Roland, It is nice that the NFPA 13 committee has modified, however the lawyers will have a field day hanging the contractor out to dry since the contractor will be saying, in front of a jury, "that he did not follow the pipe manufacturer's UL listing because NFPA 13 (a consensus minimum level standard) allowed him to not follow the UL listing" I do not think that NFPA 13 will get in front of the jury to say the NFPA 13 Committee will accept the liability.

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.
