10、 be immersed in water to a maximum depth of 2 in (50.8 mm), with its center resting on a hard flat surface. A 200 Ib (90.7 kg) weight with a smooth metallic face 1 in (25.4 mm) wide shall be placed without impact on a 1 in (25.4 mm) section at the center of the hose. After one minute, the weight sha
