1、Designation:D273712aStandard Specification forPolyethylene(PE)Plastic Tubing1This standard is issued under the fixed designation D2737;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
2、indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers polyethylene(PE)plastic tub-ing in outside diamet
3、ers and SDRs that are pressure rated forwater.Included are requirements for PE compounds,andrequirements and test methods for PE plastic tubingworkmanship,dimensions,elevated temperature sustainedpressure,burst pressure and marking.1.2 The text of this specification references notes,footnotes,and ap
4、pendixes which provide explanatory material.Thesenotes and footnotes shall not be considered as requirements ofthe specification.Notes and footnotes in tables and figures,andSupplementary Requirements are requirements of the specifi-cation.1.3 The values stated in inch-pound units are to be regarded
5、as standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.NOTE1Joining PE plastic tubing with fittings that require flaring thetubing is not recommended because Practice D3140,the technique used tomake th
6、e flare has been withdrawn(discontinued).NOTE2References and PE compound descriptions for PE2305,PE2406,PE3306,PE3406,and PE3408 have been removed due tochanges in Specification D3350 and PPI TR-3.For removed designations,refer to previous editions of Specification D2737,Specification D3350,PPI TR-3
