ASTM D2737-99

1.1 This specification covers polyethylene (PE) tubing pressure rated for water (see appendix). Included are criteria for classifying PE plastic tubing materials and PE plastic tubing, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, and environmental stress cracking. This specification differs from the pipe specifications in their outside diameters. Methods of marking are also given.

1.2 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

Note 1 - PE plastic tubing is often used with fittings that require flaring the tubing. The technique used to make the flare is highly important to produce leak-free joints. For further information, refer to Practice D 3140.

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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
