Teddy torture leads to testing times in toy town
Teddy bears are being "tortured" in order to meet the stringent demands of European Commission (EC) directives. Teddy bear body parts, such as glass eyes and plastic noses, are being pulled and twisted by mechanical multi-jawed grips to see how well they will cope in the rigorous world of the nursery playroom.
"Once children have opened their Christmas presents it is amazing what their fingers, and indeed teeth, will try to do to their new toys," says Chris Grant from 'teddy torturing' company Mecmesin Ltd. in Horsham, West Sussex (UK). To the horror of arctophiles everywhere, bears are strapped into a testing rig and have their body parts mechanically pulled from them at forces of up to 90 Newtons (about 20lbs of force) over a 5 second period. Machines are also used to twist and turn the body parts to make sure that the cuddly toys can withstand even the most ferocious temper tantrum.
Other tests included in the UK's Toy (Safety) Regulations Act cover the mechanical and physical properties of the toys as well as the flammability and the likely migration of toxic substances. Despite frequently being labelled as a teddy torturer, Grant has few reservations about the validity of the role that he and his company has to play, "Few would argue with the fact that in order to safeguard children, cuddly toys must continue to 'suffer'."
