Introduction This document for actively heated or cooled diving suits (systems) has been prepared to meet the needs of persons engaged in underwater activities where the user is breathing underwater, and where the water temperature and exposure duration are such that the person's thermal status only can be maintained at a safe level by means of active heating or cooling. Actively heated suits and actively cooled suits are designed to reduce the risk of the diver suffering hypothermia and hyperthermia, respectively. The performance of the suit can be altered by a number of factors including any additional equipment carried by the diver. A suit may be comprised of one or more pieces.

The thermal system shall have sufficient residual capacity for a situation with failure of the heating or cooling system to allow either the diver to return to a point of safety or an alternative system to be provoked. NOTE 1 Attention is also drawn to the Low Voltage Directive 73/23/EEC (Electrical equipment designed for use within certain voltage limits). NOTE 2 In the case of chemical systems, attention is drawn to national legislation regarding occupational exposure limits. 4.8 Practical performance requirements When tested in accordance with 5.10 it shall be possible for the suit system to be donned and doffed with the assistance of no more than one person. When suits are subjected to practical performance tests in accordance with 5.10 the test divers shall be able to carry out all the procedures listed in 5.10 and shall not report a practical performance score of 5 or more (given in A.1) for more than 3 of the separate test procedures, and no score higher than 8 for any procedure. When actively heated or cooled suits are tested in accordance with 5.10, at no stage during the dive shall the test diver report a thermal comfort score of 4 or less for an actively heated suit, or 9 or higher for an actively cooled suit (see A.2). Neither shall the diver report a perceived exertion score of 5 or more at any stage during the dive (see A.3).



EN 14225-3:2005 (E) 12 When tested in accordance 5.10 the satisfactory surface condition of the suit in contact with the user shall be confirmed by showing no excessive irritation, abrasions or other skin injuries. 4.9 Optional features 4.9.1 Special protection 4.9.1.1 Protection against chemicals For suits intended to provide the user with protection against chemicals in the diving environment, the suit material and critical interfaces, e.g. seams, latex closures and slide fasteners, shall be tested in accordance with 5.11.1. The average normalized breakthrough detection time shall be a minimum of 20 min. Materials with an average normalized breakthrough detection time of 20 min to 60 min shall be deemed to have a low protection index and materials with an average normalized breakthrough detection time of more than 60 min shall be deemed to have a high protection index. The protection index, and the chemicals against which protection was shown, shall be marked on the suit [see Clause 6 item n)]. Instructions on effective methods for decontaminating the suit and measuring that decontamination has been effectively achieved shall be provided by the manufacturer. 4.9.1.2 Protection against micro-organisms For suits intended to provide the user with protection against micro-organisms e.g. infective agents in the diving environment, the suit material and critical interfaces, e.g. seams, latex closures and slide fasteners, shall have at least the performance levels Class 6 when tested as required in EN 14126:2003, 4.1.4.1 and 4.1.4.2. 4.9.2 Visibility 4.9.2.1 Colour If the suit manufacturer claims the suit to have a colour enhancing the visibility, this property shall be documented and include an area of the suit not less than 50 % of the total suit area when tested in accordance with 5.3. This enhanced visibility shall be for the relevant use environment. The colour fastness of suit material when determined in accordance with ISO 105-A02:1993 shall be resistant to rubbing (wet and dry), when tested in accordance with EN ISO 105-X12:2002 to at least step 4, and to salt water when tested in accordance with EN ISO 105-E02:1996 to at least step 4. 4.9.2.2 Retroreflective material There shall be affixed to the suit surface a total area of at least 400 cm2 of material which is retroreflective to light and which conforms to the recommendation detailed in IMO SOLAS 83:1974, Chapter III, Resolution A.658(16), Annex 2, as it may be amended.
