22、zation 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 has been establishe
23、d 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 electrotechnical standardization.I
24、nternational 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 bodies for voting. Publi
25、cation 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 or all such patent ri

28、ganic compound (VOC) content Part 2: Gas-chromatographic method1 ScopeThis part of ISO 11890 is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.It specifies a method for the determination of the volatile organic compound (VOC) content of p
29、aints, varnishes and their raw materials. This part is preferred if the expected VOC content is greater than 0,1 % by mass and less than about 15 % by mass. When the VOC content is greater than about 15 % by mass, the less complicated method given in ISO 11890-1 may be used.This method assumes that
30、the volatile matter is either water or organic. However, other volatile inorganic compounds can be present and might need to be quantified by another suitable method and allowed for in the calculations.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in

34、ganic compoundVOCany organic liquid and/or solid that evaporates spontaneously at the prevailing temperature and pressure of the atmosphere with which it is in contactNote 1 to entry: As to current usage of the term VOC in the field of coating materials, see volatile organic compound content (VOC co

Any othe
36、r compound is then defined as being an exempt compound.Note 3 to entry: Under European legislation, EU Directive 2004/42/EC, the term VOC refers to volatile organic compounds with boiling points up to 250 C, measured at a standard pressure of 101,3 kPa.SOURCE: ISO 4618:2006, modified Note 3 to entry

38、on of the coating material. For each field of application, the limiting values and the methods of determination or calculation are stipulated by regulations or by agreement.Note 2 to entry: If the term VOC refers to compounds with a defined maximum boiling point (see Note 3 to 3.1), the compounds co
39、nsidered to be part of the VOC content are those with boiling points below that limit, and compounds with higher boiling points are considered to be non-volatile organic compounds.SOURCE: ISO 4618:2006, modified Note 2 to entry has been added.3.3exempt compoundorganic compound that does not particip

41、ready for application by the approved method4 PrincipleAfter preparation of the sample, the VOCs are separated by a gas-chromatographic technique. Either a hot or a cold sample injection system is used, depending on the sample type. Hot injection is the preferred method. After the compounds have bee
42、n identified, they are quantified from the peak areas using an internal standard. Depending on the equipment used, it might also be possible to determine the water content by this method. A calculation is then performed to give the VOC content of the sample.5 Required supplementary informationFor an
43、y particular application, the test method specified in this part of ISO 11890 needs to be completed by supplementary information. The items of supplementary information are given in Annex A.6 Apparatus6.1 Gas chromatographThe apparatus shall be set up and used in accordance with the manufacturers in
44、structions. All of the instrumental parts coming into contact with the test sample shall be made of a material (e.g. glass) which is resistant to the sample and will not change it chemically.2 ISO 2013 All rights reservedBS EN ISO 11890-2:2013ISO 11890-2:2013(E)6.2 Sample injection system6.2.1 Gener

The injection temperature shall be capable of being set to an accuracy of 1 C. The split
46、ratio shall be adjustable and capable of being monitored. The sample splitter insert shall contain silanized glass wool to retain non-volatile constituents, and shall be cleaned and provided with new glass wool packing or replaced as required to rule out errors due to residues of binder or pigment (
47、i.e. adsorption of compounds). The occurrence of adsorption is revealed by peak tailing, in particular with components of low volatility.6.2.3 Cold-injection system with sample splitterThe cold-injection system shall be provided with temperature programming for heating from ambient to 300 C and shal
48、l have a sample splitter inlet which is made of an inert material such as glass. The sample splitter shall be provided with silanized glass wool packing and shall be maintained as specified in 6.2.2. The split ratio shall be adjustable and capable of being monitored.Method precision will be increase
49、d if the injection system, especially the hot-injection system, is coupled to an auto-injector. The manufacturers instructions shall be followed when an auto-injector is used.6.2.4 Selection of sample injection systemThe choice between hot-injection and cold-injection will depend on the type of product under test. It will be necessary to use the cold-injection system for products which, at high temperature, release substances which interfere with the determination.Indications of cleavage or decomposition reactions can
