1、Designation: F1733 13 An American National StandardStandard Specification forButt Heat Fusion Polyamide(PA) Plastic Fitting forPolyamide(PA) Plastic Pipe and Tubing1This standard is issued under the fixed designation F1733; the number immediately following the designation indicates the year oforigin

2、al adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers polyamide (PA) butt fusionfittings for

3、 use with polyamide pipe (IPS and ISO) and tubing(CTS). Included are requirements for materials, workmanship,dimensions, marking, sustained pressure, and burst pressure.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversion

4、s to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and

5、 determine the applica-bility of regulatory limitations prior to use.2. Referenced Documents2.1 ASTM Standards:2NOTE 1For over 40 years D2513 was the singular US CFR Title 49Part 192 referenced Standard Specification codifying the installation anduse of thermoplastic gas piping in jurisdictional ins

6、tallations. 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 by moving material-specific requirements from thestandards body to mandatory annexes. The next major change occurre

7、dlate 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-only gaspiping standard. This recent change required that new standards bedeveloped for those materials that wer

8、e 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 complying with D2513 and D2513 no longer hasthe A5 polyamide annex and Part 192 still references D2513-99 whic

9、hmakes 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 Part 192 is revised toreference the new PA11 specification, F2945, PA11 has to fall back tociting the US Code

10、 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 removedfrom D2513, there will be dual references, both D251399 and F2945 forPA11, as seen in this standard. At which

11、 time Part 192 references F2945,the PA11 gas piping standard, all references to D2513 and this note willbe removed from these standards.D1598 Test Method for Time-to-Failure of Plastic PipeUnder Constant Internal PressureD1599 Test Method for Resistance to Short-Time HydraulicPressure of Plastic Pip
