Designation:F1970121Standard 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 immediately 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.1NOTESection 2 was editorially updated in August 2013.1.Scope*1.1 This specification covers fittings,appurtenances andvalves which are to be used with pipe and tubing complyingwith Specifications D1785,D2241,D2846/D2846M,F441/F441M or F442/F442M,or other piping as specified by thefittings manufacturer.These products,such as unions,flangesor valves,are not included in the scope of existing ASTMspecifications.This specification includes minimum require-ments for testing,materials,dimensions,workmanship,marking,and in-plant quality control.1.2 Fittings or appurtenances covered by this specificationare generally either molded,fabricated,or assembled frommolded or machined components.The materials used incomponents include rigid thermoplastics,thermoplasticelastomers,elastomerics,and metals.The body or main portionof the fitting,appurtenance or valve is typically PVC,CPVC,PE or PA(nylon).All products covered by this standard areintended to be used in PVC or CPVC plastic piping systems,oras a transition from these to metal systems.1.3 The application of these products to gas service isbeyond the scope of this specification.1.4 The products covered by this specification are intendedfor use with the distribution of pressurized liquids only,whichare chemically compatible with the piping materials.Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases somemanufacturers do not allow pneumatic testing of their products.Consult with specific product/component manufacturers fortheir specific testing procedures prior to pneumatic testing.NOTE1Warning:Pressurized(compressed)air or other compressedgases contain large amounts of stored energy which present serious safetywhich present serious safety hazards should a system fail for any reason.1.5 Fittings which rely on heat fusion welding for connec-tion to the piping system are outside the scope of thisspecification.1.6 Check valves(including foot valves)covered by thisspecification shall not be considered backflow preventiondevices and shall not be used for the protection of a potablewater supply.For definitions and requirements of backflowprevention devices,consult model plumbing codes andASSE.21.7 Due to the complex and installation-specific concernssurrounding chemical resistance and corrosion,this specifica-tion does not address the compatibility of the products with allpossible end-use environments.Additional testing specific tothe end-use environment is recommended if the system isconveying liquids other than potable water.1.8 The values stated in inch-pound units are to be regardedas the standard.The SI units given in parentheses are given forinformation only.1.9 The following safety caveat applies only to the testmethods and in-plant quality control portions,section of thisspecification:This standard does not purport to address all ofthe safety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:3D1598 Test Method for Time-to-Failure of Plastic PipeUnder Constant Internal PressureD1599 Test Method for Resistance to Short-Time HydraulicPressure of Plastic Pipe,Tubing,and Fittings1This specification is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.10Current edition approved Nov.1,2012.Published December 2012.Originallyapproved in 1999.Last previous edition approved in 2005 as F197005.DOI:10.1520/F1970-12.2American Society of Sanitary Engineering,28901 Clemens Rd.,Suite 100,Westlake,OH 44145.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 D1600 Terminology forAbbreviated Terms Relating to Plas-ticsD1784 Specification for Rigid Poly(Vinyl Chloride)(PVC)Compounds and Chlorinated Poly(Vinyl Chloride)(CPVC)CompoundsD1785 Specification for Poly(Vinyl Chloride)(PVC)PlasticPipe,Schedules 40,80,and 120D1898 Practice for Sampling of Plastics(Withdrawn 1998)4D200
