2.1 ASTM Standards:
NOTE 1—For over 40 years D2513 was the singular US CFR Title 49 Part 192 referenced Standard Specification codifying the installation and use of
thermoplastic gas piping in jurisdictional installations. Initially all materials (PE, PVC, ABS, CAB) were contained within the body of the standard D2513.
In later years D2513 was completely reformatted to make it more user friendly by moving material-specific requirements from the standard’s body to
mandatory annexes. The next major change occurred late in 2009 at which time all thermoplastic materials, except polyethylene, were removed from
D2513 changing its Title and Scope from a thermoplastic gas piping standard to a polyethylene-only gas piping standard. This recent change required
that new standards be developed for those materials that were removed from D2513 including PA11. This causes problems for PA11 piping because it
has been referenced and permitted for jurisdictional use and installation under US CFR Title 49 Part 192 as complying with D2513 and D2513 no longer
has the A5 polyamide annex and Part 192 still references D2513-99 which makes for potential confusion. This puts PA11 gas piping standards into
somewhat of a limbo since D2513 is now a PE-only specification is referenced in all of these standards. Therefore until Part 192 is revised to reference
the new PA11 specification, F2945, PA11 has to fall back to citing the US Code referenced 1999 edition of D2513 in related standard such as this one.
Until CFR Title 49 Part 192 references the newly developed thermoplastic gas piping standards for those materials removed from D2513, there will be
