Introduction
The European Standard EN 71 for safety of toys consists of the following parts:
Part 1: Mechanical and physical properties
Part 2: Flammability
Part 3: Migration of certain elements
Part 4: Experimental sets for chemistry and related activities
Part 5: Chemical toys (sets) other than experimental sets
Part 6: Graphical symbols for age warning labelling
Part 7: Finger paints – Requirements and test methods
Part 8: Swings, slides and similar activity toys for indoor and outdoor family domestic use
Part 9: Organic chemical compounds – Requirements
Part 10: Organic chemical compounds – Sample preparation and extraction
Part 11: Organic chemical compounds – Methods of analysis
The standards EN 71-9, EN 71-10 and EN 71-11 were mandated by the European Commission (M/229) to
address the risks presented by organic compounds in toys by taking into account the potential exposure and
toxicological effects of those substances considered to present the greatest risk to health.
This European Standard specifies the procedures for preparing and extracting samples of toy materials prior
to analysis by the methods described in EN 71-11.
This part should be read in conjunction with EN 71-9, which contains requirements for certain organic
compounds in toys, and EN 71-11, which specifies methods of analysis.
This European Standard takes into account the opinion of the Toxicology Section of the Scientific Advisory
Committee published in 1992 (EUR 13976), which recommended that certain groups of chemical compounds
used in toys and toy materials need to be given special attention. In drafting this European Standard CEN/TC
52 has considered organic chemicals that can be classified within the following groups:
Solvents
Preservatives
1
Plasticisers (excluding phthalate plasticisers)
Flame retardants
Monomers
Biocides (wood preservatives)
Processing aids
Colouring agents
During the development of this European Standard, CEN/TC 52 has considered the requirements set out in
Council Directive 82/711/EEC as amended and its supporting standards.
1
Phthalate plasticisers were specifically excluded from the scope of mandate M/229.

6.1 Simulant (see B.7)
Water, deionized, demonstrably free of appropriate analytes.
6.2 Apparatus
6.2.1 Stainless steel tweezers
6.2.2 Extraction bottles, approximate volume 250 ml with flat base, a screw neck and provided with a
PTFE-lined rubber septum.
2
NOTE Bottles with the following dimensions have been found to be satisfactory
Outside diameter: 70 mm
Total height of bottle: 138 mm
Height from bottom to start of neck: 75 mm
Inside neck opening: 30 mm
The laboratory shall demonstrate that the containers and closures used do not contribute to or adsorb the
substances in question. Glassware and seals on vials and bottles shall be clean, undamaged and free from
defects.
3
6.2.3 Bottle rotator , capable of holding and rotating the extraction bottles in an end-over-end motion at a
constant speed. The distance from the centre of the rotating axis to the centre of the flask shall be
approximately 150 mm.
6.3 Sampling
2
If the approximate surface area of the laboratory sample is less than 10 cm , test the sample uncut.
In other cases, select the most appropriate part of the laboratory sample, from which to obtain a test portion of
2
(10 ± 1) cm , in such a way as to minimize the inaccessible and internal surfaces. Where possible, choose a
test portion from a thin part of the laboratory sample. Remove a disc, or other shaped piece if this reduces the
2
amount of cut edges, with a surface area of (10 ± 1) cm using a suitable cutting instrument. Measure the
approximate surface area of the test portion taking into account the thickness when this is greater than 1 mm.
The edges of the test portion should be smooth in appearance.
In cases where the preparation of the laboratory sample leads to unrealistic results because of the cutting
process, the whole uncut toy or toy component may be tested using proportionate extraction volumes and
2
apparatus. However, sample sizes of less than 10 cm shall be extracted using 100 ml of simulant (see B.7).

Examine the laboratory sample and determine which textile components are present and accessible, and
2
have an accessible area of 10 cm or more.
2
Remove test portions from the textile components having an accessible area greater than 10 cm on the toy.
The test portions may be cut from the laboratory sample with a suitable blade. Cut each test portion such that
no dimension exceeds 3 mm. Store each test portion separately in a suitable container.
Weigh, to the nearest 1 mg, approximately 0,5 g of the test portion into a 20-ml amber glass vial with a PTFE-
liner screw cap. Add 5 ml acetonitrile and place the vial in an ultrasonic bath for 60 min at 40 °C. Filter the
extract, transfer to a vial and crimp.
Analyse the extract in accordance with 5.2 of EN 71-11:2005.
8.1.2 First-action method for colourants and primary aromatic amines
This test, specified in Annex A and based on EN ISO 105-E04, is an assessment of whether any colourants
can be transferred from textile toy materials to the mouth, mucous membranes or skin. If textiles are found
not to be colourfast when tested in accordance with the test procedure described in Annex A, they shall be
tested by the final-action method for colourants (8.1.3) and the final-action method for primary aromatic
amines (8.1.4).

8.1.3 Final-action method for colourants
Examine the laboratory sample and determine which textile components are present and accessible, and
2
have an accessible area of 10 cm or more. Different colours of the same textile material shall be treated
separately.
2
Remove test portions from the textile components having an accessible area greater than 10 cm on the toy.
Components which have stained the multifibre fabric in the first-action method for textiles (8.1.2) shall be
2
tested if their area is greater than 1 cm .
The test portions may be cut from the laboratory sample with a suitable blade. Cut each test portion such that
no dimension exceeds 3 mm. Store each test portion separately in a suitable container.
Weigh, to the nearest 1 mg, approximately 0,5 g of the test portion into a 40-ml amber glass vial with a PTFE-
liner screw cap. Add 10 ml ethanol and place the vial in an ultrasonic bath for 15 min. Transfer the extract
into a test tube and concentrate to about 1 ml under a stream of air or nitrogen. Filter the extract, transfer to a
2-ml vial and crimp.
Analyse the extract in accordance with 5.3 of EN 71-11:2005.
8.1.4 Final-action method for primary aromatic amines
Obtain test portions of the laboratory sample in the same way as detailed in 8.1.3.
Weigh, to the nearest 1 mg, approximately 1,0 g of the test portion into a 50-ml polypropylene tube. Add
15 ml water (6.1) and agitate on a Vortex mixer for 30 s.
4
and
Centrifuge the tube at 2 000 g for 15 min. Pour the supernatant liquid onto a porous kieselguhr column
allow it to absorb for 20 min.
Extract the kieselguhr with 2 x 40 ml tert-butyl methyl ether. Combine the eluates in a 100-ml round-bottomed
flask and evaporate at 50 °C to approximately 5 ml using a rotary evaporator.
Transfer the ether extract to a graduated 10-ml test tube and then carefully reduce to 1 ml under a gentle
stream of nitrogen at ambient temperature. Transfer the concentrated extract to a 2-ml vial and crimp.
NOTE 1 It should be avoided evaporating the ether extract to dryness as this has been shown to adversely affect
amine recovery.
NOTE 2 The recovery of amines can be improved by converting them to their hydrochloride salts.
