9、t 192 referenced Standard Specification codifying the installation anduse of thermoplastic gas piping in jurisdictional installations.Initially allmaterials(PE,PVC,ABS,CAB)were contained within the body of thestandard D2513.In later years D2513 was completely reformatted to makeit more user friendly
10、 by moving material-specific requirements from thestandards body to mandatory annexes.The next major change occurredlate in 2009 at which time all thermoplastic materials,exceptpolyethylene,were removed from D2513 changing its Title and Scopefrom a thermoplastic gas piping standard to a polyethylene
11、-only gaspiping standard.This recent change required that new standards bedeveloped for those materials that were removed from D2513 includingPA11.This causes problems for PA11 piping because it has beenreferenced and permitted for jurisdictional use and installation under USCFR Title 49 Part 192 as
12、 complying with D2513 and D2513 no longer hasthe A5 polyamide annex and Part 192 still references D2513-99 whichmakes for potential confusion.This puts PA11 gas piping standards intosomewhat of a limbo since D2513 is now a PE-only specification isreferenced in all of these standards.Therefore until
13、Part 192 is revised toreference the new PA11 specification,F2945,PA11 has to fall back tociting the US Code referenced 1999 edition of D2513 in related standardsuch as this one.Until CFR Title 49 Part 192 references the newlydeveloped thermoplastic gas piping standards for those materials removedfro
