Re: Define a Chlorine Solution.

Sorry I don't have access to the NSF or AWWA standards manuals; that would 
have been the definitive source for your question.  However, I did find a 
plumbing material resistance chart at

Hypalon should work fine with hypochlorite solutions, but it's iffy with 
straight chlorine.

Bob Peeples adds:

The specification referring to "clorine solutions" is probably 
referring to the hypochlorite (bleach) solutions used most often to introduce 
chlorine into water. "Straight chlorine" (chlorine gas) is dangerous and costly 
to manage properly. Only very large scale operations use chlorine gas. Most 
likely, the intent of the specification was to use teflon where hypochlorite 
solutions are contacted. This is probably not the answer that you were hoping 
for, and hypalon may have a reasonably long life expectancy, but that doesn't 
sound like what the specification calls for.
