EN 914-2008 pdf download.Gymnastic equipment – Parallel bars and combination asymmetric/parallel bars – Requirements and test methods including safety.
This EN 914 specifies functional requirements (see Clause 3) and specific safety requirements in addition to the general safety requirements in EN 913 (see Clause 4), which shall be read in conjunction with this standard.
This European Standard is applicable to 2 types of parallel bars (see Table 1) intended for use under supervision of a competent person.
2 Normative references
The following referenced documents are indispensable for the application 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
3 Requirements
3.1 Classification
Parallel bars and combination asymmetric parallel bars shall be classified by the design (types and sizes) as shown in Table 1
4 Safety requirements
4.1 General requirements
Parallel bars and combination asymmetnciparaiiei oars shall compiy wiih me requiremenis OT N except
insofar as they are modified by this European Standard.
4.2 Clear path between uprights
When tested in accordance with 5.2 the test pattern shall pass between the uprights.
4.3 Entrapment
The entrapment requirements of EN 913 relate to the uprights, bars and connections between them.
4.4 Stability
When tested in accordance with 5.3, 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.
4.5 Vertical stiffness and residual deflection
When each bar is tested in accordance with 5.4 using a force of 1 350 N ± 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 1mm,
4.6 Strength
When each bar Is tested in accordance with 5.5 using a vertical force of 2 850 N ± 50 N the equipment shall
show no signs of fracture, rupture or defects.
4.7 Rigidity of framework
When tested in accordance with 5.3, 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 N ± 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.
5 Test methods
5.1 General
All loading tests shall be carried out with the bars set at their maximum useful height.
5.2 Determination of the clear path between uprights
5.2.1 Principle
The clear path between the uprights shall be assessed by placing a test pattern between them.
5.2.2 Apparatus
A test pattern as defined in Table 3 and Figure 3.
5.2.3 Procedure
Attempt to pass the test pattern between the uprights in contact with the cross member, while keeping its
plane perpendicular to the longitudinal axis of the bars and vertical.
5.2.4 Expression of results
State whether the test pattern can pass between the uprights.
5.3 Determination of stability and rigidity
5.3.1 PrincIple
A horizontal force is applied to the equipment in the specified manner.
5.3.2 Apparatus
A strap (100 ± 1) mm wide.
5.3.3 Test temperature
Condition the equipment for a minimum of 3 h at a test temperature of (23 ± 2) °C.
5.3.4 Procedure
Block the equipment on the ground to avoid sliding.
Apply the specified horizontal force 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.
5.3.5 Expression of results
Report whether tipping has occurred. When required, report the deflection of the bar supporting cup in millimetres.
5.4 Determination of stiffness and residual deflection
5.4.1 Principle
A vertical force is applied to the centre of each bar and any deflection is measured. The force is then removed and any residual deflection is measured.EN 914-2008 pdf download.
