China China begins public consultation for RoHS-related industry standard

“Measurement of seven phthalates used in electrical and electronic devices: High-performance liquid chromatography”

China begins public consultation for RoHS-related industry standard

On March 3, 2022, the China Electronics Standardization Institute announced a solicitation for opinions regarding the RoHS-related industry standard “Measurement of seven phthalates used in electrical and electronic devices: High-performance liquid chromatography” and began soliciting opinions. The deadline for opinions is April 8. The standard was developed to promote the spread of high-performance liquid chromatography (HPLC), which causes less pollution, is easier to operate, and is less costly than the traditional measurement method GC-MS. The standard specifies the method for measuring the content of seven phthalates (DIBP, DBP, BBP, DEHP, DNOP, DINP, DIDP) used in electrical and electronic devices using high-performance liquid chromatography, and applies to 11 items of the EU RoHS 2 Directive [2011/65/EU].

Scope of Application

The standard specifies the method for measuring the content of seven phthalates (DIBP, DBP, BBP, DEHP, DNOP, DINP, DIDP) used in electrical and electronic devices using high-performance liquid chromatography and applies to the measurement of the content of seven phthalates used in electrical and electronic devices subject to RoHS regulation (11 items of the EU RoHS 2 Directive [2011/65/EU]). Testing based on the standard must be performed by trained test personnel.

The seven phthalates are as shown in the table below.

Number

Name Abbreviation

CAS Number

1 Diisobutyl phthalate DIBP 84-69-5
2 Dibutyl phthalate DBP 84-74-2
3 Butyl benzyl phthalate BBP 85-68-7
4 Di (2-ethylhexyl) phthalate DEHP 117-81-7
5 Di-n-octyl phthalate DNOP 117-84-0
6 Di-iso-nonyl phthalate DINP 68515-48-0
7 Di-iso-decyl phthalate DIDP 26761-40-0

Quantitation Limit (QL)

The quantitation limits of the seven phthalates are as follows.

  • Solid samples: DIBP, DBP, BBP, DEHP, and DNOP at 10 mg/kg and DINP and DIDP at 50 mg/kg.
  • Fluid samples: BBP, DIBP, DBP, DEHP, DNOP at 10 mg/kg and DINP and DIDP at 50 mg/kg.
