According to DIN EN 455-1, a water leak test can be performed to verify the watertightness of disposable gloves. Using a vertical tube, 1000 ml of water at a temperature between 15 °C and 35 °C is filled into the glove to be tested. The glove is immediately visually inspected for leaks. The glove is considered non-watertight as soon as water leakage occurs. After 2 to 3 minutes, the glove is visually inspected again.
