Yo, Tommy D! In my collection, the NFPA 13 editions jump from 1958 to 1966 to 1974. The first time I see calc's are in the 1966 edition. However, that edition says that there are also editions from 1960,1961,1963,1964 and 1965. Among the many members of the committee at this time were Jack Wood (Mr. Hydraulic Calcs), Frank Fee, Jr., Wayne Ault, and Harry Marryatt. The list goes on, but wow. Wish I had more to tell. And a big thanks to Jim Melton of Nelson Fire Protection for donating that edition to the Academy's Library!
It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.
