BSEN 14350:2020 EN 14350:2020 (E)
European foreword This document (EN 14350:2020] has been prepared by Technical Committee CEN/TC 252 '"Child care articles", the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2020, and conflicting national standards shall be withdrawn at the latest by June 2021. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 14350-1:2004 and EN 14350-2:2004.
The main changes compared to the previous edition are listed below:
— The standard has been completely renewed and a new structure was given. The former two parts were joined together into one standard. A whole series of new aspects had to be considered, following changes in the market and the regulatory background. — Introduction: Completely reworded and references to European regulations were renewed.
— Clause 3: Completely restructured and partly described in more detail. Definitions for completely new parts were added. — Clause 4: Several completely new parts were added. — Clause 5: This clause is completely new. — Clause 6: This clause is completely new.
— Clause 7: The whole clause has been divided into several sub-paragraphs for individual components of drinking equipment and the associated tests to improve the clarity of the sequence. Several paragraphs for new items and their tests were added. — Clause 8: This clause was completely restructured and subdivided. The requirements and test conditions have been set with the consideration of the likely chemical exposure: food contact, mouthing or ingestion. Chemical requirements and test methods were set for materials (like rubber, silicon, TPE, metal, glass) and exposures (mouthing and swallowing] which are recently not covered by harmonised legislations. Requirements for substances (e.g. Phthalates and BPA] covered by harmonised regulation (like REACH, (EU] 10/2011 or its amendments] have not been included.
— Clause 10: Revised and partly reworded. — Clause 11: This clause on Test report is completely new.
— Annex A: This normative annex with translations of warnings into 24 languages is completely new. — Annex B: This informative annex with rationales is completely new.

BSEN 14350:2020 EN 14350:2020 (E)
Introduction This document harmonises minimum safety requirements and test methods for children's drinking equipment. Some of the provisions have been taken from other existing national and European Standards and for these provisions the Technical Committee has relied on previous validation.
A significant choking hazard can arise if the component parts of drinking equipment become separated during use. This hazard is addressed in this document by the inclusion of a security test. However, as the fixing of such products to the container is user-dependent, the risk of an accident cannot be completely eliminated. This document sets out labelling requirements stating that parents or carers should not leave children unattended whilst being fed with a product containing a feeding teat or using a container made of glass and that children should not be allowed to use feeding teats as a soother. The Technical Committee considered the possibility of standardizing both sizes of feeding teats and ranges of flow rates. However, it was decided that the many combinations of container systems precluded being standardized. It is recommended that all container and drinking accessory combinations are matched components. Providing meaningful flow rate information is difficult because of several factors including hole diameter, teat thickness, hole shape/type of feed, and also how individual infants suck the teat. Accordingly, it was decided not to include a test for flow rate but to recommend that manufacturers provide information on flow rate and hole size that is appropriate to their particular product. This document sets chemical requirements and test methods for materials (like rubber, silicon, TPE etc) and exposures (mouthing and swallowing) not covered by harmonised legislations. Where this document sets migration limits for substances also covered by legislation, the requirements of this document with stated test conditions must be regarded as additional.
Materials and chemical risks included in the standard (Table 3) do not present a definitive list but the considered opinion of the Technical Committee based on current knowledge of likely risks.
All food contact materials and articles are regulated by Regulation (EC) No 1935/2004 [1], Regulation (EC) No 2023/2006 [39] and relevant implementation measures, at European or national level. All plastics components of drinking equipment intended to come into contact with food are specifically regulated by the Regulation (EU) 10/2011 [2] on plastic materials and articles intended to come into contact with food and its amendments. Therefore, for example the Bisphenol A - requirement has not been included in this document. [40]
Phthalates in childcare articles are restricted by Annex XVII of the REACH Regulation [3] and have not been included in this document.
Latex protein allergy risk has not been included in this document. There is no published information that sensitization is caused by feeding teats and there is an extremely low incidence of latex protein allergy among young children and babies. Nevertheless, provision for packaging information for feeding teats made from natural rubber latex has been included in this document.
It is recommended that manufacturers and suppliers operate to EN ISO 9001 standard for quality management systems [4]. It is also recommended that laboratories operate to EN ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories [5].

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) before 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 artificially 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 B in ISO 188:2011) at a temperature of (70 ± 2) °C.
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) min 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 carried out. The tests may be carried out in a non-conditioned room.
7
Construction and mechanical requirements 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. NOTE
If secure holding of the component causes problems, advice of the manufacturer should be considered.

BS EN 14350:2020 EN 14350:2020 (E)
7.11.1.2 Test procedure
Assemble the product with each possible configuration which can be used to feed the child. When the protruding part is a straw that can move up and down, perform the test when the base of the straw touches the internal base of the container.
Measure the length of the protruding part along the major axis using a suitable measuring device with an accuracy of 0,1 mm. The measurement is taken from the surrounding, flat surface of the protruding part, e.g. screw ring of a teat, up to the top end of the protruding part. 7.11.2 Flexibility 7.11.2.1 Principle
A force is applied to the end of the protruding part using a steel plate and the point at which the protruding part bends is measured. Assemble the product with each possible configuration which can be used to feed the child. When the protruding part is a straw that can move up and down, perform the test when the base of the straw touches the internal base of the container. 7.11.2.2 Requirement
When tested in accordance with 7.11.2.3 the protruding part shall collapse to less than 40mm. 7.11.2.3 Test procedure
Assemble the protruding part with its matched components) including the container. Clamp the container in a suitable device.

7.11.3 Security/retention test of protruding parts
7.11.3.1 Principle
The purpose is to test the security of a drinking accessory, when assembled as intended to be used which is why the test has to be done only on feeding teats. Non - elastic drinking accessories will normally not break or separate even at higher forces than required under 7.11.3.3. When tested in accordance with 7.11.3.3, any individual part of the product (excluding a straw) that constitutes a protrusion and that passes through templates A or B (see Figure 15) or protrudes from the base of the templates shall meet the requirements of 7.11.3.2. 7.11.3.2 Requirement
When tested in accordance with 7.11.3.3 no part of a feeding teat shall break, tear or separate from the container. 7.11.3.3 Test procedure
Orientate the component to be tested in a position which would most likely permit the entry of the component through the slot in the test template. Check if it passes through the slot or whether any part protrudes beyond the base of the template, using only the mass of the component. Assemble the component(s) to the container. Where a locking ring is provided, tighten it to a torque of (1,75 ± 0,25) Nm.
Secure the container at an angle of 45 degrees to the major axis (see Figure 13). Using a suitable clamping device, hold (10 ± 2) mm of the sides of the feeding teat in line with the major axis. Apply a pre-load of (5 ± 2) N at 45 degrees to the major axis of the feeding teat to ensure alignment, then increase the force to (60 ± 5) N in the same direction, at a crosshead speed of (200 ± 5) mm/min. Maintain for (10 ± 0,5) s.
7.12 Cords or loops 7.12.1 Principle
Cords and loops shall meet the requirements of 7.12.2 7.12.2 Requirement
When tested according to 7.12.3 the maximum length of a single cord shall not exceed 220 mm. If there is a loop it shall have a maximum circumference of 360 mm. If the loop opens when pulled with 90 N, the single cords shall each not exceed a length of 220 mm. Parts of the product which extend the circumference of the loop shall be included in the measurement of the loop. 7.12.3 Test procedure
A tensile force of (25 ± 2) N shall be applied in such a way that the longest length is achieved. After (60 ± 2) s measure the length whilst the force is still applied. All configurations shall be measured, in order to determine the longest length. A loop shall also be measured under a tension of (25 ± 2) N and the single length of one side is multiplied by two in order to calculate the circumference. Integrity of the loop shall be assessed by using a force of (90 ± 2) N. Use a suitable clamping device or other means fixing the clamped part of the loop securely. The points to apply the force are the two points where the loop ends and begins and the middle of the loop, which shall be determined by using the method to determine the longest length. Apply the force once in the most onerous way. If unclear, try several approaches. A preload of (5 ± 2) N shall be applied to align the specimen and the force shall 35

8.4.2.3 Calculation of results The volatile compounds content is calculated as follows:
Volatiles content [%] = j
[B -C}^(B - A]
j x 100
Where
A
is the weight of the watch glass after the drying step (g);
B
is the weight of the watch glass and the sample after the drying step (g);
C
is the weight of the watch glass and the sample after the heating step to 200 °C (g).
The difference between the lowest and highest determination shall be less than 0,1 %, otherwise the test shall be repeated.
The average of the multiple determinations shall be taken as the result. Any volatile compounds content result above the limit specified in 8.4.1 shall be subjected to an analytical tolerance of 0,3 %. Examples of applying the analytical tolerance are shown in Table 4.

The analytical tolerance is required to take into account the inherent variability in measurement shown by interlaboratory trials (see B.14).
The test report (see 11) shall show both the analytical and the calculated analytical results.
8.5 /V-nitrosamines and /V-nitrosatable substances release Feeding teats made of rubber and other elastomers are regulated by Commission Directive 93/11/EEC [10] and shall be tested according to EN 12868. Drinking accessories made of rubber and other elastomers shall be tested according to EN 12868 using the sample preparation procedures for elastomer and rubber teats given in that standard.
8.6 Migration of certain elements (see B.16 and B.21) 8.6.1 Requirement When tested in accordance with 8.6.2 the migration of elements from all materials shall not exceed any of the limits given in Table 5. Components manufactured from the same material may be tested as a composite sample or as individual colours. However, if any composite result is greater than any of the limits set in Table 5 divided by the number of components then any of the different colours shall be retested individually.
Decorations shall be scraped off the part of the material on which they are printed. If scraping off is not possible or the scraped off weight from one sample is less than 10 mg, the test for decorations as specified in EN 71-3 can be omitted. 41
