Determination of coating phthalate content
Gas Chromatography/Mass Spectrometry
1 Scope
This standard specifies the determination by gas chromatography/mass spectrometry coatings phthalate content.
This standard applies to the determination of paints and coatings raw materials in a variety of phthalate content. Including but not limited to, include phthalic
Carboxylic acid esters, such as dibutyl phthalate (DBP), phthalate, butyl benzyl phthalate (BBP), di-iso-octyl phthalate (DEHP), phthaloyl
Acid dioctyl ester (DNOP), diisononyl phthalate (DINP), diisodecyl phthalate (DIDP), etc. Other types of phthalic
Dicarboxylate can also be performed with reference to the present method.
