EN 14225-1:2005 (E) 4 Introduction This document for wet diving suits has been prep

22、ared to meet the needs of persons engaged in underwater activities where the user is breathing underwater, and where water temperature and exposure duration are such that the persons thermal requirement can be met using a wet suit. A wet suit may be comprised of one or more pieces. The conformity of

23、 a wet suit to this document does not imply that it is suitable for all circumstances nor does the document make detailed provision for all special uses for which wet suits may be utilised. The thermal protection provided by a wet suit may be affected by a number of factors including the following:

24、water temperature; divers morphology (body surface area and shape, amount of body fat, sex); divers physiology; divers rate of work and working conditions; thermal properties of the material of the wet suit. Most of these factors are individual and significantly change from diver to diver and from d

25、ive to dive. EN 14225-1:2005 (E) 5 1 Scope This document specifies the construction and performance requirements (including thermal) of wet suits for wear by divers for underwater activities where the user is breathing underwater. Marking, labelling, information to be provided at the point of sale,

26、and instructions for use are also specified. Laboratory and practical performance tests are specified. Short sleeve jackets, short-leg trousers, under and over-garments, and separate accessories such as gloves, hoods and boots are not within the scope of this document. 2 Normative references The fol
