Summary	This standard is related to Paints, varnishes and related products, sampling and testing a series of criteria. This standard specifies the determination of paints, varnishes and their raw materials of volatile organic compounds (VOC) content method is mainly applied to the VOC content greater than 15% (mass fraction) of the sample. When the expected VOC content greater than 0. 1 % (mass fraction) and less than 15% (mass fraction), should be used GB/T 23986. This method assumes that the water or organic volatiles. If other volatile inorganic compounds, by other suitable methods to quantitatively measured and deducted considered in the calculation.
