7.3.1.1 Requirement
There shall be no accessible completely bounded openings in rigid materials between 7 mm and 12 mm unless the depth is less than 10 mm or unless the shape assessment probe, see 4.1.2, enters, when tested in accordance with 7.3.1.2.
There shall be no accessible openings in mesh that allow the test probe for mesh, see 4.1.1, to penetrate up to the 7 mm diameter section, when tested in accordance with 7.3.1.2.
The test shall be carried out with the product In any Intended position of use without any test mass and with test mass A (4.2.1).
7.3.1.2 Test method
Check whether the 7 mm probe, 4.1.1, with an applied force of up to 30 N, enters 10 mm or more into any accessible completely bounded opening in any possible orientation.
If the 7 mm probe enters 10 mm or more, then the 12 mm probe, 4.1.1, shall also enter 10 mm or more
with an applied force of up to 5 N. If the 7 mm probe enters with an applied force of up to 30 N but the
12 mm probe does not enter 10 mm or more with an applied force of up to 5 N, check whether the
12 mm shape assessment probe (see 4.1.2) enters 10 mm or more with an applied force of up to 5 N.
Check whether the test probe for mesh, 4.1.1, with an applied force of up to 30 N, penetrates accessible openings in mesh up to the 7 mm diameter section.
7.4 Hazards due to moving parts
7.4.1 Requirements for compression points
After the product has been set up for use in accordance with the manufacturer’s instructions, there shall be no accessible compression points which can close to less than 12 mm unless they are always less than 5 mm, as the result of:
a) the movement of the product; or
b) the movement of body weight by the child using the product; or
c) the application of an external force (either unintentionally by the carer, or by a powered mechanism).
Movement due to elasticity of materials shall not be considered as a compression hazard.
The area of contact between the product and the surface on which the product is fixed is excluded from this requirement.
7.6.2 Test methods
7.6.2.1 Assessment of child’s ability to grip components
A component is considered to be able to be gripped if the child can grip the component between its thumb and forefinger or between its teeth.
Where it is difficult to assess whether a child can grip a component, establish whether it can be gripped by inserting the feeler gauge (4.4) between the component and the underlying layer or body of the product at an angle between 00 and 10° from the surface of the underlying layer or product, using a force 01(10 ± 1) N. lithe gauge can be inserted more than 2 mm. the component is considered to be able to be gripped by the child.
7.6.2.2 Torque test
Apply a torque gradually to the component within a period of 5 s in a clockwise direction until either:
a) a rotation of 1BO° from the original position has been attained; or
b) a torque of 0,34 Nm is reached.
The maximum rotation or required torque shall be applied for 10 s.
The component shall then be allowed to return to a relaxed condition and the procedure repeated in an anticlockwise direction.
Where projections, components or assemblies are rigidly mounted on an accessible rod or shaft, designed to rotate together with the projections, components or assemblies, during the test the rod or shaft shall be clamped to prevent rotation.
If a component attached by a screw thread becomes loosened during application of the required torque, the torque shall continue to be applied until the required torque is exceeded or the component disassembles or it becomes apparent that the component will not disassemble.
When using clamps and test equipment, care shall be taken not to damage the component to be tested which may affect the test results.
7.6.2.3 Tensile test
Attach a suitable clamp to the component, taking care not to damage the component to be tested which may affect the test results.
Fasten the component in a tensile testing machine and apply a tensile force of up to 90 N to the component to be tested. Apply the force gradually within a period of 5 s and maintain it for 10 s.BS/EN 17022-2018 pdf download.
