This European Standard shall be given t

15、he 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of an identical text or by endorsement, at the latest by May 2009, and conflicting national standards shall be withdrawn at the latest by May 2009.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 is drawn to the possibility that some of the elements of this document may be the subj

16、ect of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 914:1996. This European Standard is one of several standards, each of which deals with a particular type or a particular group of gymnastic equipment. The

17、 principal changes from the previous edition of EN 914 are as follows: a) the dimensions in Tables 2 and 3 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.

30、e bar at the supporting cup point shall not deflect by more than 20 mm in the longitudinal or the transverse direction when subjected to a horizontal force of 570 N 20 N in each of these directions. Transverse forces shall be applied to the middle of the bar and perpendicular to its length. Longitud

31、inal 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 height. 5.2 Determination of the clear path between uprights 5.2.1 Principle The clear path between the uprights shall be assessed by pl
