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 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 about 15 % (by mass). When the expected VOC content is greater than 0,1 % (by mass) and less than about 15 % (by mass), ISO 11890-2 shall be employed.This method assumes that volatile matter is either water or organic. However, other volatile inorganiccompounds may be present and may need to be quantified by another suitable
