2、ignation 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 () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers req
3、uirements 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 wallt
4、hickness 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) and
5、 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 use
6、 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 it
7、s 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 inch-pound unitsare to be regarded separately as standard. The values stat
8、ed ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2.
