The work of preparing Int
25、ernational 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 w
26、ith 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 techni
27、cal 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
28、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 17895 was prepared by Technical Committee ISO/TC 35, Paints and varnishes. ENISO17895:2005IS:59871 O5002(E) I SO 500
29、2 All irthgs ersedevr vIntroduction The requirements imposed today by authorities, for health and environmental reasons, include the assessment of the content of residual monomers and organic saturated volatiles, sometimes down to minute traces. This International Standard is one of a series of stan
30、dards dealing with the VOC content of paints, varnishes and related products: ISO 11890-1 (see the Bibliography) specifies a method for determining VOC contents greater than 15 % (by mass), ISO 11890-2 is applicable to VOC contents between 0,1 % and 15 % (by mass). This International Standard descri
31、bes a method for determining VOC contents between 0,01 % and 0,1 % (by mass). In contrast to ISO 11890-1 and ISO 11890-2, this standard is applicable to volatile organic compounds with boiling points up to 250 C.

The method is applicable to VOC contents between 0,01 % and 0,1 % (by mass). The main purpose of the method is to qualify low-VOC emulsion paints, not rou

38、 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 then defined as being an exempt compound. ISO 4618 ENISO17895:2005IS:59871 O5002(E) 2 I SO

The peak areas of all the components with retention times less than that of

NOTE Determination of individual components in the sample, or of standards prepared separately from emulsions or emulsion paints which are as free of VOCs as possible, can be used to validate the analytical system. 5 Apparatus Ordinary laboratory apparatus and glassware, together with the following: 5.1 Gas chromatography system, consisting of a headspace injector, preferably with an automati
