Interesting wording in UL 1285 - "Pipe and Couplings, Polyvinyl Chloride (PVC), and Oriented Polyvinyl Chloride (PVCO) for Underground Fire Service"
1.4 Requirements for the installation and use of PVC pressure pipe and couplings are specified in the Standard for the Installation of Private Fire Service Mains and their Appurtenances, NFPA 24 or the Standard for the Installation of Sprinkler Systems, NFPA 13. So if NFPA 13 or 24 allows the stub-up and transition above slab, where is it stated that it is not? Just curious...... Craig L.

This is another RARE case where the normal process (ie follow the cut-sheet requirements via the listing) is exempted by the technical committee. Another example is the listed sprinklers required by 8.15.1.6 for concealed combustible spaces with a depth less than 36 in. The listing applies only to solid wood joist but 8.15.1.7 allows that sprinkler to be used with composite wood joists.
