Figure II.6 – Revolving doorset, 4-leaf (normative) Low energy movement of pedestrian doors Low energy movement General The force required to prevent a stopped doorset from opening or closing any further – measured at the main closing edge in the direction of travel – shall not exceed 67 N at any point in the opening or closing cycle. The kinetic energy of a doorset in motion shall not exceed 1,69 J. Annex KK states the speed settings for various widths and masses of doorsets required to obtain results conforming to this requirement. In the event of any interruption of mains power or failure of the drive, it shall be possible to open the doorset with a manual force not exceeding 67 N to release a latch and 90 N to open the doorset, when the force is applied to the main closing edge in the direction of travel. Low energy movement of the doorset is generally not protected with additional protective devices because the kinetic energy levels are not considered to be hazardous. However, use of low energy doorset movement should only be considered when the risk assessment has taken account of elderly, frail and disabled users and indicates that the risk to these users is low. A static closing force up to 150 N is allowed: when the gap between the main closing edge and the counter-closing edge is 8 mm for swing doorsets; or during the last 50 mm for any type of sliding and folding doorsets. Additional requirements for low-energy movement of hinged and swing doorsets Opening time Doorsets shall open from closed to back check, or 80° whichever occurs first, in 3 s or longer as required in Table KK1. Back check shall not occur before 60° opening. If the doorset opens more than 90°, it shall continue at the same rate as back check speed. NOTE Back check – Back check is the checking or slowing down of the speed of doorset opening before being fully opened (also called open check). Closing time It shall be possible to adjust the doorset on site to close from 90° to 10° in not less than 3 s and from 10° to fully closed in not less than 1,5 s as required in Table KK.1. (normative) Speed setting for low energy movement of pedestrian doors Speed settings for low energy power operated swing doorsets Table KK.1 shows the minimum opening time (in seconds) to back-check or to 80° open or minimum closing time (in seconds) from 90° to 10° open for most common doorset widths and masses. Table KK.1 – Speed settings
The minimum opening time for doorsets of other widths and/or masses shall be calculated using the following formula: where t is the time, in s; D is the doorset width, in m; m is the mass of the doorset leaf, in kg; 2,26 is the conversion factor (units mKg½ s-1 ). Speed settings for low energy sliding doorsets Table KK.2 shows the minimum travelling time per doorset leaf referred to the doorset mass and the travelling distance per doorset leaf. Table KK.2 – Minimum travelling time per doorset leaf vs. mass of door leaf
NOTE For telescopic sliding doorsets, the travelling distance applies to the fast moving leaf. The maximum speed for doorsets of other masses shall be calculated using the kinetic energy formula, considering that the maximum admitted energy is 1,69 J: Ec = ½ m v2 = 1,69 (J) By knowing the leaf weight it is possible to calculate the maximum allowed speed as follows: where v is the speed, in m/s; Ec is the kinetic energy, in J (always 1,69 J); m is the mass of the doorset leaf, in kg. Time settings for other travelling distances per leaf and masses shall be calculated using the following formula: where t is the travelling time for opening or closing, in (s); D is 90 % of the travelling distance of the leaf, in (m); v is the doorset speed, in (m/s).

The mass is placed in the path of the driven part and the drive is operated, the driven part shall stop or reverse its movement before contacting the mass. The following inactive floor pad areas are excluded from this requirement: the last 38 mm on each side of the driven part opening width; 60 mm along the junction of floor pads joined together side-by-side with the longest dimension perpendicular to the driven part opening; 90 mm along the junction of floor pads joined together side-by-side with the longest dimension parallel to the driven part opening; 150 mm across the junction of floor pads meeting at the threshold. NOTE 1 The inactive floor areas of pressure sensitive pads are shown in Figure 102. DD.20.107.2 The drive is installed with a driven part . The force exerted by the drive is adjusted to the highest value if the force can be adjusted by the user during use or user maintenance . Otherwise, the force is adjusted according to the installation instructions. The drive is supplied at the most unfavourable voltage between 0,94 and 1,06 times rated voltage . The test of DD.20.107.2.1 is applied and if the drive is intended to be used with vertically moving driven parts having openings in which a 50 mm tube can be inserted, the test of DD.20.107.2.2 is applied for an opening movement; if the drive is an automatic drive , the test of DD.20.107.2.3 is applied. DD.20.107.2.1 The drive is operated to close and open the driven part from the fully open and fully closed positions. The forces between the leading edge and counter opposing edges shall not exceed 150 N during the first 5 s after the force has exceeded 25 N; 25 N thereafter; or 400 N during the first 0,75 s after the force has exceeded 150 N; 150 N during a further period of 4,25 s; 25 N thereafter; or for vertically moving driven parts used as a door; 600 N during the first 2 s after the force has exceeded 150 N for driven parts that do not swing outward and meet DD.20.107.2.3; 400 N during the first 2 s after the force has exceeded 150 N for driven parts that swing outward; 150 N during a further period of 3 s; 25 N thereafter. However, after 0,75 s, peaks lower than 400 N are allowed, if they are decreasing from one to the other, and the period of oscillation is 1 s, and the average force calculated over the remaining period of 4,25 s is 150 N. The force is measured by means of an instrument that incorporates a rigid plate having a diameter of 80 mm and a spring having a ratio of 500 N/mm ( 50 N/mm. The spring acts on a sensing element that is connected to an amplifier having a rise and fall time not exceeding 5 ms. For vertically moving driven parts , the values apply to the vertical component of the closing and opening forces and between any counter opposing edges of moving parts. For vertically moving driven parts , the force is measured on the leading edge of the driven part when the dimension of the gap is 50 mm; 300 mm; 500 mm; 2 500 mm or 300 mm below the maximum if this is less. For vertically moving driven parts , the force is measured at the following locations: in the centre of the leading edge; 200 mm from each end of the leading edge if this edge is longer than 800 mm. For horizontally moving driven parts , the force is measured on the leading edge of the driven part , at the following heights, when the dimension of the gap is 50 mm and 500 mm: 50 mm; 300 mm from the top, for driven parts between 1,2 m and 2,5 m in height; 2 500 mm, for driven parts more than 2,8 m in height; in the centre, for driven parts not more than 2,8 m in height. DD.20.107.2.2 Drives , intended to be used with a vertically moving driven part having openings in which a 50 mm diameter cylinder can be inserted, are subjected to an opening test with the driven part loaded with a mass of 20 kg 0,5 kg. The mass, having dimensions of approximately 200 mm 200 mm 200 mm, is fixed to the driven part in the most unfavourable place, with one edge adjacent to the bottom edge of the driven part . The drive is operated to open the driven part . If the bottom edge of the driven part moves more than 500 mm, the movement of the driven part shall stop before the test piece comes into contact with the lintel. DD.20.107.2.3 An obstacle as described in DD.20.107.1.1 except having dimensions of approximately 80 mm 300 mm and a height of 100 mm is placed on the ground and centrally along its 300 mm length across the plane of the driven part opening. The drive is operated to close the driven part from opening gaps of 100 mm, 1 000 mm and the fully open position of the driven part . The driven part shall not move or only move in the opening direction. The tests with this obstacle shall be made using the non-reflective and reflective sides in turn. The test is repeated from the fully open position with the obstacle positioned at 100 mm from each end of the driven part opening in turn. A cylindrical obstacle, having a diameter of 50 mm and a length of 850 mm, is suspended by one end at a height of 900 mm above the ground and centrally in the driven part opening. The drive is operated to close the driven part and the cylinder is swung across the driven part opening from an angle of 45°. The entrapment protection system shall cause the driven part to reverse its movement. DD.20.108 Entrapment protection systems shall provide an adequate level of protection in the event of a failure within the system installation wiring. Compliance is checked by the following test, unless the entrapment protection system is a biased-off switch . The drive is installed with a driven part and supplied at rated voltage . The drive is operated to close the driven part . During the movement, a short circuit or open circuit is simulated in the system installation wiring. Unless the entrapment protection system continues to operate normally, the driven part shall stop moving within one cycle of operation or the movement of the driven part shall only be controlled by a biased-off switch by the time it has completed its movement. The test is repeated during the opening movement of the driven part . If the drive is controlled by a programmable electronic circuit , the software shall contain measures to control the fault/error conditions specified in Table R.1 and is evaluated in accordance with the relevant requirements of Annex R.

For sensing devices using other technologies, this annex may be used as a guide. An entrapment protection system shall always be tested on a complete power operated doorset assembly. The CA reference body (see Figure FF.1a) is a box with the dimensions 0,7 m ( 0,3 m ( 0,2 m. Both the top side and two sides that meet are made of a material with a diffuse reflectance value in the range of 2 % to 5 % of the wavelength of the entrapment protection system transmitter (e.g. IC antistatic foam; see also Figure 3 of IEC 61496-3:2008 for further materials) while the other two sides are made of a material with a diffuse reflectance value in the range of 80 % to 90 % of the wavelength of the entrapment protection system transmitter (e.g. white paper). The base of the reference body is not defined as it does not serve any purpose in the test. The CB reference body (SEE Figure FF.1b) is made of a matt-black elastomer with a Shore-A hardness of 70 5 and a diffuse reflectance value in the range of 10 % to 90 % of the wavelength of the entrapment protection system transmitter. The reference body shall be detected and the doorset shall then either stop before it touches the reference body, or reverse or switch over to low-speed motion as described in the product documentation. Entrapment protection systems which do not move with the doorset leave(s) shall be tested using all relevant sides of the CA reference body. Dimensions in millimetres

This static force shall come down to 80 N after a total time Tt of maximum 5 s. However, after Td, peaks exceeding 150 N but lower than the admissible dynamic forces shown in Table 1 are accepted if: they are decreasing from one to the other; and the period of oscillation is 1 s; and the average force calculated over the period of Tt – Td is 150 N. Impact force measuring equipment The test equipment for measuring forces shall consist of the following parts: two contact areas with a diameter of 80 mm. The contact areas shall be made of a hard material with sufficient strength, e.g. steel; spring that gives the contact area a spring ratio of 500 N/mm 50 N/mm; load cell; time measuring device; measuring value display/measuring value output device. The measuring equipment shall comply with the following specification: rising/falling time of the load cell amplifier 5 ms; the equipment shall be able to give measured values with an accuracy of at least ( 5 % or ( 10 N, whichever is the maximum deviation; measurements to be given in graphical form or by displaying the values. Field impact force measuring equipment Field measuring equipment need not display the values and accuracy shall at least be ( 10 % or ( 20 N of measured values, whichever is the maximum deviation. Calibration shall be performed at least once per year.

The kinetic energy of a doorset in motion shall not exceed 1,69 J. Annex KK states the speed settings for various widths and masses of doorsets required to obtain results conforming to this requirement. In the event of any interruption of mains power or failure of the drive, it shall be possible to open the doorset with a manual force not exceeding 67 N to release a latch and 90 N to open the doorset, when the force is applied to the main closing edge in the direction of travel. Low energy movement of the doorset is generally not protected with additional protective devices because the kinetic energy levels are not considered to be hazardous. However, use of low energy doorset movement should only be considered when the risk assessment has taken account of elderly, frail and disabled users and indicates that the risk to these users is low. A static closing force up to 150 N is allowed: when the gap between the main closing edge and the counter-closing edge is 8 mm for swing doorsets; or during the last 50 mm for any type of sliding and folding doorsets. Additional requirements for low-energy movement of hinged and swing doorsets Opening time Doorsets shall open from closed to back check, or 80° whichever occurs first, in 3 s or longer as required in Table KK1. Back check shall not occur before 60° opening. If the doorset opens more than 90°, it shall continue at the same rate as back check speed. NOTE Back check – Back check is the checking or slowing down of the speed of doorset opening before being fully opened (also called open check). Closing time It shall be possible to adjust the doorset on site to close from 90° to 10° in not less than 3 s and from 10° to fully closed in not less than 1,5 s as required in Table KK.1. (normative) Speed setting for low energy movement of pedestrian doors Speed settings for low energy power operated swing doorsets Table KK.1 shows the minimum opening time (in seconds) to back-check or to 80° open or minimum closing time (in seconds) from 90° to 10° open for most common doorset widths and masses.
