BS EN 14988:2017EN 14988:2017 (E) 5 1 Scope This European Standard specifies safety requirements for free standing childrens high chairs that elevate children to dining table height usually for the purposes of feeding or eating. Childre

30、ns high chairs are for children up to 3 years of age who are capable of sitting unaided. With the exception of special high chairs for medical purposes, this standard applies to childrens high chairs for domestic and non-domestic use. NOTE If a childrens high chair has to or can be converted into ot

31、her functions, additional European Standards may apply. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest

32、 edition of the referenced document (including any amendments) applies.

34、re the carer performs an action to ensure that the child is secured in the restraint system 3.2 passive restraint system system where the carer does not perform an action to ensure that the child is secured in the restraint system 3.3 crotch restraint device passing between the legs of the child and

35、 preventing the child from slipping forwards out of the high chair 3.4 waist restraint rigid or flexible device(s), which when fastened, goes from one side of the high chair to the other passing in front of the childs waist or surrounding the childs waist 3.5 shoulder restraint device passing over t

36、he shoulders and connecting either to the crotch restraint or to the waist restraint BS EN 14988:2017EN 14988:2017 (E) 6 3.6 locking device component that maintains part(s) of the product in the position of use EXAMPLE Latch, a hook, an over centre lock. 3.7 operating device part of the locking mech

37、anism(s) or parking device(s) designed to be activated by the carer by one or several action(s) 3.8 parking device device intended to prevent rolling of castors/wheels 3.9 locking mechanism assembly consisting of one or more locking device(s) and one or more operating device(s) 3.10 junction line in

38、tersection 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 c

39、omponents (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-tighten

40、ing 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 sha

41、ll 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. BS EN 14988:2017EN

42、 14988:2017 (E) 7 NOTE For the purposes of uncertainty in measurements, test results are not considered to be adversely affected when the above tolerances are met. 4.4 Test sequence The tests in Clause 8 shall be carried out on the same high chair and in the order of the clauses of this standard. 4.

43、5 Determination of the junction line The junction line is shown in Figure 1 below. Where the backrest and the seat do not meet, the junction line is the projection of the backrest onto the seat (see Figure 1). Key LL junction line 1 backrest 2 seat Figure 1 Junction line When the seat unit is in the

44、 form of a hammock, a theoretical junction line, “LL”, shall be determined as shown in Figure 2. The junction line may vary when the backrest is adjusted in different positions.
