1、Designation: F 1986 01 (Reapproved 2006)An American National StandardStandard Specification forMultilayer Pipe Type 2, Compression Fittings, andCompression Joints for Hot and Cold Drinking-WaterSystems1This standard is issued under the fixed designation F 1986; the number immediately following the d
2、esignation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers
3、requirements for multilayerpipe type 2 and compression fittings for hot and cold drinking-water systems, with a maximum pressure rating of 1000 kPa(145 psi) at 82C (180F).NOTE 1Multilayer Pipe Type 2Construction-based pressure ratedpipe comprising more than one layer in which at least 60 % of the wa
4、llthickness is polymeric material.1.2 Multilayer pipe type 2 is produced using a butt-weldedaluminum pipe as a core, with an extruded inside layer ofcrosslinked polyethylene (PEX). An adhesive layer is used tobond the inside layer to the wall of the aluminum pipe. Anouter layer of polyethylene (PE)
5、and an adhesive layer areextruded to the outer wall of the aluminum pipe.1.3 Multilayer pipe type 2 is produced in configurations 1and 2, as referenced in Fig. 1.1.4 This specification includes compression fittings, whichare referenced in Fig. 2 .1.5 Specifications for thread or solder adapters for
6、use withpipe and fittings meeting the requirements of this specificationare given in Annex A1 and Annex A2.1.6 The following precautionary caveat pertains only to thetest method portion of this specification: This standard doesnot purport to address all of the safety concerns, if any,associated with
7、 its use. It is the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.1.7 The values stated in either SI units or in inch-poundunits are to be regarded separately as standard. The value
8、sstated in each system may not be exact equivalents; therefore,each system shall be used independently of the other. Combin-ing values from the two systems may result in nonconformancewith the standard.2. Referenced Documents2.1 ASTM Standards:2B 283 Specification for Copper and Copper-Alloy Die For
