HPLC) analysis with ultraviolet absorption for the determination of formaldehyde and other carbonyl
41、compounds (according to ISO 16000-3).The specified analytical procedure is valid for the determination of VOCs ranging in concentration from sub-microgram per metre cubed to several milligrams per metre cubed. The method is applicable to the measurement of non-polar and slightly polar VOCs ranging i
42、n volatility from n-C6to n-C16.The specified analytical procedure for formaldehyde and other carbonyl compounds is valid for the determination of carbonyl compounds within the concentration range of approximately 1 g/m3to 1 mg/m3.5 Apparatus and materials5.1 General. The test apparatus and materials
