BS EN 62321-8:2017 specifies two normative and two informative techniques for the
determination of di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzylbutyl
phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP), di-isononyl
phthalate (DINP) and di-iso-decyl phthalate (DIDP) in polymers of electrotechnical products.
Gas chromatography-mass spectrometry (GC-MS) and gas chromatography-mass
spectrometry (Py/TD-GC-MS) techniques are described in the normative part of this document.
The GC-MS method is considered the referee technique for the quantitative determination of
DIBP, DBP, BBP, DEHP, DNOP, DINP and DIDP in the range of 50 mg/kg to 2 000 mg/kg.
The GC-MS coupled with a pyrolyzer/thermal desorption (TD) accessory is suitable for
screening and semi-quantitative analysis of DIBP, DBP, BBP, DEHP, DNOP, DINP, and DIDP
in polymers that are used as parts of the electrotechnical products in the range of 100 mg/kg
to 2 000 mg/kg.
The IAMS technique is suitable for screening and semi-quantitative analysis of DIBP, DBP,
BBP, DEHP, DNOP, DINP, and DIDP. Determination of DBP and DIBP, DEHP and DNOP by
IAMS has not been established due to peak and mass spectral resolution limitations.
The LC-MS technique is limited to the determination of of BBP, DEHP, DNOP, DINP, and
DIDP. Determination of DBP and DIBP by LC-MS has not been established due to peak and
mass spectral resolution limitations.
A flow chart depicting how the normative Py/TD-GC-MS and GC-MS methods and informative
methods using ion attachment mass spectrometry (IAMS) coupled with direct injection probe
(DIP) and liquid chromatography-mass spectrometry (LC-MS) can be used are provided in
annexes of this document.
These four test methods have been evaluated by the test of PE (polyethylene) and PVC
(polyvinyl chloride) materials containing individual phthalates between ~450 mg/kg to
30 000 mg/kg as depicted in the normative and informative parts of this document. The use of
the four methods described in this document for other polymer types, phthalate compounds or
concentration ranges other than those specified above has not been specifically evaluated.
