The work of preparing International Standards is normally carried ou

10、t through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO co

11、llaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different app

12、roval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the

13、 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

27、ISO 2015 All rights reserved ISO 9221-1:2015(E) 5 Construction 5.1 General The requirements apply to a high chair assembled and erected in accordance with the manufacturers instructions. If parts of the high chair are designed to be removable (e.g. a tray or a footrest), the requirements apply to th

28、e high chair with and without this part(s). Connecting screws for direct fastening, e.g. self tapping screws, shall not be used for the assembly of any component that is designed to be removed or loosened when dismantling the high chair for the purpose of transportation or storage. Exposed edges and

29、 protruding parts shall be rounded or chamfered and free from burrs and sharp edges. 5.2 Holes, gaps and openings With the exception of all parts of the high chair below the under-surface of the seat, the integral harness and the waist belt, there shall be no holes, gaps or openings between 7 mm and

30、 12 mm accessible when the child is seated, which are deeper than 10 mm, when tested in accordance with ISO 9221-2:, 6.6.2. With the exception of the entrance to the seat unit and the two openings for the childs legs to pass through, there shall be no holes, gaps or openings above the seat surface w

31、hich allow the small torso probe to pass through when tested according to ISO 9221-2:, 6.6.2. 5.3 Moving parts The requirements of this subclause do not apply to locking mechanisms. To avoid the risk of shearing and crushing, shear and compression points shall be avoided. If shear and compression po

32、ints cannot be eliminated for functional reasons, then the conditions for individual cases in 5.3.1, 5.3.2 and 5.3.3 shall be applied. 5.3.1 Shear and squeeze points when setting up and folding away Shear and squeeze points that are accessible only when the product is being set up or folded away are

33、 permitted if they are not under the influence of a powered mechanism. 5.3.2 Shear and squee ze points under the influen c e of po w er ed mechanism If shear and squeeze points are created by parts operated by spring force or other sources of energy, the distance between moving parts shall not be le

34、ss than 18 mm unless the distance is always less than 5 mm when tested according to ISO 9221-2:, 6.6.1. 5.3.3 Shear and squee ze points under the influen c e of bod y w eig ht or other e xt ernal for c es When tested in accordance with ISO 9221-2:, 6.6.1, any part of the product which can fold or be

35、 detached shall be locked to avoid release by the child using the product, by another child or by unintentional action by an adult. Unintentional movement is ruled out in any of the following: a) locking mechanism is automatically engaged and the load has a closing effect on the locking mechanism; b

36、) at least two independent locking mechanisms are provided for the movable part or system; c) locking mechanisms under load cannot be released unintentionally. ISO 2015 All rights reserved 3 ISO 9221-1:2015(E) When the product has been deployed for use, there shall be no accessible squeeze points wh

37、ich can be closed to less than 12 mm when tested according to ISO 9221-2:, 6.6.2. 5.4 Locking mechanisms for folding high chairs 5.4.1 General Locking mechanisms are required to prevent a high chair from folding whilst a child is in the high chair and also when a child is being put in and taken out

38、of the high chair. 5.4.2 Incomplete deployment To avoid the hazard due to incomplete deployment, either a) weight of the child using the product shall act to prevent the folding, or b) at least one locking mechanism shall engage automatically when the product is deployed for use. 5.4.3 Unintentional

39、 folding of the high chair Unintentional folding of the high chair shall be avoided. This requirement is fulfilled if a) at least one locking mechanism requires a minimum force of 50 N before and after test in accordance with ISO 9221-2:, 6.3, b) at least one locking mechanism requires the use of a

40、tool to be released, c) folding is only possible when two independent locking mechanisms are operated simultaneously, d) there are two or more automatically engaging locking devices that cannot be released by one single action, or e) folding of the high chair requires two consecutive actions, the fi

41、rst of which shall be maintained while the second is carried out. 5.4.4 Locking mechanism strength When tested in accordance with ISO 9221-2:, 6.4, the high chair shall not collapse. The locking mechanism shall remain engaged. 5.5 Small parts When tested in accordance with ISO 9221-2:, 6.5, no part

42、that can be detached shall fit wholly within the cylinder. Parts that clearly will not fit in this cylinder shall not be tested. Any component intended to be removable without the use of a tool shall not fit wholly within the cylinder. 5.6 Restraint system 5.6.1 General The high chair shall have an

43、active restraint system complying with 5.6.2 or a passive restraint system complying with 5.6.3. If the backrest can be reclined to less than 60 to the horizontal, measured in accordance with ISO 9221-2:, 6.10.1, the product shall have an active restraint system complying with 5.6.2.4 ISO 2015 All r

44、ights reserved ISO 9221-1:2015(E) All straps of the restraint system shall have a minimum width of 19 mm. When a high chair is fitted with attachment points for an additional harness as described in the instructions for use, these shall function as intended after testing in accordance with ISO 9221-

45、2:, 6.7. These attachment points shall be independently fixed and shall at all times remain within 50 mm in front of and not more than 75 mm above the junction line (see Figure 2). All parts of the restraint system shall function as intended before and after testing in accordance with ISO 9221-2:, 6

46、8. The maximum slippage of the straps through any type of adjuster shall be 20 mm, when tested in accordance with ISO 9221-2:, 6.9. After testing in accordance with ISO 9221-2:, 6.9, adjusters and buckles shall function as intended. 5.6.2 Requirements for high chairs with an active restraint system

47、 The active restraint system shall be supplied with the high chair. The high chair shall be fitted with lateral protection complying with 5.7.2 or 5.7.3. The restraint system shall comprise of at least one of the following: a) a waist belt adjustable to the size of the child and a crotch strap, wher

48、e the crotch strap shall be such that the waist belt can be used only in conjunction with it; b) an integral harness adjustable to the size of the child and comprising of either 1) a crotch restraint, a waist strap and shoulder straps, where the crotch restraint shall be such that the waist strap ca

49、n be used only in conjunction with it, or 2) straps that pass over the childs shoulders and between the childs legs. 5.6.3 Requirements for high chairs with a passive restraint system When the high chair is not supplied with an active restraint system, a passive restraint system shall be provided complying with the following requirements: a) the high chair shall be fitted with lateral protection complying with 5.7.3; b) the high chair shall comprise a crotch restraint and a horizontal element whic
