However, attention is drawn to the fact that during the development of this European Standard, the UK consistently voted a

The committee would therefore draw the readers attention to the fact that current Merchant Shipping Acts and Regulations made under them, and International Maritime Organization Resolutions on submersibles should be consulted prior to applying

EN 14225-4:2005 (E) 4 Introduction This part of EN 1422
26、5 for one atmosphere diving suits (ADS) has been prepared to meet the human factors requirements of persons engaged in underwater activities where protection against environmental conditions and decompression hazards are essential. A one atmosphere suit (ADS) is designed to: a) Protect the diver fro
27、m 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 conduct work by means of articulated arms and legs. The performance of the suit system can be altered by a number of factors
28、including additional equipment. A one atmosphere suit (ADS) can be comprised of several sub-assemblies. EN 14225-4:2005 (E) 5 1 Scope This European Standard specifies the human factors performance of one atmosphere diving suits (ADS) where the diver can make use of articulated arms and legs and is a
29、ble to conduct underwater activities while breathing underwater. Marking, labelling, information to be provided at the point of sale, and instructions for use are also specified. Laboratory and practical performance tests are specified. 2 Normative references The following referenced documents are i
30、ndispensable for the application of this document. For dated references, only the edition cited applies.

34、hanical performance 4.1.1 Resistance to cleaning, disinfection and decontamination Following actual use by divers the interior of the suit shall be subjected to cleaning, disinfection against biological contamination such as bacteria, virus, fungi and other biological contaminants in accordance with
35、 5.4, 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
36、EN 340 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 t
37、he size 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. Testing in accordance with 5.5 and 5.6. 4.2.3 Field of vision and visibility o
38、f controls and displays When a suit is tested in accordance with 5.6, the divers field of vision shall be not less than 120 in the horizontal plane and not less than 90 in the vertical plane. The controls and displays inside the suit shall be so positioned that during the test in accordance with 5.6
39、 the diver can view them comfortably and clearly with normal or corrected vision. 4.2.4 Provision for urination The suit shall be provided with a system to allow the diver to urinate while inside the suit. During the test in accordance with 5.6, the diver shall be able to use this system without dif
40、ficulty. 4.3 Internal temperature and humidity When the suit is tested in accordance with 5.5 and 5.6 the mean internal temperature shall not exceed 30 C and shall not fall below 15 C in any part of the suit at any time during the test, and the relative humidity shall not exceed 60 % throughout the
41、test. The body core temperature of the diver shall not vary by more than 1 C throughout the test (5.6). The suit shall have means by which the diver can adjust the thermal properties provided by the total system to compensate for variations in his or her physical activity and heat production. 4.4 Sa
42、fety requirements 4.4.1 Oxygen level When tested in accordance with 5.5.1 and 5.6 the oxygen (O2) level in the atmosphere within the suit shall be (21 2) % for maximum time of use, as specified by the manufacturer.
