EN 71-10-2005 pdf download.Safety of toys – Part 10 : Organic chemical compounds – Sample preparation and extraction.
Test portions shall be representative of the toy matenal in the laboratoiy sample. Test portions shall only be taken from accessible parts of the toy.
6 Migration — Sampling and extraction
6.1 Simulant (see B.7)
Watec. 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
NOTE Bottles with the following dimensions have been found to be satisfactory2
Outside diameter: 70 mm
Total height of bottle: 138mm
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.
6.2.3 Bottle rotator3, 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
If the approximate surface area of the laboratory sample is less than 10 cm2, test the sample uncut.
In other cases, select the most appropriate part of the laboratory sample, from which to obtain a test portion of (10 ± 1) cm’, in such a way as to minimize the inaccessible and internal surfaces. Where possible, choose a test port on from a thin part of the laboratory sample. Remove a disc, or other shaped piece if this reduces the amount of cut edges, with a surface area of (10 ± 1) cm2 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 apparatus. However, sample sizes of less than 10 cm2 shall be extracted using 100 ml of simulant (see B.7).
Place the test portion into the extraction bottle using tweezers. Add 100 ml simulant (61) at (20 ± 2) C.
Close the extraction bottle and secure it in the rotator. Rotate the bottle at (60 ± 5) rlmin for (60 ± 5) mm.
Filter the aqueous migrate in the bottle through a plug of glass wool.
Analyse the aqueous migrate using the appropriate method(s) specified in EN 71-11.
7 Inhalation — Sampling, extraction and analysis
7.1 First-action method for solvents
See A.2 of EN 71-11:2005
7.2 Final-action method for solvents See A.3 of EN 71-11:2005
8 Specific sampling and extraction procedures
8.1 Textiles — Flame retardants, colourants and primary aromatic amines
8.1.1 Flame retardants
Examine the laboratory sample and determine which textile components are present and accessible, and have an accessible area of 10 cm2 or more.
Remove test portions from the textile components having an accessible area greater than 10 cm2 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-mI amber glass vial with a PTFEliner screw cap. Add 5 ml acetonitrile and place the vial in an ultrasonic bath for 60 mm 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 metl7od for colourants (8.1.3) and the final-action method for primary aromatic amines (8.1.4).EN 71-10-2005 pdf download.
