12、t. 7.2 Procedure Use sample A1. Inspect the rolls for surface imperfections. Inspect and ensure that the installed hardware set is in accordance with the manufacturers instructions. Install the hardware for Lift the procedure is as follows: initial position of the active sash is the locked closed po
13、sition. hardware is moved jerk and jolt-free into an operating position, in which the tilted position is reached. In this position the sash remains for 1 s so that it can settle. hardware is brought back to the initial position; this is the locked closed position. Then the hardware remains in this i
14、nitial position for 1 s and can settle before the next test cycle is started. NOTE The velocity with which the hardware is operated results from the predetermined rate of 200 cycle/h, the indicated interval times and the jerk and jolt-free initiation of all movements. 7.3.1.1.2 Tilt cycles on hardwa
15、re without positive control Tilt cycles for hardware with tilt function and without positive control shall be at a rate (rate) of 200 cycles/h; the procedure shall be as follows: initial position of the active sash is the locked closed position. BS EN 13126-16:2008EN 13126-16:2008 (E) 12 hardware is

Move the active sash away from the opening position towards the closed position, whereby the acceleration shall be in a jerk and jolt-free manner. 100 mm before reaching the closed position, the active sash shall have a velocity of 0,8 m/s. After havin
38、g reached the closed position, the active sash is allowed to settle. Test the sash 3 times. NOTE 1 After having reached the closed position, the sash can be in the sliding, tilted or closed position while settling. NOTE 2 If the hardware is equipped with a brake mechanism, the velocity of the active
39、 sash while moving the 100 mm up to the closed position may be reduced during cycling. NOTE 3 If the active sash reaches the tilted position instead of the closed position, it should be tested in accordance with the previous procedure. In this case the closed position should be replaced by the tilte
40、d position. 7.4.2 Procedure into the opening position Use sample A1. This procedure shall use an active sash test mass of 50 % of the maximum test mass. The active sash is moved away from the closed position towards the opening position, whereby the acceleration shall be in a jerk and jolt-free mann
41、er to 100 mm before reaching the opening position. The active sash shall have a velocity of 0,8 m/s. The sash shall collide with the buffer stop at a speed of 0,8 m/s (see Figure A.2).
