Scope: This standard specifies the qualitative and quantitative methods for the determination of short-chain chlorinated paraffins in electrical and electronic products by gas chromatography-electron capture negative chemical ion source mass spectrometer. This standard applies to the determination of short-chain chlorinated paraffins in electrical and electronic products, with a limit of quantification of 100 mg/kg, of which gas chromatography-electron capture negative chemical ion source mass spectrometry is applicable to those with chlorine atoms greater than or equal to 5 in electrical and electronic products Determination of short-chain chlorinated paraffins. When determining short-chain chlorinated paraffins with less than 5 chlorine atoms in electrical and electronic products, refer to the methods in Appendix A or Appendix B.
