EN 916-2003 pdf download.Gymnastic equipment-Vaulting boxes – Requirements and test methods including safety.
Vaulting boxes shall comply with the requirements of EN 913, except insofar as they are modified by this European Standard.
This EN 916 specifies functional requirements (see clause 3) and specific safety requirements for five types of vaulting boxes (see Table 1) in addition to the general safety requirements in EN 913.

3 Requirements
3.1 ClassifIcation
Vaulting boxes shall be classified by the design (types) as shown in Table 1.
4.2 Stability
When tested according to 5.1, the vaulting box shall not rotate about the base, nor shall any of the sections separate 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 shail 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±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 stabdity 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) ± 1 mm with a radius of the lower edges of minimum
3mm.
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
5.2.4.1 Whole vaulting box
Apply a vertical force of 2 850 N at the centre of the top of the equipment for 1 mm S.
Note any loose bonds, breaking or cracking of the equipment.
5.2.4.2 Sections
Apply a vertical force of 1 700 N at the centre of each long side of the equipment for 1 mm
Note any loose bonds. breaking or cracking of the equipment.
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 pie-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 minimum 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 diagonal dimensions in millimetres.
6 Warning
The manufacturer shall provide a warning notice that the equipment should be used under controlled supervision.
7 Marking
a) marking shall comply with EN 913;
b) type according to Table 1.EN 916-2003 pdf download.
