1、Designation:F262314Standard Specification forPolyethylene of Raised Temperature(PE-RT)SDR 9 Tubing1This standard is issued under the fixed designation F2623;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A
2、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 establishes requirements for polyeth-ylene of raised temperature(PE-RT)SDR 9 tubing that isoutside diameter controlled,
3、and pressure rated for water at73F(23C),140F(60C)and 180F(82.2C).Included arerequirements for material,workmanship,dimensions andtolerances,product tests,and markings for PE-RT tubing.1.2 The text of this specification references notes,footnotes,and appendixes which provide explanatory material.Thes
4、enotes and footnotes(excluding those in tables and figures)shallnot be considered as requirements of the specification.1.3 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 onl
5、yand are not considered standard.1.4 The tubing produced under this specification shall bepermitted for use in general fluid transport,including hydronicsand irrigations systems.1.5 The following safety hazards caveat pertains only to thetest methods portion,Section 7,of this specification.Thisstand
