标准范围

本文件是ISO 11890系列的一部分，涉及涂料及其原材料的取样和测试。本文件适用于下列情况下挥发性有机化合物（VOC）含量的测定:—？案例1:除案例3外还有单包涂料，且预计VOC含量大于质量分数5的地方？%，包括不通过化学反应固化的单包装涂料和由于化学固化反应或气相色谱温度导致形成在正常固化条件下不会出现的新化合物而无法通过ISO 11890-2测量的单包装涂料，并影响VOC/SVOC计算；—？案例2:除了案例3之外，还有多包涂料，并且预期VOC含量大于质量分数1？%;—？案例3:哪里有辐射固化涂料，且预计VOC含量大于质量分数5？%.本文中的可辐射固化涂层材料包括通过UV、电子束和其他辐射方法固化的涂层材料。如果第一种情况的系统含有SVOC，但不通过化学反应固化，则VOC结果可能会受到SVOC的影响，见附件？C.在这种情况下，ISO 11890-2是优选的。ISO 11890-1不能用于SVOC含量的测定。在不通过化学反应固化的水性涂料材料中，如果含水量远大于VOC含量且VOC含量小于质量分数10？%，优选ISO 11890-2。对于所有三种情况，测量的主要目的是VOC。但是，请澄清该VOC含量也可以包含SVOC。真实的VOC含量可以低于ISO测得的VOC含量？11890-1.本文件中规定的方法假设挥发物是水或有机物。然而，可能存在其他挥发性无机化合物，其可能需要另一种合适的定量方法，因此在计算中允许。本文件中定义的方法不适用于水分测定。

This document is part of the ISO 11890 series, dealing with the sampling and testing of coating materials and their raw materials.

This document is applicable to the determination of volatile organic compound (VOC) content in the following cases:

—     case 1: where there are single-pack coating materials other than case 3, and the expected VOC content is greater than a mass fraction of 5 %, including single-pack coating materials cure not through chemical reactions and single-pack coating materials which cannot be measured by ISO 11890-2 due to chemical cure reactions or gas chromatography temperatures leading to formation of new compounds that would not appear under normal cure conditions and impacts VOC/SVOC calculation.;

—     case 2: where there are multi-pack coating materials other than case 3 and the expected VOC content is greater than a mass fraction of 1 %;

—     case 3: where there are radiation curable coating materials, and the expected VOC content is greater than a mass fraction of 5 %. Radiation curable coating materials in this document include coating materials that are cured by UV, electron beam, and other radiation methods.

If the system of the first case contains SVOC, but do not cure through chemical reactions, the VOC result can be influenced by SVOC, see Annex C. In this case, ISO 11890-2 is preferred. ISO 11890-1 cannot be used for the determination of the SVOC content. In water-borne coating materials, that do not cure through chemical reactions, if the water content is much greater than VOC content and VOC content is less than a mass fraction of 10 %, ISO 11890-2 is preferred.

For all three cases, the main purpose measured is VOC. However, clarify that this VOC content can also contain SVOC. The real VOC content can be lower than the VOC content measured by ISO 11890-1.

The method specified in this document assumes that the volatile matter is either water or organic. However, it is possible that other volatile inorganic compounds are present which can require another suitable method for quantification, which is thus allowed for in the calculations. The method defined in this document is not applicable for determination of water content.
