EN 914-2020 pdf download.Gymnastic equipment – Parallel bars and combination asymmetric/parallel bars – Requirements and test methods including safety.
4.3 Protection against damaging the floor
The parallel bars and combination asymmetric/parallel bars shall not damage the floor.
4.4 Gap between the longitudinal/cross member
For Type 1, Type 2 and Type 3 when in use fill the gap between the longitudinal/cross member up to the highest level of the members. This can be achieved by mats according to EN 12503-1 and EN 12503-4 or by a platform base.
For Type 3 when used in competition, the whole framework shall be covered with mats of a total height of 20 cm according to EN 12503-1, and EN 12503-4:2016, Table 1, Type 6.
NOTE For competition FIG (Fédération Internationale de Gymnastique) rules will apply.
4.5 Transport equipment
If transport equipment is part of a parallel bar or a combination asymmetric/parallel bar, the transport equipment should be inside or underneath the framework, consisting of four swivelling transport rollers which are firmly connected.
5 Safety requirements
5.1 General requirements
Parallel bars and combination asymmetric/parallel bars shall comply with the requirements of EN 913, except insofar as they are modified by this European Standard.
5.2 Clear path between uprights
Fortypes land 2:
When tested in accordance with 6.2, the test pattern shall pass between the uprights.
For type 3:
When tested in accordance with 6.2 (note especially the modification of 6.2.1 and 6.2.3 br type 3), the
distance shall be  480 mm.
5.3 Entrapment
The entrapment requirements of EN 913 relate to the uprights, bars and connections between them. 5.4 Stability
For types 1 and 2:
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 ol the equipment with a minimum of 400 N. The force shall he applied at the middle of the bar and perpendicular to its length.
For type 3:
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 I and 2:
When each bar is tested in accordance with 6.4 using a force of (1 350 ± 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.
For type 3:
When each bar is tested In accordance with 6.4 using a force of(1 350 ± 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.
5.6 Strength
When each bar is tested In accordance with 6.5 using a vertical force of (2 850 ± 50) N, the equipment shall show no signs of fracture, rupture or defects.
5.7 Rigidity of framework
When tested in accordance with 6.3, the 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 ± 20) N in each of these directions. Transverse forces shall be applied to the middle of the bar and
perpendicular to its length. Longitudinal forces shall be applied along the axis of the bar.
6 Test methods
6.1 General
All loading tests shall be carried out with the bars set at their maximum useful height.
6.2 Determination of the clear path between uprights
6.2.1 Principle
The clear path between the uprights shall be assessed by placing a test pattern between them.
6.2.2 Apparatus
A test pattern as defined in Table 3 and Figure 3.
6.2.3 Procedure
Attempt to pass the test pattern between the uprights in contact with the cross member, whi’e keeping its plane perpendicular to the longitudinal axis of the bars and vertical.
6.2.4 Expression of results
State whether the test pattern can pass between the uprights.
6.3 Determination of stability and rigidity
6.3.1 PrincIple
A horizontal torce is applied to the equipment in the specitied manner.
6.3.2 Apparatus
A strap(100 ± 1) mm wide.
Only for type 3:
Any tractive force recording equipment, including load cells and recorders, which can monitor the tractive force exerted on the parallel bars is acceptable. The total system, detection and re-cording. shall be capable of measuring tractive forces of up to 5000 N to an accuracy of ± 1 %.
6.3.3 Test temperature
Condition the equipment for a minimum of 3 h at a test temperature of(23 ± 2) °C.
6.3.4 Procedure
For types 1 and 2:
Block the equipment on the ground to avoid sliding.
Apply the specified horizontal force in lateral direction away from the other bar for a period of
(65 ± 5) s.
Note any tipping of the equipment. When required, measure the deflection of the bar supporting cup in
the direction of the applied force.
For type 3:
Block the equipment on the ground to avoid sliding.EN 914-2020 pdf download.
