Part 1 Guide to the test methods for specific migration of substances from plastics into foods
and food simulants and the determination of substances in plastics and the selection
of conditions of exposure to food simulants
Part 2 Determination of terephthalic acid in food simulants (SML = 7.5 mg/kg)
Part 3 Determination of acrylonitrile in food and food simulants (SML = not detectable, DL
= 0.02 mg/kg)
Part 4 Determination of butadiene in plastics (QM = 1 mg/kg)
Part 5 Determination of vinylidene chloride in food simulants (SML = not detectable, DL =
0.05 mg/kg)
Part 6 Determination of vinylidene chloride in plastics (QM = 5 mg/kg)
Part 7 Determination of monoethylene glycol and diethylene glycol food simulants (SML(T)
= 30 mg/kg)
Part 8 Determination of isocyanates in plastics (QM = 1 mg/kg)
SML
= specific migration limit in food or food simulant
QM
= maximum permitted quantity of the 'residual' substance in the material or article
DL
= detection limit of the method of analysis
Precision data `r' and `R' for test methods in Parts 2 to 8 have been obtained by means of
collaborative trials.
Only the ENV standard was covered by the European Commission/EFTA mandate.
During 2000 a further 20 Work Items were added to the Working Group 2 Work Programme. These
consisted of 20 monomer test methods which had been produced in the BCR Project Development of
Methods of Analysis for Monomers and Other Starting Substances with SML and/or QM Limits in
Directive 90/128/EEC and 92/39/EEC
- Report No. EUR 17560 EN, Published 1997.
The number of monomer test methods published in the report was 35. The number was reduced to 20
for the new Work Items by removing the method for BADGE (now covered separately by Working
Group 8), eliminating those for which further development work was required and consolidating a
number of like methods. The 20 Work Items with corresponding prEN 13130 Part numbers are given
in the Table 3, below.
