6 Construction and mechanical properties — General and sample preparation
6.1 Sample preparation for construction and mechanical properties
Samples of single-use products shall be conditioned (6.5) before testing.
Samples of re-usable products shall be boiled (6.4) and conditioned (6.5) before testing.
Samples of any products containing vulcanized rubber shall be pre-treated (6.3) berore being submitted to the above sample preparation.
6.2 General
All samples shall be at least 3 days post-production (see B.3).
6.3 Pre-treatment (see B.4)
Parts made of vulcanised rubber (not silicone parts) taken directly from the manufacturer prior to being shipped to a retailer, shall be artlflcially aged for (7 days) ± 2 h in an oven with forced air circulation by means of a fan and a ventilation of three to ten changes per hour (as described as Method Bin ISO 188:2011) at a temperature of(70 t 2) DC.
6.4 Boiling (see B.5)
All samples, excluding single-use products, shall be disassembled and immersed in boiling water, to the requirements of EN ISO 3696, Grade 3, for (10 ± 1) mm without touching the walls of the container and removed. Afterwards allow the samples to cool to room temperature. Then after a maximum of 2 h after boiling place in the conditioning room (see 6.5).
After boiling, there shall be no damage which causes the failure of any subsequent tests, or impairs the assembly for the intended use and no graduation shall have been removed when assessed by visual inspection.
6.5 Conditioning
All samples shall be conditioned for at least 40 h before the tests, at a temperature (23 ± 2) °C and relative humidity (50 ± 5) %. Samples shall remain in the conditioning atmosphere until the test is earned out. The tests may be carried out in a non-conditioned room.
7 Construction and mechanical requirement.s and tests
7.1 Order of testing for construction and mechanical properties
The tests for construction and mechanical properties shall be carried out in the order given in Table 1, after treatments according to Clause 6.
New samples, preferably from the same batch, shall be used for each test (i.e. samples used in one test shall not be used in another test) unless otherwise stated.
When tensile tests are applied, clamps or other devices shall hold the components securely during the test without causing damage which results in a test failure. Any failure due to such damage shall be disregarded. If after a number of attempts using different methods secure holding is not possible due to material weakness, the product fails.
7.2 Decoration, inscription and decals (see B.6)
All areas of drinking equipment may be decorated or inscribed by techniques which do not apply materials to their surface. e.g. by laser engraving. The manufacturer has to make sure that possible contamination. e.g. from laser engraving combustion products, does not impair product safety.
Areas with intended food contact may only be printed or inmold labelled, if this printed or inmold labelled area Is completely covered by a functional barrier according to EU/1O/201 1 (2J.
Areas of drinking accessories (3.2) that are intended or foreseeable to be mouthed shall not be printed. also not when covered by a functional barrier including inmold labelling.
A drinking cup (3.3.2) whIch provides a drinking rim and Is also intended to be used without a drinking accessory (3.2) or a similar product where the child’s mouth can contact the outside of the cup shall not be printed and / or inmold labelled on the area extending to 20 mm measured from the drinking rim.
Areas of drinking equipment that are not intended to contact food and/or to be mouthed may be decorated or inscribed with techniques which apply colorant such as printing with printing inks.
Adhesive decals and labels intended to stay on the product during use are not allowed on any part of drinking equipment. Decorations shall not be attached to any part of drinking equipment by glue.
7.3 Visual and tactile examination
All components of drinking equipment when assembled for use shall be free from any accessible sharp points or edges and free of flash and burrs, which could cause injuries, and shall be assessed by visual and tactile examination. In case of doubt apply test for sharp point and sharp edge according to
EN 71-1.
7.4 Small parts
All parts which are designed to be removed (e.g. for cleaning), or become separated after the tensile or other mechanical tests shall not fit entirely within the small parts cylinder (see Figure 11) in any orientation and without compression.
7.5 Additional requirements for sealing discs (see B.7)
The minimum diameter of a sealing disc shall be 35 mm.
7.6 ReqLlirements and tests for containers
7.6.1 Volumetric labelling requirements (see 11.0)
If containers are marked with graduations these shall include the nominated maximum capacity. The volumes shall be given in millilitres and the letters ml or “mL shall appear at least once. Additional units for measurement can be used if applicable.
Drinking cups. feeding bags or holders for feeding bags may be marked with graduations. Feeding bags with graduations shall not be used to prepare formula milk (see 10.3.3).
All feeding bottles shall be marked with graduations. The lowest numbered graduation shall not be more than 60 ml and the highest graduation, numbered or unnumbered, shall be the nominal capacity of the bottle. There shall be numbered or unnumbered graduations every 3Oml starting from 60 ml. The gap between numbered graduations shall not exceed 60 ml.
7.6.2 VolumetrIc accuracy
7.6.2.1 Volumetric accuracy requirements (see B.8)
When tested in accordance with 7.622 the volumetric accuracy of all graduations, unnumbered and numbered, on feeding bottles or if present on feeding cups shall be as follows:
— all graduations  100 ml: ± S %;
— all graduations c 100 ml: ± 5 ml.
For feeding bags and holders for feeding bags that have graduations their volumetric accuracy shall be within ±15% as measured according to 7.6.2.2 with the product set up by the method given in the instructions for use.
7.6.2.2 Volumetric accuracy test procedure
Fill the container with distilled or prebolled water at (20 ± 5) C to each of the numbered and unnumbered graduations (where present).
Check the mass of the water using a balance, with an accuracy of ± 0.1 g.
Ensure that the base of the meniscus of the water is level with the middle of the graduation.
7.6.3 PrInt adhesion of graduations (see B.10)
7.6.3.1 Requirement
All containers with printed graduations intended for repeated use shall be tested. After being tested in accordance to 7.6.3.3 all graduations required under 7.6.1, numbered and unnumbered, shall be readable (see Figure 17).
7.6.3.2 Equipment
7.6.3.2.1 Adhesive tape
Adhesive tape with an adhesion strength of (10 ± 1) N per 25mm width when tested in accordance with
IEC 60454-2.
7.6.3.2.2 Eraser
A non-abrasive eraser shall be used.
7.6.3.3 Test procedure
Carry out the test on the whole area of the container where the graduations are printed. Containers which do not have numbered graduations shall not be tested.
Place the adhesive tape (7.6.3.2.1) over the printed graduations and smooth by hand in every direction.
To ensure a good contact rub the surface of the adhesive tape with the eraser (7.6.3.2.2), except for a
(10 ± 2) mm length at one end of the tape. Leave for (5 ± 1) miii. Then remove the tape by grasping the
free end and pulling it off steadily in 0.5 s to 1.0 s, depending on the length of the tape at an angle of
(60 ± 10) as shown in Figure 16.BS EN 14350 pdf free download.BS EN 14350:2020 Child care articles一Drinking equipment一 Safety requirements and test methods
