It specifies a method for the determination of the volatile o
26、rganic 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 be employed. This method assumes t
27、hat 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. The following referenced documents are indispensable for the application of this document. Fo

32、nd 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 correct usage of the term VOC in the field of coating materials, see volatile or
33、ganic 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 is defined as being an exempt compound. ISO 4618:2006 NOTE 3 Under European leg
34、islation, 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 of the volatile organic compounds present in a coating material, as determined un
35、der 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 and the methods of determination or calculation are stipulated by regulations o
36、r 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 below that limit and compounds with higher boiling points are considered to be non-v
37、olatile 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 accordance with the manufacturers instructions in the correct proportions and thinn
38、ed, 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 3251, and the water content is determined using a titration technique employing Kar
39、l 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. 5 EN ISO 11890-1:2007 (E) 5 Required supplementary information For any particular applicatio
40、n, the test method specified in this part of ISO 11890 shall be completed by supplementary information. The items of supplementary information are given in Annex A. 6 Sampling Take a representative sample of the product to be tested (or of each product in the case of a multi-coat system) as specifie
41、d 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 Number of determinations and general test conditions Carry out all tests in duplicate at (23 2) C and a relative humidity of (50
42、 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. Some may be determined by difference, depending on the compounds present in the sample. 7.3 Density If required by the calcu
43、lation (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 density at 23 C. 7.4 Non-volatile-matter content For single-component products, weigh test portions of the appropriate size (see
44、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 with the manufacturers instructions. Immediately weigh test portions of the appropriate size (see Table 1 in ISO 3251:2003) in
45、to 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 in accordance with ISO 3251. If any unusual decomposition or degradation occurs during heating, periods of time and/or temper
46、atures 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, by the method given in ISO 760, selecting the reagents so that there will be no interference from the compounds contained in
47、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 are ketones and aldehydes. Reagent manufacturers normally publish literature for guidance on correct reagent selection. NOTE 2
48、 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 be zero. 6 EN ISO 11890-1:2007 (E) 7.6 Exempt compounds (only where national legislation applies) 7.6.1 If the organic compou
49、nds contained in the sample are not known, then determine them qualitatively, e.g. by the method specified in ISO 11890-2. 7.6.2 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 method specified in the referring specification.
