Furniture - Chairs and tables for educational institutions - Part 1: Functional dimensions

This part of European Standard EN 1729 specifies functional dimensions and markings for chairs and tables for general educational purposes in educational institutions. It includes furniture with fixed size mark and adjustable furniture as well as standing work height tables for use without chairs.
It applies to furniture for use with laptop computers or portable devices, but not to special purpose workstations, e.g. laboratories, ranked seating and workshops.
The standard does not apply to furniture used by teaching personnel.

Introduction This part of this European Standard is based on the principle that chairs and tables, intended for use in educational institutions for general-purpose education, should be designed to encourage good postures. This part of the standard takes selected national standards into consideration. It does not specify design, but only those dimensions, which promote good posture for either fixed height or adjustable furniture. The dimensional requirements of this standard permit various interpretations of design; hence customs, educational practices, technical and financial circumstances of individual countries can be satisfied.
The minimum dimensions specified are considered as the absolute minimum. Consequently, it is recommended to exceed these. It does not provide dimensional requirements for arm rests, but it does not preclude the use of armrests. Part 2 of this standard specifies safety requirements and test methods.

The standard does not apply to furniture used by teaching personnel. 2 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 2.1 median plane vertical plane passing through the geometric centre of the seat, dividing the seat from side to side into two equal parts (see Figure 1) 2.2 transverse plan vertical plane perpendicular to the median plane passing through the geometric centre of the seat, dividing the seat from front to rear (see Figure 1)

3 Functional dimensions for chairs and tables The functional dimensions and corresponding size marks and colour codes for chairs and tables shall be as specified in the normative Annexes A or B. The functional dimensions of standing height tables shall be as specified in normative Annex C. Adjustable and multi-size furniture shall fulfil the requirements specified in Annexes A, B or C.

Functional dimensions for chairs with slopes between -5 °and + 5 °and associated tables A.1 Functional dimensions and size marks for chairs The dimensions, angles, size marks and colour codes for chairs shall be as given in Table A1. The front edge of the seat shall be well rounded in the median plane. The front part of the seat may be curved in the median plane.
The upper and the lower edge of the backrest shall be rounded. Room for free movement of the buttocks shall be ensured. If the backrest extends below Point S, it shall be angled rearwards such as to maintain the buttock clearance zone as shown in Figure A.2. The side of the chair or seat shall not be raised to form a ridge higher than 15 mm than any lower point of the seat surface in the transverse direction of the seat. The determination of the functional dimensions of chairs is specified below. See also Figures A.1 to A.5. If the seat and/or back rest is adjustable or tiltable, the seat shall be set to horizontal or as close as possible and the back rest shall be set to vertical or as close as possible.
(h8) The height of the seat is determined on the median plane. It is the vertical distance between the front of the seat and the ground. See Figures A.3 and A.4.
(t4) The effective depth of seat is determined on the median plane as the horizontal distance between the front edge of the seat and the vertical projection from point S. See Figures A.1 to A.4. (b3) The width of the seat is determined as the horizontal distance between vertical lines through the side edges of the seat surface at a distance equal to half of t4. See Figures A.1 and A.2. (h6) The height of the foremost point of the backrest (Point S) is determined on the median plane. It is the vertical distance between the foremost point of the backrest and the seat surface. See Figures A.3 and A.4. (h7) The height of the backrest is a vertical distance determined on the med
