15、ment”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2009, and conflicting national standards shall be withdrawn at the latest by May 2009. Attention
16、 is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 915:1996. This European Standard is one of several standards, each
17、of which deals with a particular type or a particular group of gymnastic equipment. The principal changes from the previous edition of EN 915 are as follows: a) the dimensions in Table 2 have been adapted; b) safety requirements and test methods have been modified; c) entrapment has been included; d
18、) requirements and test methods for endurance have been deleted. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Fin
19、land, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

27、metric bars shall comply with the requirements of EN 913, except insofar as they are modified by this European Standard. 4.2 Entrapment The entrapment requirements of EN 913 relate to the uprights, horizontal adjustment devices and connections between them as well as bars but excluding the bar conne
28、ctions. 4.3 Stability When tested in accordance with 5.2, equipment shall not tip in any direction when subjected to a horizontal force representing 40 % of the self weight of the equipment with a minimum of 400 N. The force shall be applied at the middle of the upper bar and perpendicular to its le
29、ngth. 4.4 Vertical stiffness and residual deflection When each bar is tested in accordance with 5.3 using a force of 1 350 N 50 N, the deflection of each bar shall be a minimum of 40 mm and a maximum of 100 mm. The residual deflection shall be no greater than 1 mm. 4.5 Strength When each bar is test
30、ed in accordance with 5.4 using a vertical force of 2 850 N 50 N the equipment shall show no signs of fracture, rupture or defects. 4.6 Rigidity of framework For type 1 equipment when tested in accordance with 5.2, the bar at the supporting cup point shall not deflect by more than 20 mm in the longi
31、tudinal or the transverse direction when subjected to horizontal forces of 570 N 20 N in each of these directions. For type 2 equipment when tested in accordance with 5.2, the bar shall not deflect by more than 20 mm at the attachment points in the transverse direction when subjected to a horizontal
32、 force of 570 N 20 N in that direction. Transverse forces shall be applied to the middle of the bar and perpendicular to its length. Longitudinal forces shall be applied along the axis of the bar. 5 Test methods 5.1 General All loading tests shall be carried out with the bars set at their maximum us
33、eful heights. 5.2 Determination of stability and rigidity 5.2.1 Principle A horizontal force is applied to the equipment in the specified manner.

34、 (100 1) mm wide. 5.2.3 Test temperature Condition the equipment for a minimum of 3 h at a test temperature of (23 2) C. 5.2.4 Procedure Block freestanding equipment (type 1) on the ground to avoid the sliding. Apply the specified horizontal force for a period of 65 s 5 s. Note any tipping of the eq
35、uipment. When required, measure the deflection of the bar supporting cup in the direction of the applied force. 5.2.5 Expression of results Report whether tipping has occurred. When required, report the deflection of the bar supporting cup in millimetres. 5.3 Determination of stiffness and residual
36、deflection 5.3.1 Principle A vertical force is applied to the centre of each bar and any deflection is measured. The force is then removed and any residual deflection is measured. 5.3.2 Apparatus A strap (100 1) mm wide. 5.3.3 Test temperature Condition the equipment for a minimum of 3 h at a test t
37、emperature of (23 2)C. 5.3.4 Procedure Apply a vertical force at the centre of the bar for 65 s 5 s. Measure the position of the loaded component from any convenient datum point. Record the deflection at the centre of the bar. Remove the force. Measure the residual deflection 30 min 10+min after rem
38、oval of the force. Record any residual deflection. 5.3.5 Expression of results Express stiffness as the deflection under load in millimetres. Express the residual deflection as the deflection in millimetres remaining 30 min 10+min after the removal of the load. Licensed Copy: Wang Bin, ISO/EXCHANGE
