29、890-2:2013 (E) 1 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 paints, varnishes and their raw materials. This p
30、art 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 the volatile matter is either water or organic.
31、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 this document and are indispensable for its appl

35、 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 content).4DIN EN ISO 11890-2:2013-07EN ISO 11890-2
36、:2013 (E) Note 2 to entry: Under US government legislation, the term VOC is restricted solely to those compounds that are photochemically active in the atmosphere (see ASTM D3960). Any other compound is then defined as being an exempt compound.Note 3 to entry: Under European legislation, EU Directiv
37、e 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 has been added.3.2volatile organic compound contentVOC contentmass of the volatile organic compounds present i
38、n a coating material, as determined under specified conditionsNote 1 to entry: The properties and the amounts of the compounds to be taken into account will depend on the field of application of the coating material. For each field of application, the limiting values and the methods of determination
39、 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 considered to be part of the VOC content are those with boiling points below that limit, and compounds with highe
40、r 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 participate in atmospheric photochemical reactionsNote 1 to entry: See Note 2 to entry and Note 3 to entry in 3.1)3.4re
41、ady for usestate of a product when it is mixed in accordance with the manufacturers instructions in the correct proportions and thinned if required using the correct thinners so that it is ready for application by the approved method4 PrincipleAfter preparation of the sample, the VOCs are separated
42、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 been identified, they are quantified from the peak areas using an internal standard. Depending on the equipment us
43、ed, 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 any particular application, the test method specified in this part of ISO 11890 needs to be completed by suppleme
44、ntary 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 instructions. All of the instrumental parts coming into contact with the test sample shall be made of a material
45、(e.g. glass) which is resistant to the sample and will not change it chemically.5DIN EN ISO 11890-2:2013-07 EN ISO 11890-2:2013 (E) 6.2 Sample injection system6.2.1 GeneralUse one of the two types specified in 6.2.2 and 6.2.3.6.2.2 Hot-injection system with sample splitter (preferred system)The inst
46、rument shall have a variable-temperature injection block with a sample splitter. The injection temperature shall be capable of being set to an accuracy of 1 C. The split ratio shall be adjustable and capable of being monitored. The sample splitter insert shall contain silanized glass wool to retain
47、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 (i.e. adsorption of compounds). The occurrence of adsorption is revealed by peak tailing, in particular with components of low vola

The sample splitter shall be provided with silani
49、zed 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 increased 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-in
