Designation:F214513Standard Specification forPolyamide 11(PA 11)and Polyamide 12(PA12)MechanicalFittings for Use on Outside Diameter Controlled Polyamide11 and Polyamide 12 Pipe and Tubing1This standard is issued under the fixed designation F2145;the number immediately following the designation indicates the year 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*1.1 This specification describes requirements and test meth-ods for the qualification of Polyamide 11(PA 11)bodiedmechanical fittings for use with outside diameter controlledPolyamide 11(PA 11),nominal 2 pipe size(IPS),and smallercomplying with Specification D2513.Additionally,the require-ments and test methods for the qualification of Polyamide 12(PA12)bodied mechanical fittings for use with outside diam-eter controlled Polyamide 11(PA11)nominal 2 in pipe size(IPS)and smaller complying with Specification D2513 andoutside diameter controlled Polyamide 12(PA12)nominal 2 inpipe size(IPS)and smaller complying with SpecificationF2785.In addition,it specifies general requirements of thematerial from which these fittings are made.1.2 The test methods described in this specification are notintended to be used as routine quality tests.1.3 This specification covers the types of mechanical fittingscovered in 3.2.1.1.4 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 The following safety hazards caveat pertains only to thetest methods portion,Section 7,of this specification.Thisstandard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory require-ments prior to use.1.6 The text of this specification references notes andfootnotes,which provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of this specification.2.Referenced Documents2.1 ASTM Standards:2NOTE1For 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 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 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-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 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 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 removedfrom D2513,there will be dual references,both D251399 and F2945 forPA11,as seen in this standard.At which time Part 192 references F2945,the PA11 gas piping standard,all references to D2513 and this note willbe removed from these standards.D638 Test Method for Tensile Properties of PlasticsD1598 Test Method for Time-to-Failure of Plastic PipeUnder Constant Internal PressureD1600 Terminology forAbbreviated Terms Relating to Plas-ticsD2513 Specification for Thermoplastic Gas Pressure Pipe,Tubing,and FittingsD2837 Test Method for Obtaining Hydrostatic Design Basisfor Thermoplastic Pipe Materials or Pressure Design Basisfor Thermoplastic Pipe ProductsF412 Terminology Relating to Plastic Piping Systems1This specification is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.60 on Gas.Current edition approved May 1,2013.Published May 2013.Originallyapproved in 2001.Last previous edition approved in 2009 as F214509.DOI:10.1520/F2145-13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Custom
