Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.e1NOTEFigure 4 was editorially revised in November 2005.

3、1. Scope1.1 This specification covers stainless steel clamps for usewith four sizes of insert fittings that comply with F 1807, andcross-linked polyethylene (PEX) plastic tubing that complieswith F 876 or F 877. These clamps are intended as an alterna-tive to the copper-alloy crimp-rings of Specific

4、ations F 1807 orF 2159 for use in 100 psi (689.5 kPa) cold- and hot-waterdistribution systems operating at temperatures up to andincluding 180F (82C). Included are requirements for mate-rials, workmanship, dimensions and marking of the stainlesssteel clamps; requirements for deforming the clamps; wh

5、ichapply to assemblies of PEX tubing and Specifications F 1807and F 2159, insert fittings secured with deformed clamps perthis specification.1.2 The values stated in inch-pound units are to be regardedas the standard. The SI values stated in parentheses areprovided for information purposes.1.3 This

6、standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
