1 Scope

This part of GB/T 39560 describes two standard methods and two reference methods for the determination of polymers in electronic and electrical products

Diisobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), butyl benzyl phthalate (BBP), two phthalate

Isooctyl ester (DEHP), di-n-octyl phthalate (DNOP), diisononyl phthalate (DINP) and diisodecyl phthalate

Esters (DIDP).

The standard methods in this section are gas chromatography-mass spectrometry (GC-MS) and gas chromatography-mass spectrometry (Py/T D-

GC-MS) method.

The GC-MS method is a standard method for quantitative determination of DIBP, DBP, BBP, DEHP, DNOP, DINP and DIDP. The measurement range is from

50mg/kg to.2000mg/kg.

Equipped with pyrolysis/thermal desorption gas chromatography-mass spectrometry (Py/T D-GC-MS), suitable for screening and semi-quantitative analysis of electrical and electronic products

DIBP, DBP, BBP, DEHP, DNOP, DINP and DIDP in polymer materials, the measurement range is from 100 mg/kg to

2000mg/kg.

Ion Adhesion Mass Spectrometry (IAMS) is suitable for screening and semi-determination of DIBP, DBP, BBP, DEHP, DNOP, DINP and DIDP

For quantitative analysis, see Appendix A for details. Due to the limitation of mass spectrum peak resolution, the method of determining DBP and DIBP, DEHP and DNOP by IAMS method

The law has not yet been determined.

Liquid chromatography-mass spectrometry (LC-MS) is limited to the determination of BBP, DEHP, DNOP, DINP and DIDP, see Appendix B for details. because

The limit of mass spectrum peak resolution, the method of determining DBP and DIBP by LC-MS technology has not yet been determined.

The flowchart provided in Appendix C describes how to use two standard methods. Py/T D-GC-MS and GC-MS, and how to use both

Two reference methods. Direct Injection (DIP)-Ion Adhesion Mass Spectrometry (IAMS) and Liquid Chromatography-Mass Spectrometry (LC-MS).

These four test methods have passed the testing of polyethylene (PE) and polyethylene (PE) with a phthalate content of about 450mg/kg to 30000mg/kg

Evaluation of polyvinyl chloride (PVC) materials. The four methods described in this section are effective for other polymer types, phthalic acid compounds, or

The use outside the stated concentration range has not been specifically evaluated.
