ASTM F2855 - 19 - Standard Specification for Chlorinated Poly(Vinyl Chloride)/Aluminum/Chlorinated Poly(Vinyl Chloride) (CPVC-AL-CPVC) Composite Pressure Tubing

ASTM F2855 - 19

Standard Specification for Chlorinated Poly(Vinyl Chloride)/Aluminum/Chlorinated Poly(Vinyl Chloride) (CPVC-AL-CPVC) Composite Pressure Tubing

Status : Current   Published : April 2019



1.1 This specification covers a Chlorinated Poly(Vinyl Chloride)/Aluminum/Chlorinated Poly(Vinyl Chloride), (CPVC AL CPVC), composite pressure tubing with a welded aluminum tube reinforcement between the inner and outer layers. The inner and outer CPVC layers are bonded to the aluminum tube by a melt adhesive. Included is a system of nomenclature for the composite tubing, the requirements and test methods for materials, the dimensions of the component layers and finished tubing, adhesion tests, hydrostatic burst and sustained pressure and thermocycling performance. Also given are the requirements and methods of marking. The components covered by this specification are intended for use in residential and commercial, hot and cold, potable water distribution systems.

Note 1:  The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.2 This specification covers only composite tubing incorporating a continuously welded aluminum tube. Tubing consisting of metallic layers not continuously welded together are outside the scope of this specification.

1.3 Specifications for internal bushings for use with composite tubing meeting the requirements of this specification are given in Annex A1.

1.4 Tubing meeting the requirements of this standard are designed to be used with fittings and solvent cements meeting the requirements of Specification D2846/D2846M when assembled in accordance with Annex A2. Warning—Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards should a system fail for any reason.

1.5 The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the tubing materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult with specific product manufacturers for their specific testing procedures prior to pneumatic testing.

1.6 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:  Suggested hydrostatic design pressures and pressure ratings for tubing are listed in Appendix X1.

1.7 The following safety hazards caveat pertains only to the test method portion, Section 9. 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.

1.8  This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
