1 Scope
This document is applicable to rocking equipment which is used as playground equipment for children, as defined in 3.1. Where the main play function is not rocking, the relevant requirements in this document may be used, as appropriate. This document specifies additional safety requirements and test methods for seesaws and rocking equipment intended for permanent installation for use by children. It is intended to provide protection to the user against possible hazards during use. NOTE Guidance for assessing the safety of other forms of seesaw/rocking equipment is given in informative Annex A.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1176-1 and the following apply. 3.1 rocking equipment seesaw (hereinafter referred to as equipment) equipment that can be set in motion by the user and is generally characterized by a rigid element that rocks about a central support Note 1 to entry: The equipment can have one or several seats or stands. Note 2 to entry: Figure 1a) shows the principle components for rocking equipment. Figure 1b) shows the principle components for seesaws. Note 3 to entry: The seesaw/rocking movement depends on the type and configuration of fixture (see Figures 2 to 7).3.8 equipment body main moving part connected to the equipment supporting component(s) 3.9 supporting component component which connects the equipment body to the anchorage 3.10 Anchorage means by which stability and fixation to the ground/surface is made 3.11 damping combined effect of the supporting component(s) that moderates the speed at which the equipment can move and the reduction of shock effects at the outer positions of the equipment 3.12 range of movement maximum horizontal and/or vertical deviation of the seat/stand during use from the centre point at equilibrium position
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 1176-1:2017, 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 equipment. 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.
