2、original 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. Scope*1.1 This specification covers cold-expansion fittings usingmet
3、al compression-sleeves for use with cross-linked polyeth-ylene (PEX) plastic pipe in38-in.,12-in.,58-in.,34-in., 1-in.,114-in., 112-in., and 2 in. nominal diameters, whereby the PEXpipe is cold-expanded before fitting assembly. These cold-expansion fittings and metal compression-sleeves are intended
4、for use in residential and commercial, hot and cold, potablewater distribution systems, as well as sealed central heating,including under-floor heating systems, with continuous opera-tion at pressures up to and including 100 psi (690 kPa), and attemperatures up to and including 180F (82C).1.2 Includ
5、ed in this specification are the requirements formaterials, workmanship, dimensions, and markings to be usedon the fittings and compression-sleeves. Performance require-ments are as referenced in Specification F877.1.3 The values stated in inch-pound units are to be regardedas the standard. The valu
6、es given in parentheses are mathemati-cal conversions to SI units that are provided for informationonly and are not considered standard.1.4 The following precautionary caveat pertains only to thetest method portion, Section 10, of this specification. Thisstandard does not purport to address all of t
7、he safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
