The tests carried out are designed to mimic the actions of a small child exploring a gate and its surroundings. For example, a child left to explore would attempt to climb over, through or under it, stick their fingers, arms, legs, head and toys through it, push and pull it very vigorously. Budding musicians will give it a good bash with anything to hand to make a great noise and next generation’s engineers will focus on prying apart the opening mechanism. Some children will use it as a teething aid by biting or mouthing it and all would probably love to hang onto the swinging part of the gate for a ride if given the opportunity.
