3、quirements 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 wall

4、thickness 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) an

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
