    Abstract

    This specification establishes the requirements for 0.070 in. wall thickness crosslinked polyethylene (PEX) tubing that is outside diameter controlled, and intended for non-potable radiant heating applications for pressures up to 75 psig. It covers requirements and test methods for material, workmanship, dimensions, burst pressure, hydrostatic sustained pressure, bent-tube hydrostatic pressure, environmental stress cracking, stabilizer functionality, excessive temperature and degree of crosslinking, as well as requirements for tubing markings.

    This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

    1. Scope

    1.1 This specification covers 0.070 in. wall thickness crosslinked polyethylene (PEX) tubing that is outside diameter controlled, and intended for non-potable radiant heating applications for pressures up to 75 psig in sizes 5/8 NTS (nominal tubing size) and 7/8 NTS. This specification also includes fittings that are specifically designed for this 0.070 in.-wall PEX tubing. Only 75-psig relief valves shall be used with this tubing. Included in this specification are requirements and test methods for material, workmanship, dimensions, burst pressure, hydrostatic sustained pressure, environmental stress cracking, stabilizer functionality, bent-tube hydrostatic pressure, excessive temperature and degree of crosslinking. Requirements for tubing markings are also given. This tubing does not have an oxygen diffusion barrier layer and shall not be used in systems that require a barrier layer. This tubing is not intended for field bending at temperatures above 120ºF (49ºC).

    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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

    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.
