BS EN 914 This document specifies functional requirements (see Clause 4) and specific safety requirements in addition to the general safety requirements in EN 913 (see Clause 5)], which is read in conjunction with this standard.This document is applicable to three types of parallel bars (see Table 1) intended for use under supervision of a competent person.The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies. EN 913, Gymnastic equipment – General safety requirements and test methods
EN 12503-1, Sports mats – Part 1: Gymnastic mats, safety requirements EN 12503-4:2016, Sports mats – Part 4: Determination of shock absorption.When tested in accordance with 6.3, 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 bar and perpendicular to its length. When tested in accordance with 6.3 (note especially the modification of 6.3.4 Procedure for type 3), the tractive force shall be≥900 N.
5.5 Vertical stiffness and residual deflection Only for types 1 and 2: When each bar is tested in accordance with 6.4 using a force of (1 350土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. When each bar is tested in accordance with 6.4 using a force of (1 350土20) N, the deflection of each bar shall be a minimum of 50 mm and a maximum of 70 mm. The residual deflection shall be no greater than 1 mm.When each bar is tested in accordance with 6.5 using a vertical force of (2 850土50] N, the equipment shall show no signs of fracture, rupture or defects.BS EN 914 pdf downlaod.
