EN 913-2018 pdf download.Gymnastic equipment-General safety requirements and test methods.
Materials shall be selected and protected such that the structural integrity of the equipment manufactured from them is not affected before the next relevant maintenance inspection.
NOTE 1 The provisions relating to certain materials in this European Standard do not imply that other equivalent materials are unsuitable in the manufacture of multi-sports equipment.
The selection of materials and their use should he in accordance with the appropriate European Standards where applicable.
In the choice of a material or substance for equipment, consideration should be given to the eventual disposal of the material or substance having regard to any possible environmental toxic hazard.
NOTE 2 Information on the identification and classification of such substances can be found in the Regulation (EC) No 1272/2008 (classificatIon, packaging and labelling of dangerous substances and mixtures) as well as in the Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration. Evaluation. Authorization and Restriction of Chemicals (REACH).
5.2 Surface finish
There shall be no protruding nails, projecting wire rope terminations or pointed or sharp-edged components. Rough surfaces should not present any risk of injury. All welds shall be smooth. Protruding bolt threads within any accessible part of the equipment shall be permanently covered, e.g. dome headed nuts. Nuts and bolt heads that project less than 8 mm are permitted in non-accessible parts. provided they are free from burrs.
Corners, edges and projecting parts within the space occupied by the user that protrude more than 8 mm, and which are not shielded by adjacent areas that are not more than 25 mm from the end of the projecting part, shall be rounded off, The minimum radius of the curve shall be 3 mm.
Figure 1 shows examples of protection for nuts and bolts and permissible protruding parts. Figure 2 shows examples of non-permissible protruding parts.
This requirement is intended only to prevent injuries caused by unintended contact with components.
by design or through deflection or bending under load, no entrapment point shall be created by such movement.
These requirements shall be assessed by carrying out a visual inspection and measurement using the methods specified in Annex A.
No danger of head and neck entrapment is considered to exist where the lowest part of the circumference of an opening is less than 600 mm above floor level. Where an item of equipment may be used at different heights or in different orientations, all possible heights and orientations shall be considered.
5.3.2 Transport system
Where a transport system is used, it shall not be possible for the equipment to tip over when loaded at one end with a minimum weight of 75 kg.
When a transport system encounters a floor threshold the mechanism shall not be able to disengage or drop unintentionally.
5.3.3 Floor fixings
Any floor fixings shall be designed in such a way that they will not protrude from the floor level, nor provide openings equal to or greater than 8 mm in diameter, when the equipment is not attached to the floor.
5.4 StabilIty and strength
5.4.1 General
Unless specified elsewhere in individual equipment standards, verification of the stability and strength of equipment shall be achieved by engineering calculation or by testing in accordance with the procedures specified in Annex B.
5.4.2 StabilIty
For stability testing where the normal action produces a destabilizing force in a horizontal direction, e.g. vaulting, the theoretical horizontal test force shall be calculated using the formula given in &L. The calculation shall give a result which is  35 % of the self-weight of the equipment or 50 N, whichever is the greater.
Unless specified elsewhere in individual equipment standards, for equipment with unfixed body sections an actual test shall be carried out with a theoretical horizontal test force of 65 % of the theoretical test force calculated according to the formula given in BJA or 50 N, whichever is the greater. Unfixed body sections shall not become separated.EN 913-2018 pdf download.
