Introduction
This document for actively heated or cooled diving suits systems and components 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 person's thermal status only
can be maintained at a safe level by means of active 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 be comprised of one or more pieces.
