NFPA 13 (2013) Section 6.1.1.2 "Unless the requirements of 6.1.1.3, 6.1.1.4, or 6.1.1.5 are met, all materials and devices essential to successful system operation shall be listed." Section 6.1.1.3.1, "Nonmetallic pipe and fittings included in Table 6.3.1.1 and Table 6.4.1 shall be listed." Since HDPE is not listed in Table 6.3.1.1 or 6.4.1, it appears to me that you must then rely on the listing in order to use it. Section 6.3.7* states, "Nonmetallic Pipe. Nonmetallic pipe in accordance with Table 6.3.1.1 shall be investigated for suitability in automatic sprinkler installations and listed for this service." Section 6.3.7.1 states, "Listed nonmetallic pipe shall be installed in accordance with its listing limitations, including installation instructions."
NFPA 24 (2013) Section 10.1.1* states, "Listing. Piping shall be listed for fire protection service or shall comply with the standards in Table 10.1.1." HDPE is not listed for above ground installation. If code states to install in accordance with its listing, I don't see how it can be installed above grade and called compliant.

This sounds like the proverbial "slippery slope". Just my thoughts...
