1、Designation: F1970 05 F1970 12 An American National StandardStandard Specification forSpecial Engineered Fittings, Appurtenances or Valves foruse in Poly (Vinyl Chloride) (PVC) or Chlorinated Poly (VinylChloride) (CPVC) Systems1This standard is issued under the fixed designation F1970; the number im
2、mediately following the designation 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. Scope Scope
3、*1.1 This specification covers fittings, appurtenances and valves which are to be used with pipe and tubing complying withSpecifications D1785, D2241, D2846/D2846M, F441/F441M or F442/F442M, or other piping as specified by the fittingsmanufacturer. These products, such as unions, flanges or valves,
4、are not included in the scope of existing ASTM specifications.This specification includes minimum requirements for testing, materials, dimensions, workmanship, marking, and in-plant qualitycontrol.1.2 Fittings or appurtenances covered by this specification are generally either molded, fabricated, or
5、 assembled from moldedor machined components. The materials used in components include rigid thermoplastics, thermoplastic elastomers, elastomerics,and metals. The body or main portion of the fitting, appurtenance or valve is typically PVC, CPVC, PE or PA (nylon). All productscovered by this standar
6、d are intended to be used in PVC or CPVC plastic piping systems, or as a transition from these to metalsystems.1.3 The application of these products to gas service is beyond the scope of this specification.1.4 The products covered by this specification are intended for use with the distribution of p
7、ressurized liquids only, which arechemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems withcompressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult withspecific product/com
8、ponent manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 1Warning: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety whichpresent serious safety hazards should a system fail for any reason.1.5
9、Fittings which rely on heat fusion welding for connection to the piping system are outside the scope of this specification.1.6 Check valves (including foot valves) covered by this specification shall not be considered backflow prevention devices andshall not be used for the protection of a potable w
10、ater supply. For definitions and requirements of backflow prevention devices,consult model plumbing codes and ASSE.21.7 Due to the complex and installation-specific concerns surrounding chemical resistance and corrosion, this specification doesnot address the compatibility of the products with all p
11、ossible end-use environments. Additional testing specific to the end-useenvironment is recommended if the system is conveying liquids other than potable water.1.8 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are given forinformation only
12、.1.9 The following safety caveat applies only to the test methods and in-plant quality control portions, section of thisspecification:This standard does not purport to address all of the safety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establi
