12、hy . 9 BS EN ISO 11890-1:2007ISO 11890-1:2007(E) iv ISO 2007 All rights reservedForeword ISO (the 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
13、ISO technical committees. Each member body interested in a subject for which a technical committee 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
14、 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical 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.
15、 Draft International Standards adopted by the technical committees are circulated to the member bodies 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
16、document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11890-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes. This second edition cancels and replaces the first edition (ISO 11890-1:2000), which has bee
17、n technically revised. The main change is that, in order to allow the method to be used for multi-component systems as well as single-component systems, the test portion preparation procedures for the determination of the non-volatile-matter content of each of these two types of system has been incl
18、uded in Subclause 7.4. ISO 11890 consists of the following parts, under the general title Paints and varnishes Determination of volatile organic compound (VOC) content: Part 1: Difference method Part 2: Gas-chromatographic method BS EN ISO 11890-1:2007INTERNATIONAL STANDARD ISO 11890-1:2007(E) ISO 2
19、007 All rights reserved 1Paints and varnishes Determination of volatile organic compound (VOC) content Part 1: Difference method 1 Scope This 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 t
20、he determination of the volatile organic compound (VOC) content of paints, varnishes and their raw materials. This part may be used where the expected VOC content is greater than 15 % by mass. When the expected VOC content is greater than 0,1 % by mass and less than 15 % by mass, ISO 11890-2 should
21、be employed. This method assumes that 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 references The following referenced documents a

26、3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 volatile organic compound VOC any organic liquid and/or solid that evaporates spontaneously at the prevailing temperature and pressure of the atmosphere with which it is in contact NOTE 1 As to
27、correct usage of the term VOC in the field of coating materials, see volatile organic compound content (VOC content). NOTE 2 Under U.S. government legislation, the term VOC is restricted solely to those compounds that are photochemically active in the atmosphere (see ASTM D 3960). Any other compound
28、 is defined as being an exempt compound. ISO 4618:2006 NOTE 3 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. 3.2 volatile organic compound content VOC content mass o
29、f the volatile organic compounds present in a coating material, as determined under specified conditions NOTE 1 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
30、 and the methods of determination or calculation are stipulated by regulations or by agreement. ISO 4618:2006 NOTE 2 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 belo
31、w that limit and compounds with higher boiling points are considered to be non-volatile organic compounds. 3.3 exempt compound organic compound that does not participate in atmospheric photochemical reactions NOTE See Notes 2 and 3 to 3.1. 3.4 ready for use state of a product when it is mixed in acc
32、ordance 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 method 4 Principle After preparation of the sample, the non-volatile matter content is determined in accordance with ISO 325
33、1, and the water content is determined using a titration technique employing Karl Fischer reagent in accordance with ISO 760. The contents of exempt compounds, if applicable, are then determined using the method specified in ISO 11890-2. The VOC content of the sample is then calculated. BS EN ISO 11

The items of supplementary information are given in Annex A. 6 Samplin
35、g Take a representative sample of the product to be tested (or of each product in the case of a multi-coat system) as specified in ISO 15528. Examine and prepare each sample for testing, as specified in ISO 1513, preparing the final sample for testing in the “ready for use” state. 7 Procedure 7.1 Nu
36、mber of determinations and general test conditions Carry out all tests in duplicate at (23 2) C and a relative humidity of (50 5) % unless otherwise agreed (see ISO 3270). 7.2 Determination of parameters Determine the parameters required by the calculation (see 8.2 to 8.5) as specified in 7.3 to 7.6
37、. Some may be determined by difference, depending on the compounds present in the sample. 7.3 Density If required by the calculation (see 8.3 to 8.5), determine the density of the sample using the part of ISO 2811 which will give the best precision for the type of sample concerned. Determine the den
38、sity at 23 C. 7.4 Non-volatile-matter content For single-component products, weigh test portions of the appropriate size (see Table 1 in ISO 3251:2003) into dishes as specified in ISO 3251. Proceed in accordance with ISO 3251. For multi-component systems, thoroughly mix the components in accordance
39、with the manufacturers instructions. Immediately weigh test portions of the appropriate size (see Table 1 in ISO 3251:2003) into dishes as specified in ISO 3251. Allow the test portions to stand in the dishes for 1 h at (23 2) C and atmospheric pressure. Then place the dishes in the oven and proceed
40、 in accordance with ISO 3251. If any unusual decomposition or degradation occurs during heating, periods of time and/or temperatures different from those given in ISO 3251 may be used by agreement between the interested parties. 7.5 Water content Determine the water content, as a percentage by mass,
41、 by the method given in ISO 760, selecting the reagents so that there will be no interference from the compounds contained in the sample. If the compounds are not known, then determine them qualitatively, e.g. by the method given in ISO 11890-2. NOTE 1 Typical compounds likely to cause interference
42、are ketones and aldehydes. Reagent manufacturers normally publish literature for guidance on correct reagent selection. NOTE 2 If the product to be tested is well characterized and known not to contain water, it is not necessary to determine the water content, and the water content can be assumed to
43、 be zero. BS EN ISO 11890-1:2007ISO 11890-1:2007(E) 4 ISO 2007 All rights reserved7.6 Exempt compounds (only where national legislation applies) 7.6.1 If the organic compounds contained in the sample are not known, then determine them qualitatively, e.g. by the method specified in ISO 11890-2. 7.6.2
44、 Determine the contents of the exempt compounds contained in the sample using the method specified in ISO 11890-2. 7.6.3 Determine the densities of the exempt compounds by the method given in 7.3, or by referring to published reference data. 8 Calculation 8.1 General Calculate the VOC content by the
45、 method specified in the referring specification. If no particular method is specified, calculate the VOC content by method 1. Method 1 is the preferred calculation method as the precision is better since it does not involve the determination of density, which introduces the potential for additional
46、 errors. 8.2 Method 1: VOC content, as a percentage by mass, of the product “ready for use” wVOC 100 NV w= (1) where VOC is the VOC content, as a percentage by mass, of the product “ready for use”; NV is the non-volatile-matter content, as a percentage by mass (see 7.4); wwis the water content, as a
