12、5(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for whic
13、h 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 collaborates closely with the International Electrotechnical Commission (IEC) on all ma
14、tters 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 approval criteria needed for the different types of ISO documents should be noted. This
15、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 subject of patent rights. ISO shall not be held responsible for identifying any or a
16、ll such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users a
17、nd does not constitute an endorsement.

18、information The committee responsible for this document is ISO/TC 136, Furniture. This second edition cancels and replaces the first edition (ISO 9221-2:1992), which has been technically revised. ISO 9221 consists of the following parts, under the general title Furniture Childrens high chairs: Part
19、1: Safety requirements Part 2: Test methods ISO 2015 All rights reserved v ISO 9221-2:2015(E) Introduction This part of ISO 9221 has been prepared in order to specify test methods to provide assurance that childrens high chairs comply with the requirements in ISO 9221-1.

27、cking mechanism mechanism composed by a locking device and one or more operating devices Note 1 to entry: An action deactivates the locking devices, e.g. pushing a button, pressing a lever or turning a knob. 3.10 junction line intersection of the seat and the backrest Note 1 to entry: See Figure 1.
28、Note 2 to entry: The method for determining the junction line can be found in 4.2. 4 General test conditions 4.1 Preliminary preparation The tests are designed to be applied to a high chair that is fully assembled according to the manufacturers instructions and ready for use. If the product can be c
29、onverted to other products not falling within the scope on this part of ISO 9221 (e.g. table and small chair, adult chair, swings, booster seats, etc.), these configurations shall not be tested according to this part of ISO 9221. The tests shall be carried out in indoor ambient condition with a temp
30、erature between 15 C and 25 C. If the temperature lies outside this range, its maximum and minimum shall be recorded in the test report. 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 i
31、nstructions 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. Knock-down fittings shall be tightened before testing.
32、 Further re-tightening shall not take place unless this is specifically required by the manufacturers instructions. 4.2 Determination of the junction line The junction line is shown in Figure 1. Where the backrest and the seat do not meet, the junction line is the projection of the backrest onto the
33、 seat (see Figure 1).2 ISO 2015 All rights reserved ISO 9221-2:2015(E) Key LL junction line 1 backrest 2 seat Figure 1 Junction line When the seat unit is in the form of a hammock, then a theoretical junction line, “LL”, is determined as shown in Figure 2. The junction line may vary when the backres
34、t is adjusted in different positions.

36、 2; Positioning of loading pads: 5 mm. The forces may be replaced by masses. The relationship of 10 N = 1 kg shall be used. 5 Test equipment 5.1 General Unless otherwise specified, test forces may be applied by any suitable device because results are dependent only upon correctly applied forces and
37、not upon the apparatus. The test forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic forces are applied. 5.2 Test dummy A rigid cylinder 200 mm in diameter and 300 mm in height, having a mass of 15 kg and with its centre of gravity 150 mm above its
38、base. All the edges of the cylinder shall have a radius of 5 mm. Two safety harness anchorage points shall be provided. These shall be positioned 150 mm from the base and 180 to each other around the circumference (see Figure 3).4 ISO 2015 All rights reserved ISO 9221-2:2015(E) Key 1 top edge of the
