Where dimensions are stated as ranges, the measured dimension shall be any value in this range. All accessible edges shall be rounded or chamfered. 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 zone as shown in Figure A.3. Raised edges and surfaces shall not dig into thighs. This applies to points or edges on the seat surface or frame in front of the position indicated by the rear pins on the SCMD, outside the planes through the rear pins which are parallel to the median plane, as shown by the shaded area in Figure A.1. This requirement is fulfilled when these points are not higher than 15 mm above the lowest point on the seat surface in the planes through the rear pins and parallel to the median plane for size marks 0 to 3 and 25 mm above the lowest point for size marks 4 to 7.

shall be determined by the SCMD on the chair under load. On the SCMD, it is the angle between the vertical arm when it is inclined at the angle of the backrest and the top of the base plate. See Annex F and Figure F.1, Figure A.5 and Figure A.6. (o) The width of the armrest is the minimum distance between the sides of the armrest/armrest pad, measured at 5 mm below the top surface of the armrest. See Figure A.4. (p) The height of the armrest above the seat shall be determined by the SCMD on the chair. On the SCMD, it is the vertical distance between the top of the armrests and the bottom of the rear pins of the SCMD. See Annex F and Figure F.1 and Figure A.4. (q) The distance from the backrest to the front of the armrest is the maximum horizontal distance between Point S and the front of the top of the armrest, the position of which is determined by the SCMD. See Figure A.4. (r) The width between the armrests is the minimum horizontal distance between the armrests/armrest pads. See Figure A.4. (n) The length of the armrest is the greatest length in the fore and aft direction of the armrest horizontally within 20 mm below the highest point. See Figure A.4. (x) The distance between Point S and the back of the seat pad is the horizontal distance on the median plane between the rear edge of the seat and the vertical projection of Point S. It shall be determined only if the back of the seat pad does not extend behind Point S. See Figure A.5 and Figure A.6. SIST EN 1729-1:2016

See also Figure B.2, Figure B.3, Figure B.4 and Figure B.5. If the seat and/or backrest is adjustable or tiltable, the seat shall be set to horizontal or as close as possible to horizontal and the backrest shall be set to vertical or as close as possible to vertical. Guidance for the calculation of the height of chairs and tables can be found in Annex H (informative).

is defined as the angle between the rear part of the seat and the backrest. It is measured on the median plane, as the angle between the backrest and the line passing through the upper part of the rear edge of the seat and the apex of the seat. See Figure B.5. (o) The width of the armrest is the minimum distance between the sides of the armrest/armrest pad, measured at 5 mm below the top surface of the armrest. See Figure B.4. (p) The height of the armrest above the seat is the vertical distance between the top of the armrest and the apex of the seat. See Figure B.4.
