4.4 TEST PROCEDURE
4.4.1 Attack on hinged security screen doors
4.4.1.1 Ailack upon locks
The point of application of the lever shall he ithin 50 mm of the centre of the lock bolt and shall bear on the lock body. For the purpose of the test, the lever shall be inserted between the door and the jamb so that the tip of the lever is aligned with the back edge of the doorframe (see Figure 4.5). The test shall be applied to all locking points. If the test cannot he applied within 50 mm from a locking point, the test shall be applied as close as possible to the locking point.
Ilie lever shall be inserted using reasonable manual force and manipulation without the aid of any other hand tools. If the necessary depth cannot be achieved within three minutes. the test shall be continued at the insertion depth obtained. Alternatively, the lever may be mechanically inserted to a maximum force of 980 N. or until the lever reaches the door or window grille stop.
Whilst performing this test, the lever shall he secured in relation to the pivot point with a hold in force of 700 N.
Should the lever he displaced during the test, the above directions shall he repeated a second time.
Should the lever disengage the second time, the next test shall be carried out.
NOTE: The lever should be restrained in a manner that prevents injury to test personnel.
Whilst performing this test, the lever shall be secured in relation to the pivot point and restrained at that point to prevent axial displacement of the lever away from the doorframe.
NOTE: The intention is to stop the lever from slipping out of thc door frame during testing.
When testing type 3 products,if a gap of 15 mm x 90 mm is achieved，which is largeenough to allow the insertion of the testing pull bracket, a pull test shall be required.
The lever shall then be subjected to a force that will result in a maximum torque of 450 Nmbeing applied to the lever about the axis of rotation,for the full movement arc of the lever(see Figure 4.2). The test shall be repeated at all locking points on the door.
NOTE: If,in seeking to apply the torque specified, the full torque value has not been achievedafter the lever has been rotated through 80° from the normal to the door, this will not constitute afailure of the test provided that the requirements of this Clause are met.
The load shall be applied for 20 s after the maximum load or displacement is reached.
