EN 71 Toys Testing Equipment Liquid Leakage Testing Needle
Procedure Within 30 s of removing the toy from conditioning, apply a force of (5+0.50)N to the external surface of the toy through a steel needle with a diameter of 1 mm 0,1 mm and with a tip radius of 0,5 mm 0,05 mm.
How do you do a leakage test? The leak test is performed by immersing a part, usually a sandwich composite structure, in a hot water tank. The temperature of the water induces the expansion of air in the structure, and if a crack or a delamination is present, gas bubbles escape the structure and are immediately detected by visual inspection.
