该方法的原理是用合适的溶剂稀释样品，通过离心分离色素。本文描述了三种方法，具体取决于所检查产品的粘合剂。以1:15的质量体积比用盐酸萃取分离的颜料，但测定“可溶性”铅除外；在这种情况下，提取以1:1000的比例进行。通过离心、干灰化分析和硝酸提取灰分获得的液体部分蒸发至干燥。对于粉末形式的涂层材料，在不分离粘合剂的情况下进行萃取。

The principle of the method consists in the dilution of a sample with a suitable solvent, separation of the pigment by centrifugation. Three methods, dependent on the binder of the product being examined, are described. Extraction of the separated pigment with hydrochloric acid at a ratio of mass:volume of 1:15, except for the determination of "soluble" lead; in that case, extraction is carried out at a ratio of 1:1000. Evaporation to dryness of the liquid portion obtained by centrifuging, analysis by dry ashing and extraction of the ash with nitric acid. For coating materials in powder form, extraction is carried out without prior separation of the binder.
