1.1?This specification covers polyethylene (PE) plastic tubing in outside diameters and SDRs that are pressure rated for water. Included are requirements for PE compounds, and requirements and test methods for PE plastic tubing workmanship, dimensions, elevated temperature sustained pressure, burst pressure and marking. Note 1:?Refer to specification AWWA C901 and PPI Technical
Note 49 (TN-49) for further information on pipe suitability for
potable water end use applications. Oxidative Resistance
Classification (CC# rating) information is available from NSF
International.
1.2?The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes shall not be considered as requirements of the specification. Notes and footnotes in tables and figures, and Supplementary Requirements are requirements of the specification. 1.3?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Note 2:?Joining PE plastic tubing with fittings that require
flaring the tubing is not recommended because Practice D3140, the technique used to make the
flare has been withdrawn (discontinued).
1.4?The following safety hazards caveat pertains only to the test methods portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
