23、led 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 persons thermal status only can be maintained at a safe level by means of active

24、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

25、 be comprised of one or more pieces. EN 14225-3:2005 (E) 5 1 Scope This document specifies the construction and performance of actively heated suits and actively cooled suits for wear by divers for underwater activities where the user is breathing underwater. Marking, labelling, information to be pr

26、ovided at the point of sale, and instructions for use are also specified. The document applies to the actively heated or cooled suits (systems) of the two types, dry and wet. It is only required that the suit should fulfil this Part 3, not the Parts 1 or 2 unless specified. Laboratory and practical

27、performance tests are specified. 2 Normative references The following referenced documents are indispensable for the application of this document.
