27、 3 years or a maximum weight of 15 kg. The European Standard does not apply to products only aimed at restraining the child on a chair without raising the childs sitting position. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are
28、 indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The tests are designed
38、to be applied to chair mounted seats that are fully assembled and ready for use in accordance with the manufacturers instructions. If the chair mounted seat can be assembled or adjusted in different ways, the most onerous combination shall be used for each test. 5.3 Application of forces The forces
39、in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic force is applied. 5.4 Tolerances Unless otherwise stated, the following tolerances apply: Forces: 5 % of the nominal force; Masses: 0,5 % of the nominal mass; Dimensions: 1,0 mm of the nominal dimension;
40、Angles: 2 of the nominal angle; Positioning of loading pads: 5 mm; Duration of forces: 1 s. The tests are described in terms of the application of forces. Masses can however be used: 1 kg mass may be used for 10 N force. Unless otherwise specified, the test forces may be applied by any suitable devi
41、ce which does not adversely affect the results. 5.5 Order of test Unless otherwise stated, the requirements of Clause 8 shall be assessed on the same chair mounted seat in the order listed in this standard. 6 Chemical hazards - Migration of certain elements (see A.2) The migration of elements from c

Where a surface is coated with a
44、multi-layer of paint or similar coating, the test sample shall not include the base material. A separate sample may be used for these tests. 7 Thermal hazards (see A.3) When tested in accordance with EN 1103 there shall be no flash effect. These requirements apply to parts with an area greater than
45、310 cm. A separate sample may be used for these tests. 8 Mechanical hazards (see A.4) 8.1 Hazards due to height adjustment or folding of the product 8.1.1 General Chair mounted seats in which the height of the sitting area can be adjusted shall have locking mechanism(s), complying with 8.1.2, to mai
46、ntain the chair mounted seat in its position of normal use. Chair mounted seats in which the base can be folded for storage shall have locking mechanism(s), complying with 8.1.2, to maintain the chair mounted seat in its position of normal use. Chair attachment systems shall not be considered as loc
47、king mechanisms for height adjustment of the sitting area. Inflatable systems shall be fitted with non-return valves. 8.1.2 Unintentional release of locking mechanism(s) To avoid the hazards due to unintentional release of locking mechanisms, one of the following conditions shall be fulfilled before
48、 and after testing in accordance with 8.1.3: a) at least one locking mechanism requires an operating force greater than 50 N, or b) at least one locking mechanism is released by the use of a tool, or c) height adjustment requires at least two consecutive actions, the first of which shall be maintained while the second is carried out, or d) height adjustment requires at least
