21、 Switzerland and United Kingdom. EN 14225-2:2005 (E) 4 Introduction This document for dry diving suits has been prepared to meet the needs of persons engaged in underwater activities where the user is breathing underwater, and where thermal comfort and required thermal protection is higher than that

22、 provided by a wet suit. A dry suit is also designed to enable the wearers to maintain their buoyancy and to adjust the gas volume in the suit according to their requirements. A dry suit may be comprised of one or more pieces. Dry suits may be used in conjunction with a range of accessories includin

23、g passive and active undergarments, gloves, a hood and other head protection equipment. The conformity of a dry suit to this document does not imply that it is suitable for all circumstances, nor does the standard make detailed provisions for all the special uses for which dry suits may be utilised.

24、 A dry suit manufactured for special purposes may also: a) provide or enable thermal insulation; b) provide special protection. The level of protection and performance offered by a dry suit may be altered by a number of factors, including the water temperature, the depth of the dive, the divers work

25、 rate and behaviour, and the manner in which the suit has been maintained. The adequacy of the protection provided by a dry suit also depends upon the individual divers level of cold tolerance. The degree of thermal protection offered by a dry suit is especially problematic. Appropriate material and

26、 manikin tests are being developed and refined, but at best they will only be able to provide broad indications of the likely protection provided by a particular suit to an individual diver. EN 14225-2:2005 (E) 5 1 Scope This document specifies the construction and performance, of dry suits for wear

27、 by divers for underwater activities where the user is 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 doc
