However, attention is drawn to the fa

The committee would therefore draw the readers attention to the fact that current Merchant Shipping Acts and Regulations made under them, and International Ma

27、Wang Bin, na, Tue May 09 02:51:11 BST 2006, Uncontrolled Copy, (c) BSIEN 14225-4:2005 (E) 4 Introduction This part of EN 14225 for one atmosphere diving suits (ADS) has been prepared to meet the human factors requirements of persons engaged in underwater activities where protection against environme

28、ntal conditions and decompression hazards are essential. A one atmosphere suit (ADS) is designed to: a) Protect the diver from the underwater pressure and thus remove the need for lengthy decompression procedures; b) Reduce the risk of hypothermia or hyperthermia; c) To enable the diver to move and

29、conduct work by means of articulated arms and legs. The performance of the suit system can be altered by a number of factors including additional equipment. A one atmosphere suit (ADS) can be comprised of several sub-assemblies. Licensed Copy: Wang Bin, na, Tue May 09 02:51:11 BST 2006, Uncontrolled

37、 and shall then be controlled with regards to efficiency of the recommended method of disinfection. Visual inspection shall reveal no indication of damage to the suit system as a result of the disinfection. 4.2 Construction 4.2.1 Sizing The manufacturer shall use the sizing system specified in EN 34

38、0 if applicable or another sizing system. If the manufacturer uses a sizing system other than that specified in EN 340, the manufacturer shall state what body dimensions the suit is intended for in its different body compartments. When the suit is donned by a test diver in accordance with 5.6 the si

39、ze of the suit shall correspond to the size specified by the manufacturer. 4.2.2 Internal pressure control The internal pressure of the suit should remain between 900 mbar and 1200 mbar through the foreseen use time.
