Introduction
This document for wet diving suits has been prepared 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 person's 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 circumstances 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;
— diver’s morphology (body surface area and shape, amount of body fat, sex);
— diver’s physiology;
— diver’s 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.
