AS 4685.6:2021 pdf free.Playground equipment and surfacing Method 6: Additional safety requirements and test methods for rocking equipment (EN 1176-6:2017, MOD).
4 Safety requirements
4.1 General
Unless otherwise specified, seesaw/rocking equipment shall conform to EN 1176-1.
4.2 Free height of fall
When measured at extreme positions of movement, the centre of the seat/stand shall have a maximum free height of fall in accordance with Table 1.
4.3 Seat/stand slope
When tested in accordance with normative Annex B, the maximum slope at the seat/stand shall be in accordance with Table 1.
4.4 Pinch, crush
When tested in accordance with normative Annex C, gaps in all accessible joints and supporting components shall conform to EN 1 176-1:2017, 4.2.6 and 4.2.7.
NOTE This requirement is intended to prevent pinching and crushing.
4.5 Restraint of motion
The motion of equipment should be regulated towards the extremities of movement so that no sudden stop or sudden reversal of the motion can occur, e.g. damping.
NOTE 1 The damping effect can be:
a) constant, where the effect is constant throughout the entire range of movement; or
b) varied, where the effect depends on the speed, mass and/or position of the rocking parts of the equipmenL NOTE 2 This is to reduce the risk of spinal injuries due to sudden shock load, e.g. by use of a spring or other damping elements.
4.6 Foot rests
Where foot rests are provided they shall be firmly fixed and unable to rotate without using tools.
When tested in accordance with normative Annex E, no part of the foot rest shall project beyond the outer face of the gauge.
4.7 Hand supports
They shall be firmly fixed and unable to rotate without using tools.
For equipment accessible for use by younger children, the grip requirements should be selected from the lower end of the range; maximum diameter/cross-section of 30 mm is recommended.
When tested in accordance with normative Annex E, no part of the hand support shall project beyond the outer face of the gauge.
NOTE The intention of this requirement is to reduce the hazard of eye injury from the ends of projecting hand supports, by maintaining a cross sectional area of at least 15cm2.AS 4685.6 pdf download.
