In a previous ballot, it was brought the Task Groups attention that there are several references to cold water absorption that are not defined. There are actually two time frames to choose from a 5 hr and 24 hr submersion in cold water. This revision will clearly state that it is the 24 hr cold water absorption that is required. The proposal is consistent with other C15.02 standards.
