Referenced Documents2.1 ASTM Standards:2NOTE 1For over 40 years D2513 was the singular US CFR Title 49 Part 192 referenced Standard Specification codifying the installation and use ofthermoplastic gas piping in jurisdictional installations. Initially all mater
10、ials (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 standards body tomandatory annexes. The next major change occurred late in 2009 at which time a
11、ll thermoplastic materials, except polyethylene, were removed fromD2513 changing its Title and Scope from a thermoplastic gas piping standard to a polyethylene-only gas piping standard. This recent change requiredthat new standards be developed for those materials that were removed from D2513 includ
12、ing PA11. This causes problems for PA11 piping because ithas been referenced and permitted for jurisdictional use and installation under US CFR Title 49 Part 192 as complying with D2513 and D2513 no longerhas the A5 polyamide annex and Part 192 still references D2513-99 which makes for potential con
13、fusion. This puts PA11 gas piping standards intosomewhat 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 referencethe new PA11 specification, F2945, PA11 has to fall back to citing the US Code referenced 1999 editi
14、on 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 bedual references, both D251399 and F2945 for PA11, as seen in this standard. At which time Part 192 refer
15、ences F2945, the PA11 gas piping standard,all references to D2513 and this note will be removed from these standards.D638 Test Method for Tensile Properties of PlasticsD1598 Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal PressureD1600 Terminology for Abbreviated Terms Relati
