ActiveDetermination of restricted substances including tributyltin and triphenyltin in electrical and electronic products—Gas chronatography-mass spectrometry
电子电气产品中的限用物质三丁基锡和三苯基锡的测定 气相色谱-质谱法
Application Summary AI generated
This standard specifies a gas chromatography-mass spectrometry (GC-MS) method for determining the presence of tributyltin (TBT) and triphenyltin (TPT) in electrical and electronic products. It is applied by manufacturers and testing laboratories to verify compliance with substance restrictions, such as those in the EU RoHS directive, for components like plastics, coatings, and circuit boards. The method ensures accurate quantification of these organotin compounds, which are used as stabilizers or biocides, to support regulatory conformity and product safety assessments.
