line intersection of the seat and the back rest 4 General 4.1 Test conditions The high chair shall be tested as delivered. If the high chair is a knock-down type, it shall be assembled according to the instructions supplied with it. If the instructions allow for different adjustments or configurations of components (e.g. inclination of the backrest, height of the seat, position of the tray, position of castors/wheels, etc.), the most onerous combination shall be used for each test, unless otherwise specified in the test method. Knock-down fittings shall be tightened before testing. Further re-tightening shall not take place. 4.2 Application of forces The forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic force is applied. The tests are described in terms of the application of forces, however masses can be used. The relationship 10 N = 1 kg shall be used for this purpose. 4.3 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; — Angles: ± 2° of the nominal angle; — Positioning of loading pads: ± 5 mm.

The peripheral dimension of a loop shall be measured from the fixing point on the high chair of one end to the
fixing point of the other end under a 25 N tensile force. 8.6 Choking and ingestion hazards (see A.4.4) 8.6.1 Requirements Any component that is considered capable of being gripped by a child in accordance with 8.6.2.1 shall be tested in accordance with 8.6.2.2 and 8.6.2.3. Any component or part of a component that is removed shall not fit entirely within the small parts cylinder specified in 5.11. With the exception of the back of the backrest, parts from the floor up to and including the under-surface of the seat, and buckles and adjusters of the restraint system, parts of a high chair containing filling material shall have at least one covering. After testing in accordance with 8.6.2.4, it shall not be possible to insert the 12 mm probe by more than 10 mm (see 5.9) with a force of 30 N through any opening in the covering materials or their joints that gives access to the filling material.

Prevent movement of the high chair on the floor surface without impairing the test. Place the wood block (5.18) in the centre of the seat. Position the impactor (5.17) above the wood block and let it drop freely from a height of 75 mm. Repeat for a total of 500 cycles at a frequency of (15 ± 1) cycles per minute. SIST EN 14988:2017
