36、e mounted on a cycle, the tester shall refer to the purchase information (see 13) and instructions for use (see 14). It is allowed to use any cycle that is suitable according to this information. Each test shall be conducted with the seat in the most onerous condition for that test. 5.2 Tolerances a
37、nd test conditions Unless otherwise stated the following tolerances shall be used : All forces shall have an accuracy of 5%. All masses shall have an accuracy of 1 %. All dimensions shall have an accuracy of 1,0 mm. All time measurements shall have an accuracy of 1s. All angles shall have an accurac
38、y of 1. All frequencies, amplitudes shall have an accuracy of 5 %. The seat shall be conditioned at a temperature of (23 5) C for at least 2 h prior to test. All tests shall be carried out at a temperature of (23 5) C unless otherwise specified. 5.3 Order of tests The test shall be carried out in th
39、e order that they appear in this document. All tests shall be performed on one seat. EN 14344:2004 (E) 9 6 Construction 6.1 Dimensions 6.1.1 Seating area and footrests 6.1.1.1 Requirements for seating area and footrests The dimensions of the main child supporting areas of the seat shall comply with
40、items a, b, c, d, e and f in Table 2, when measured in accordance with 6.1.1.3. NOTE 1 The reference plane of this measuring instrument lies approximately 55 mm above the sitting area, and measurements are made at or relative to this plane. Dimensions c and d in Table 2 are therefore some 55 mm less
41、 than the full dimensions of these features, whereas the dimensions in f are greater by a similar amount. NOTE 2 The items h, i and j are not requirements but necessary points for the measuring instrument. NOTE 3 For item f : the length of the lower leg is adjustable. EN 14344:2004 (E) 10 Table 2 Di

44、 The dimensions of the seat shall be checked using the measuring instrument described in Annex A. Mount the seat on a cycle or similar fixture, with any padding supplied with the seat fitted in accordance with the manufacturers instructions. Place the measuring instrument in the seat with the point
45、A touching the centre of the lower backrest area. Load the measuring instrument with a mass of 5 kg centred above point C and adjust the orientation of the seat until the reference plane of the instrument becomes horizontal. NOTE When measuring the padded areas it is permitted that the measuring ins
46、trument is loaded to compress any padding in a similar way to a child sitting in the seat. EN 14344:2004 (E) 11 6.1.1.3 Test method for seating area and footrest Take measurements relative to the points on the reference plane of the measuring instrument as follows (see Figure A.2) : a) measure the i
47、nside width of the seat, through point B ; check that this complies with the requirements given in Table 2, line a ; b) slide the 60 mm by 15 mm diameter pillar along the thigh scale until it touches the edge of the seat. The seat length is the distance between the edge of this pillar and point A ;
48、check that this complies with the requirements given in Table 2, line b ; c) measure to the top centre of the backrest from point A. Take the linear distance between these two points using a calliper, or, if using the measuring instrument as shown, calculate from the vertical and horizontal displacement relative to point A ; check that this distance complies with the requirements given in Table 2, line c. If the child seat is fitted with an adjustable headrest measure to the t
