3 Foreword This document (EN 14225-4:2005) has been prepared by Technical Committee CEN/TC 162 “Protective clothing including hand and arm protection and lifejackets”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2005, and conflicting national standards shall be withdrawn at the latest by November 2005. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 89/686/EEC. This standard for one atmosphere diving suits is Part 4 of a series. The other parts are: • Diving Suits – Part 1: Wet suits − Requirements and test methods • Diving Suits – Part 2: Dry suits − Requirements and test methods
• Diving Suits – Part 3: Actively heated or cooled suit (Systems) − Requirements and test methods

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 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 environmental 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 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.

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 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 the 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 of controls and displays When a suit is tested in accordance with 5.6, the diver’s 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 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 difficulty. 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 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 Safety 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.
EN 14225-4:2005 (E)
7 4.4.2 Carbon dioxide level When tested in accordance with 5.5.1 and 5.6 the carbon dioxide (CO2) level in the atmosphere within the suit shall be less than 0,5 % for maximum time of use, as specified by the manufacturer. NOTE
