4 Foreword 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 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 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. 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 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO was prepared by Technical Committee ISO/TC 35, Paints and varnishes. This second edition cancels and replaces the first edition (ISO :2000), which has been 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 nonvolatile-matter content of each of these two types of system has been included in Subclause 7.4. ISO 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 iv ISO 2007 All rights reserved
5 INTERNATIONAL STANDARD ISO :2007(E) Paints and varnishes Determination of volatile organic compound (VOC) content Part 1: Difference method 1 Scope This part of ISO 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 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 should 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 are indispensable for the application of this document.
