BS EN 142251:2017EN 14225-1:2017 (E) 5 Introduction This document for wet diving suits has been prepared to meet the needs of persons engaged in underwater activities where th
32、e 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 a wet suit to this document does not imply that it is suitable for all cir
33、cumstances nor does the document make detailed provision for all special uses for which wet suits may be utilized. The thermal protection provided by a wet suit may be affected by a number of factors including the following: water temperature; divers morphology (body surface area and shape, amount o
34、f 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 dive to dive. BS EN 142251:2017EN 14225-1:2017 (E) 6 1 Scope This European S
35、tandard 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 meant to be provided at the point of sale, and instructions for use are also specified
36、. Laboratory and practical performance tests are specified. Short sleeve jackets, short-leg trousers, under- and overgarments, and separate accessories such as gloves, hoods and boots are not within the scope of this document. NOTE Suits and shorties for snorkelling including underwater activities a
37、re not covered by this standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referen
