SORRY FOR THE PREVIOUS SENDING. I HIT THE WRONG KEY IN ERROR. I'LL TRY TO BE MORE CAREFUL ON THIS ONE.......
In my previous life and association with FM Global, a "spring check" operation is done on a MONTHLY basis for ALL NORMALLY OPEN PIVs. The procedure you have described in for an annual turn down of normally open PIVs. The monthly spring check would consist of all the operations you have indicated, EXCEPT for having the valve going through its full range of operation. We were required by FM Global to do this on a monthly basis, and document the operations for their inspec-tion reviews. Unless dire situations existed, were never allowed to deviate from this. Hope this helps.
