29、 A non-reusable container for breathable gas mixture which is opened not by a valve but by actuating a mechanism which allows the contents of the cartridge to transfer fully into the BC. 3.14 breathing mixture Air or a gas mixture indicated by the manufacturer providing an oxygen partial pressure hi
30、gher than 0,16 bar and having a percentage of oxygen not higher than 40 % by volume. 3.15 rated intermediate pressure The maximum rated intermediate pressure as indicated in the instructions for use of the BC as maximum working pressure for the mechanical inflator. 4 Requirements 4.1 General When te
31、sted in accordance with 5.7 and 5.11, the BC shall not give evidence of any risk of injury of the diver, nor shall it impair the operability of any of its component or that of a SCUBA. The BC shall be equipped with several devices permitting respectively oral and mechanical inflation, manual deflati
32、on, automatic pressure relief, drainage of entrapped water, and with a harness for securing it to the body. It can be fixed to the cylinder(s) of a SCUBA or used as the relevant body harness, can be equipped with hoses for oral inflation or for deflation, with auxiliary inflation devices, or with vi

34、sers mouth shall be smoothly finished. When tested in accordance with 5.11, the oral inflation device shall be assessed as readily accessible to the mouth and either hand in any stage of inflation of the BC. It shall be operable even when wearing protective gloves (three fingers, 61 mm, double-lined
35、). When tested in accordance with 5.5.1, the oral inflation device shall show a differential pressure drop of not more than 35 hPa. 4.2.2 Mechanical inflation device This comprises a medium pressure hose and a valve that shall be actuated subsequent to one positive manual operation such as pressing
36、a button. The coupling between the valve and the hose shall be rapidly detachable even when wearing protective gloves (three fingers, 61 mm, double-lined). The mechanical inflation device shall be subjected to a pressure test. The medium pressure hoses shall comply with the appropriate requirements
37、of EN 250. The maximum buoyancy, determined in accordance with 5.4, shall be built up within not more than 20 s at maximum flow and a rated intermediate pressure according to manufacturers instructions and in no case higher than 7 bar. Test in accordance with 5.5.2, 5.5.3 and 5.11. 4.2.3 Manual defl
38、ation device 4.2.3.1 This shall be activated subsequent to one positive manual operation, such as pressing a button or pulling a cord. It shall be operable even when wearing protective gloves (three fingers, 61 mm, double-lined). It shall either be incorporated in the oral inflation device and compl

Test in accordance with 5.11. 4.2.3.2 At the maximum manually settable position the outflow of gas shall be greater than th
40、e maximum possible inflow by either one of the mechanical inflation devices fed with at least 7 bar at a buoyancy of not more than 20 % of the maximum buoyancy. Test in accordance with 5.6.1. 4.2.3.3 After operating the manual deflation device until the outflow of gas stops, the residual buoyancy of
41、 the BC shall be not more than 10 % of the rated maximum buoyancy. Test in accordance with 5.6.2. 4.2.3.4 If the manual deflation device is operated by means of a pulling cord, it shall remain operable when tested in accordance with 5.6.3. 4.2.4 Automatic pressure relief device This shall prevent da
42、mage to the BC through overpressurisation. When tested in accordance with 5.8, the pressure inside the BC shall not exceed 50 % of its burst pressure if inflated continously with the mechanical inflator at 120 % of its rated intermediate pressure and the BC shall have a minimum burst pressure of 0,5
43、 bar above atmospherical pressure. After the last cycle defined in 5.8.2 the BC sample shall remain in a serviceable condition and the air leakage shall reduce its maximal buoyancy by not more than 20 N during a time of 1 h5 min. 4.2.5 Means for drainage of entrapped water When tested in accordance
44、with 5.9, the weight of entrapped water shall be less than 2 % of the maximum buoyancy of the BC. 4.2.6 Harness This feature, which incorporates strapping or other means of attachment shall perform its function of securing the BC to the body taking into account different body sizes. The means of att
45、achment shall not interfere with the removal of the users ballast weights when the BC is donned in accordance with the manufacturers instructions. Test in accordance with 5.11. 4.3 Optional features 4.3.1 Influence on mandatory features If BCs are equipped with optional features, these shall be asse
46、ssed as not compromising the effectiveness of the mandatory features during the practical performance test in accordance with 5.11. 4.3.2 Fixing of the SCUBA If the BC is fixed to the cylinder(s) of a SCUBA, it shall not become loose, in or out of water, when tested in accordance with 5.7 and 5.11.
