This specification establishes the materials and performance requirements for flexible, pre-insulated piping intended for hot and chilled water applications. Piping system may include one or more carrier pipes within a common outer jacket and shall be supplied in coil form. Carrier-pipe, thermal-insulation, and protective-jacket material shall be continuous and uniform throughout the coil while connections and joints in the carrier pipe and the protective jacket shall not be allowed within the coil. The pipe assembly shall be subjected to end seal and bending force tests for water infiltration inspection and to ensure the flexibility of the piping system, respectively.

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 flexible, pre-insulated piping commonly used to convey hot and cold fluids.

1.2 This specification establishes materials and performance requirements for flexible, pre-insulated piping intended for hot and chilled water applications.

1.3 Piping systems may include one or more carrier pipes within a common outer jacket.

1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered part of this standard.

1.5 Units—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.

1.6 The following safety hazards caveat pertains 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.
