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
