This European Standard shall be given the status
14、 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of an identical text or by endorsement, at the latest by May 2009, and conflicting national standards shall be withdrawn at the latest by May 2009.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 is drawn to the possibility that some of the elements of this document may be the subject of pa
15、tent 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 of which deals with a particular type or a particular group of gymnastic equipment. The principa
16、l 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) requirements and test methods for endurance have been deleted. According to the CEN/CENELEC In
17、ternal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg,
18、Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. BS EN 915:2008EN 915:2008 (E) 4 1 Scope This European Standard specifies functional requirements (see Clause 3) and specific safety requirements in addition to the general sa
19、fety requirements in EN 913 (see Clause 4) which shall be read in conjunction with this standard. This European Standard is applicable to 2 types of asymmetric bars (see Table 1) intended for use under supervision of a competent person. 2 Normative references The following referenced documents are i
20、ndispensable for the application of this document. For dated references, only the edition cited applies.

25、 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 connections. 4.3 Stability When tested in accordance with 5.2, equipment shall not tip in any dire
26、ction 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 length. 4.4 Vertical stiffness and residual deflection When each bar is tested in accordance wi
27、th 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 tested in accordance with 5.4 using a vertical force of 2 850 N 50 N the equipment shall show no
28、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 longitudinal or the transverse direction when subjected to horizontal forces of 570 N 20 N in each
29、 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 force of 570 N 20 N in that direction. Transverse forces shall be applied to the middle of t
30、he 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 useful heights. 5.2 Determination of stability and rigidity 5.2.1 Principle A horizontal force
31、is applied to the equipment in the specified manner. BS EN 915:2008EN 915:2008 (E) 7 5.2.2 Apparatus A strap (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
32、avoid the sliding. Apply the specified horizontal force for a period of 65 s 5 s. Note any tipping of the equipment. 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,
33、report the deflection of the bar supporting cup in millimetres. 5.3 Determination of stiffness and residual 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 Appara
34、tus A strap (100 1) mm wide. 5.3.3 Test temperature Condition the equipment for a minimum of 3 h at a test temperature 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 de
35、flection at the centre of the bar. Remove the force. Measure the residual deflection 30 min 10+min after removal 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
36、in millimetres remaining 30 min 10+min after the removal of the load. BS EN 915:2008EN 915:2008 (E) 8 5.4 Determination of strength 5.4.1 Principle The equipment is loaded with a vertical force and examined for fracture or other damage. 5.4.2 Apparatus A strap (100 1) mm wide. 5.4.3 Test temperature
37、 Condition the equipment for a minimum of 3 h at a test temperature of (232)C. 5.4.4 Procedure Apply a vertical force at the centre of the bar for 65 s 5 s. Note any fracture, rupture, defects or other damage to the equipment. 5.4.5 Expression of results Express the strength by whether fracture or o
38、ther damage has occurred. 6 Instructions for use An information booklet shall be provided by the manufacturers containing the following: a) installation details; b) assembly details covering method of adjustment; c) equipment space; d) self weight of the equipment; e) maintenance details; f) warning
39、 notice that the equipment should be used under controlled supervision. 7 Marking Marking shall comply with EN 913.
