1、Designation: F1733 07F1733 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
2、oforiginal 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 Scope*1.1 This specification covers polyamide (PA) butt fusi
3、on fittings for 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 regarded as standard. The values given in parentheses are mathe
4、maticalconversions to SI units that are provided for information only and are not considered standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety and he
5、alth practices and determine the applicability of regulatorylimitations prior to use.2. 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 j
6、urisdictional 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 standards body tomandatory annexes. The next ma
7、jor change occurred late in 2009 at which time all 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 tho
8、se materials that were removed from D2513 including 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 r
9、eferences D2513-99 which makes for potential confusion. 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
10、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 bedual references, both D251399 and F2945 for PA11, as see
11、n in this standard. At which time Part 192 references F2945, the PA11 gas piping standard,all references to D2513 and this note will be removed from these standards.D1598 Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal PressureD1599 Test Method for Resistance to Short-Time Hy
