35、ried twice in accordance with the manufacturers instructions. 5.2 Test conditions The tests shall be carried out at a temperature of (20 5) C. BS EN 16120:2012+A1:2014 EN 16120:2012+A1:2014 (E)8 The tests are designed to be applied to chair mounted seats that are fully assembled and ready for use in
36、 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 in the static load tests shall be applied sufficiently slowly to ensure that negli
37、gible 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; Angles: 2 of the nominal angle; Positioning of loading pads: 5 mm; Duration of for
38、ces: 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 device which does not adversely affect the results. 5.5 Order of test Unless otherwise
39、 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 coatings of paint, varnish, lacquer, polymer and similar coatings on exterior surfa
40、ces shall not exceed the following amounts: Antimony: 60 mg/kg Arsenic: 25 mg/kg Barium: 1 000 mg/kg Cadmium: 75 mg/kg Chromium: 60 mg/kg Lead: 90 mg/kg Mercury: 60 mg/kg Selenium: 500 mg/kg These limits shall be verified in accordance with the test method given in EN 71-3:1994. Where a surface is c
41、oated with a multi-layer of paint or similar coating, the test sample shall not include the base material. BS EN 16120:2012+A1:2014 EN 16120:2012+A1:2014 (E)9 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 eff
42、ect. These requirements apply to parts with an area greater than 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 adjus
43、ted shall have locking mechanism(s), complying with 8.1.2, to maintain 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 no
44、rmal use. Chair attachment systems shall not be considered as locking 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 mech
45、anisms, one of the following conditions shall be fulfilled before 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 le
46、ast two consecutive actions, the first of which shall be maintained while the second is carried out, or d) height adjustment requires at least two independent and simultaneous actions. Inflatable systems are excluded from the requirements of this clause. Products that in every position of use have t
47、o be removed from the adult chair to adjust the height or to fold the base for storage are excluded from the requirements of this clause. 8.1.3 Test method for the durability of the locking mechanisms Operate 300 times any locking mechanism(s).
