Other labs can also perform this service, but I do not have any information on them. Upon acceptance by the standards council, NFPA 750 should be in print and available this year. This standard, like NFPA 13, is intended to only indicate HOW not WHEN to install a mist system. Unlike NFPA 13, it is a brand new standard and, naturally, is not as detailed. Thus, guidance on installation relies heavily on the limitations of the UL Listing and on manufacturer's recommendations.
