A superscript epsilon (ε) indicatesan editorial change since the last revision orre-approval.This standard has been approved for use by agencies of theDepartment of Defense.CommentsThis standard has been approved for use by agencies of theDepartment of Defense.1. Scope1. Scope1.1 This specification covers requirements and test methodsfor material (see Appendix X1) dimensions and tolerances,hydrostatic burst strength, chemical resistance, and impactresistance of plastic pipe, tubing, and fittings for use in fuel gasmains and services for direct burial and reliner applications. Theannexes provide specific requirements and test methods for eachof the materials currently approved. If and when additionalmaterials are available, specific annex requirements will beadded. The pipe and fittings covered by this specification areintended for use in the distribution of natural gas. Requirementsfor the qualifying of polyethylene systems for use with liquefiedpetroleum gas are covered in Annex A1.1.1.1 This specification does not cover threaded pipe. Designconsiderations are discussed in Appendix X2. In-plant qualitycontrol programs are specified in Annex A3 and Annex A4.1.2 The text of this specification references notes, footnotes,and appendixes which provide explanatory material. These notesand footnotes (excluding those in tables and figures) shall not beconsidered as requirements of the specification.1.1 This specification covers requirements and test methodsfor material dimensions and tolerances,hydrostatic burststrength, chemical resistance, and rapid crack resistance ofpolyethylene pipe, tubing, and fittings for use in fuel gas mainsand services for direct burial and reliner applications.

Materials4. Materials4.1 General—The plastic used to make pipe and fittings shallbe virgin plastic or reworked plastic (see 4.2) as specified in theAnnexes and shall have a Plastics Pipe Institute (PPI) long-termhydrostatic design stress and hydrostatic design basis rating.4.2 Rework Material—Clean rework material of the samecommercial designation, generated from the manufacturer's ownpipe and fitting production shall not be used unless the pipe andfitting produced meet all the requirements of this specification.4.1 General—The PE used to make pipe and fittings shallbe PE or reworked PE (see 4.2 and 4.4) and shall have a PlasticsPipe Institute (PPI) long-term hydrostatic design stress andhydrostatic design basis rating.4.2 Rework Material—Clean rework material of the samecommercial designation, generated from the manufacturer's ownpipe and fitting production shall not be used unless the pipe andfittingproduced meet all the requirements of thisspecification. The use of these rework materials shall begoverned by the requirements of 4.3 and PPI TN-30/2006 Inpipe, rework materials shall be limited to a maximum of 30 %by weight.NOTE 1—References and material descriptions for ABS,CAB, PB, PE2306, PE3306 and PE3406 have been removed fromD 2513. Elimination of these materials does not affect thepipelines that are in service. They can still be used for gasdistribution. The main reason for removing these materials fromPage 3 of 61NOTE 1—The requirements for rework materials herein areastmfiles/comparison, D2513 99 vs. 09a, RWC, 042811CommentsChanged “standard thermoplasticmaterial” to “pipe material” – due tofocus on PE only.Eliminated example reference to PVC andPA-these materials no longer in thisspecification.Changed “applicable ASTM standards” toSpecification D3350-PE only so thespecific standard is referenced.Eliminated “two or three letters” – PEonly so this option is not needed.Changed reference material and stressfrom “PE 2406” and “ 630 psi” to “PE2708” and “ 800” psi – materialdesignations and reference stresschanged to reflect new, high performancePE material.“Thermoplastic pipe” eliminated-thiscomment was redundant.4.1Only change is to reference 4.4 for the PEmaterial classification codes4.2 and Note 1Based on a extensive project byNYSEARCH (with AGA PMC and PPIparticipation), the use of rework in gaspipes was limited to a maximum of 30%.This 30% limitation represents a“strengthening” of the gas pipe standard.The project was initiated in response to aPHMSA request and was fully supportedby such.

Plastics Pipe Institute: Comparison of ASTM D-2513 Editions: ’99 vs. ‘09aUpdated June 29, 2011‘09a Edition’99 Editionthis standard is to reflect the current state of the art in gas intended to incorporate prudent specifications to ensure that thedistribution plastic piping.potential for contamination in gas piping products, that meetthis specification, is reduced to the extent possible. It isimperative to emphasize that rework materials have not beenidentified as the cause of any field failures. The requirementsfor rework materials were developed by the consensus ofinterested parties including product manufacturers, gas utilitycompanies, and regulatory agencies
