EN 913:1996, Gymnastic equipment一General safety requirements and test methods. 3.3 Performance of padded box top When tested according to EN 913:1996, annex C using a drop height of 300 mm, the peak acceleration shall not exceed 500 m/s2 (50 g). 4 Safety requirements 4.1 General Vaulting boxes shall comply with the requirements of EN 913, except insofar as they are mdified by this European Standard. 4.2 Stability When tested according to 5.1, the vaulting box shall not rotate about the base, nor shall any of the sections sepa- rate in normal use when subjected to a horizontal force representing 20 % of the self weight of the vaulting box. 4.3 Strength When tested according to 5.2, the vaulting box or any vertical sided individual section shall show no sign of loose bonds, breaking or cracking. 4.4 Durability of construction When tested according to 5.3, sections shall not show any loose joints, breakage, cracking or change in diagonal dimensions greater than 3 mm. 5 Test methods 5.1 Determination of stability 5.1.1 Principle A horizontal force is applied to the top of the equipment and any movement of the top is noted. 5.1.2 Test temperature Condition the equipment for a minimum of 3 h at a temperature of (23土2) °C. 5.1.3 Procedure Carry out the test at maximum height. Prevent the vaulting box from sliding, see Figure 1. Apply a horizontal force calculated from 20 % of the self weight of the equipment with a minimum of 70 N to the highest point in the centre of the top (see Figure 1). Note the first movement of the top of the vaulting box. 5.1.4 Expression of results Express the level of stability by noting if rotation has occurred. 5.2 Determination of strength 5.2.1 Principle Load the equipment with a calculated vertical force and examine for fracture or other damage. 5.2.2 Apparatus A rigid plate of dimensions (200 mm x 200 mm x 10 mm)士1 mm with a radius of the lower edges of minimum 3 mm. 5.2.3 Test temperature Condition the equipment for a minimum of 3 h at a test temperature of (23土2) °C. 5.2.5 Expression of results Express the strength by whether loose bonds, breaking or cracking has occurred. 5.3 Determination of durability of construction 5.3.1 Principle A section is dropped on a concrete floor from a specified height and examined for damage and the pre-test and post-test variation of diagonal dimensions is measured and the difference is determined. 5.3.2 Procedure Before testing, measure the diagonal dimensions of a section. Drop the section onto a concrete floor, from a mini- mum height of 120 mm perpendicular to the section’s diagonal axis. Carry out the test five times for each corner, taking diagonally opposite corners in turn. 5.3.3 Expression of results Note any breakage or loose and easily moveable connections. Record the pre-test and post-test variation of diago- nal dimensions in millimetres.EN-916 pdf download.
