Testing is in accorda

34、nce with 5.2 and 5.13. If the BC has more than one bladder, then each bladder, together with the associated inflation and deflation device, shall comply with the requirements of this standard. 4.2 Mandatory features 4.2.1 Oral inflation device Parts of the device that come into contact with the user

35、s mouth shall be free of sharp edges and corners. When tested in accordance with 5.13, 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, (6 1) mm

36、, double-lined). The oral inflation device shall allow the BC to be easily inflated by mouth when tested in accordance with 5.13. The oral inflation device shall withstand a pulling force of 150 N for (10 1) s without damage and remain functional. Testing is in accordance with 5.10. 4.2.2 Compressed

37、 gas inflation device This comprises a medium pressure hose and a valve that shall be actuated subsequent to one positive, manual operation such as pressing a button, or by an automatic control system. Gas supply shall be capable of simple isolation or able to be disconnected between the hose and th

38、e inflation device by a quick connect coupling. If a quick connection coupling is fitted, the preferred configuration for the male part of the inflation device is as shown in Figure 1, where only the relevant dimensions are specified. If the configuration of the connection used is different from the

39、 preferred one, it shall not be possible to connect the female connection to the preferred male connector. It shall be possible to isolate or disconnect the gas supply with either hand when wearing protective gloves (three fingers, 6 mm 1 mm, double-lined). Testing is in accordance with 5.13. BS EN

The inflation device shall withstand a medium pressure of at le

41、ast 30 bar for 60 s. Testing is in accordance with 5.6.2. The medium pressure hoses assembly shall comply with the appropriate requirements of EN 250. If the medium pressure hose is provided with a quick connect coupling, the hose connected to the male part of the quick connect coupling shall have a

42、 minimum air flow of 250 l/min STPD, when connected to a constant 10 bar supply. Testing is in accordance with 5.12. The maximum buoyancy, determined in accordance with 5.5, shall be built up at a rate greater than 15 N/s at a minimum medium pressure according to manufacturers instructions and in no

43、 case higher than 6 bar. Testing is in accordance with 5.6.1. 4.2.3 Deflation device 4.2.3.1 The BC shall have at least one manually operated deflation device. Testing is in accordance with 5.13. 4.2.3.2 If deflation devices are manually operated, they shall be activated by one positive manual opera

44、tion, such as pressing a button or pulling a cord. They shall be operable even when wearing protective gloves (three fingers, (6 1) mm, double-lined). At least one device shall be readily accessible at any stage of operation of the BC. Testing is in accordance with 5.13. 4.2.3.3 The flow capacity of

45、 at least one deflation device shall be greater than the maximum flow that may be achieved by any individual inflation device.
