油漆和清漆 挥发性有机化合物（VOC）的测定 顶空注射气相色谱法测定 VOC

[中文适用范围]： 本文件规定了低挥发性有机化合物 (VOC) 涂料及其原材料的取样和测试。特别是，本文件规定了一种气相色谱法，用于在标准条件 (101,325 kPa) 下定量测定 VOC 含量 (即沸点高达 250°C 的有机化合物含量)。它适用于按质量计 0.01% 至 0.1% 之间的 VOC 含量。本文件不适用于 ISO 11890-2 中涵盖的半挥发性有机化合物 (SVOC) 含量的测定。本文件不适用于无法通过气相色谱测定的挥发性有机化合物和挥发性无机化合物。ISO/TR 5601 中描述了确定涂料及其原材料的 VOC 含量和 SVOC 含量的适当方法的程序。 [外文原描述]： This document specifies the sampling and testing of low volatile organic compound (VOC) coating materials and their raw materials. In particular, this document specifies a gas-chromatographic method to quantitatively determine the VOC content (i.e. the content of organic compounds with boiling points up to 250 °C) under standard conditions (101,325 kPa). It is applicable to VOC contents between 0,01 % and 0,1 % by mass. This document does not apply to the determination of the semi-volatile organic compounds (SVOC) content, which is covered in ISO 11890 - 2 . This document does not apply to volatile organic and volatile inorganic compounds that cannot be determined by gas chromatography. The procedure for identifying the appropriate method for the determination of VOC content and the SVOC content of coating materials and their raw materials is described in ISO/TR 5601.
