Does anyone have any specs on temp ranges other than the ANSI 60-100*F range? Is it acceptable to JUMP (temp change occurs within seconds) between 60 & 100 4 times over 2 minutes? Or, does anyone read the appendix B6 statement about the temps being conducive to a 15 minute flush period along with the amount of discomfort this type of sudden change would give to indicate that this is not acceptable? Are you required to tag a unit out of service if it goes out of this range or is it ok to just take the average temp of the water over the test period? If unacceptable, what range would be more acceptable and over what period?
When you are watching one thing and discover a new thing-.gotta love science! We have WAY too many eyewashes in our labs and the more of something you add, the more likely you are to find a problem.
