Foreword
This document (CEN/TS 13130-15:2005) has been prepared by Technical Committee CEN/TC 194
“Utensils in contact with food”, the secretariat of which is held by BSI.
This part of EN 13130 has been prepared within the Standards, Measurement and Testing project,
MAT1-CT92-0006, “Development of Methods of Analysis for Monomers” and has been prepared by
Subcommittee (SC 1) of TC 194 "Utensils in contact with food" as one of a series of test methods for
plastics materials and articles in contact with foodstuffs.

At the time of preparation and publication of this part of EN 13130 the European Union legislation
relating to plastics materials and articles intended to come into contact with foodstuffs is incomplete.

of this standard refer to the latest relevant published Directive(s) before commencement of a test or
tests described in this standard.
This part of EN 13130 should be read in conjunction with EN 13130-1.

Introduction
1,3-butadiene, C H or CH =CH-CH=CH , PM/Ref. No 13630, is a monomer used in the manufacture
4 6 2 2
of certain plastics materials and articles intended to come into contact with foodstuffs. After
manufacture, residual butadiene monomer can remain in the polymer and may migrate into foodstuffs
coming into contact with that plastics article.
NOTE However, the following should be taken into account when carrying out a migration test: From
migration experiments carried out at 10 d for 40 °C it was recognized that a considerable non-reproducible loss of
up to 90 %, due to volatilization of 1,3-butadiene can be obtained when using aqueous food simulants.
The method has been pre-validated by a collaborative trial with three laboratories.

1 Scope
This document, part of EN 13130, specifies an analytical procedure for the determination of butadiene
monomer in the food simulants water, 3 % w/v aqueous acetic acid, 15 % v/v aqueous ethanol and
olive oil. The level of butadiene monomer determined is expressed as mg butadiene/kg of food. The
method is appropriate for the quantitative determination of butadiene at a range of 0,01 mg/kg to 0,1
mg/kg in food simulants.
NOTE The method should also be applicable to other aqueous food simulants and to the other fatty food
simulants such as sunflower oil and a mixture of synthetic triglycerides.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
EN 13130-1:2004, Materials and articles in contact with foodstuffs – Plastics substances subject to
limitation – Part 1: Guide to test methods for the specific migration of substances from plastics to
foods and food simulants and the determination of substances in plastics and the selection of
conditions of exposure to food simulants.
3 Principle
The level of butadiene in a food or a food simulant is determined by headspace gas chromatography
(HSGC) with automated sample injection and using flame ionization detection (FID). Quantification is
achieved using an internal standard (n-pentane) with calibration against relevant food simulants
samples fortified with known amounts of butadiene. Confirmation of butadiene levels is carried out by
combined gas chromatography/mass spectrometry (GC/MS).

4.3 Solutions
4.3.1 Stock solutions of butadiene in DMAA with defined concentrations of approximately
5mg/g
Weigh a 50 ml sample vial (5.4), including septum and cap, to an accuracy of 1,0 mg. Pipette 50 ml
DMAA (4.2.1) into the vial (5.4), close and weigh again to 1,0 mg. Insert hollow needles equipped with
miniature two-way valves for introducing butadiene and for venting air and weigh again to an accuracy
of 1,0 mg. Introduce, under a fume hood, approximately 0,25 g butadiene (4.1.1) by bubbling through
the DMAA with the valves in the open position. Re-weigh the vial plus needles to an accuracy of
1,0 mg with the valves in the closed position and then remove the needles.
NOTE 1 For safety reasons, the use of hollow needles with miniature two-way valves is recommended but not
necessary. Alternatively, two separate needles can be used.
Calculate the concentration of butadiene in milligrams per gram of solution.
Repeat the procedure to provide a second stock solution.
NOTE 2 The stock solutions can be stored at – 20 °C up to 3 months protected from light in septum-capped
glass vials with minimum headspace; storage at + 4 °C with the exclusion of light should not exceed one week.
4.3.2 Diluted stock solutions of butadiene in DMAA with a defined concentration of
approximately 50 µg butadiene per gram DMAA
Weigh a 20 ml sample vial (5.4), including septum and cap, to an accuracy of 1,0 mg. Pipette 18,0 ml
of DMAA into the sample vial (5.4) and close the vial with the septum and cap. Weigh again to an
accuracy of 1,0 mg. Insert 2,0 ml of the stock solution (4.3.1) through the septum using a syringe (5.5),
mix thoroughly and re-weigh to an accuracy of 1,0 mg. Repeat this procedure taking the 1:10 diluted
stock solution instead of the stock solution (4.3.1) to obtain then the required 50 µg per gram diluted
stock solution.
Calculate the concentration of butadiene in the diluted stock solution in micrograms per gram of
solution.
Repeat the procedure to provide a second diluted stock solution.

1,0 mg. Pipette 19,6 ml, 19,2 ml, 18,4 ml, 17,6 ml and 16,0 ml DMAA into the vials, close and weigh
again to 1,0 mg. Add 0,4 ml, 0,8 ml, 1,6 ml, 2,4 ml and 4 ml of the diluted stock solution (4.3.2)
through the septum using a syringe, mix thoroughly and re-weigh to an accuracy of 1,0 mg.
Calculate the concentrations of butadiene in the standard solutions in micrograms per millilitre of
solution and in micrograms per 20 µl solution, using the density according to 4.2.1.
Repeat the procedure using the second diluted stock solution prepared in 4.3.2 to provide a second
set of standard solutions.
NOTE The standard solutions can be stored at – 20 °C for up to 3 months protected from light in septum
capped glass vials with minimum headspace; storage at + 4 °C with the exclusion of light should not exceed one
week.
