These cold-expansion fittings and metal compression-sleeves are intend
4、edfor 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 Incl
5、uded 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 F 877.1.3 The values stated in inch-pound units are to be regardedas the standard. The v
6、alues 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 o
7、f the 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.
