31、he gas industry terminology used in this specification is in accordance with ANSI B31.8 or OPS 49 CFR Part 192, unlessotherwise indicated.3.3 The term pipe used herein refers to both pipe and tubing unless specifically stated otherwise.3.4 re-rounding equipmentequipment used to reform the pipe and p
32、ermanently reduce ovality to 5 % or less.3.5 rounding equipmentequipment, devices, clamps, and so forth, used to temporarily hold the pipe round whileout-of-roundness measurements are made, or a joining procedure (heat fusion, electrofusion, or mechanical) is performed.3.6 pipe material designated c
33、odethe pipe material designation code shall consist of the abbreviation for the type of plastic(PE) followed by Arabic numerals which describe the short term properties in accordance with applicable Specification D3350,the hydrostatic design stress for water at 73.4F (23C) in units of 100 psi with a
34、ny decimal figures dropped. Where the hydrostaticdesign stress code contains less than two figures, a zero is used before the number. Thus, a complete material designation codeshall consist of PE and four figures for PE materials. For example, PE2708 is a grade PE27 polyethylene with an 800psi desig
35、nstress for water at 73.4F (23C). The hydrostatic design stresses for gas are not used in this designation code.3.7 dimension ratio (DR)the ratio of pipe diameter to wall thickness. It is calculated by dividing the specified outside diameterof the pipe, in inches (mm), by the minimum specified wall
36、thickness, in inches (mm). The standard dimension ratio (SDR) is acommon numbering system which is derived from the ANSI preferred number series R 10.3.8 toe-ina small reduction of the outside diameter at the cut end of a length of thermoplastic pipe.4. Materials4.1 GeneralThe PE used to make pipe a
37、nd fittings shall be PE or reworked PE (see 4.2 and 4.4) and shall have a Plastics PipeInstitute (PPI) long-term hydrostatic design stress and hydrostatic design basis rating.4.2 Rework MaterialClean rework material of the same commercial designation, generated from the manufacturers own pipeand fit
38、ting production shall not be used unless the pipe and fitting produced meet all the requirements of this specification. Theuse of these rework materials shall be governed by the requirements of 4.3 and PPI TN-30/2006. In pipe, rework materials shallbe limited to a maximum of 30 % by weight.NOTE 1The
39、 requirements for rework materials herein are intended to incorporate prudent specifications to ensure that the potential for contaminationin gas piping products, that meet this specification, is reduced to the extent possible. It is imperative to emphasize that rework materials have not beenidentif
40、ied as the cause of any field failures. The requirements for rework materials were developed by the consensus of interested parties including productmanufacturers, gas utility companies, and regulatory agencies.4.3 DocumentationA documentation system to allow for traceability of raw materials includ
41、ing percentage and materialclassification (or designation, if applicable) of rework materials used in the manufacture of the pipe product meeting therequirements of this specification shall exist and be supplied to the purchaser, if requested.4.4 ClassificationPolyethylene materials suitable for use
42、 in the manufacture of pipe and fittings under this specification shallmeet Table 1 requirements for the applicable pipe material designation code.NOTE 2References and material descriptions for PE 2306, PE 2406, PE 2606, PE 3306, PE 3406, PE 3408, PE 3608, PE 3710, and PE 4608 havebeen removed from
43、D2513. Elimination of these materials does not affect the pipelines that are in service. They can still be used for gas distribution. Themain reason for removing these materials from this standard is to reflect the current state of the art in PE gas distribution piping.TABLE 1 Polyethylene Compound
