Designation:F49314Standard Specification forSolvent Cements for Chlorinated Poly(Vinyl Chloride)(CPVC)Plastic Pipe and Fittings1This standard is issued under the fixed designation F493;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification provides requirements for chlorinatedpoly(vinyl chloride)(CPVC)solvent cements to be used injoining chlorinated poly(vinyl chloride)pipe,tubing,andsocket-type fittings.1.2 CPVC solvent cements are used with CPVC 41 chlori-nated poly(vinyl chloride)pipe,tubing,and fittings,whichmeet Class 23447 as defined in Specification D1784.1.3 A recommended procedure for joining CPVC pipe andfittings is given in Appendix X1.1.4 The text of this specification references notes,footnotes,and appendixes which provide explanatory material.Thesenotes and footnotes(excluding those in tables and figures)shallnot be considered as requirements of the specification.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 The following safety hazards caveat pertains only to thetest methods portion,Section 6,of this specification:Thisstandard does not purport to address all of 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.Referenced Documents2.1 ASTM Standards:2D1084 Test Methods for Viscosity of AdhesivesD1598 Test

ComponentsHealth Effects33.Terminology3.1 DefinitionsThe definitions in this specification are inaccordance with Terminology F412.4.General Requirements4.1 The solvent cement shall be a solution of the base CPVCresin used to make Class 23447,chlorinated poly(vinyl chlo-ride)molding or extrusion compound as defined in Specifica-tion D1784.4.2 When rework material is used,the manufacturer shalluse only his own clean rework material that is compatible withvirgin material and produces a cement that meets the require-ments of this specification.4.3 The cement shall be free-flowing and shall not containlumps,undissolved resin,or any foreign matter that willadversely affect the ultimate joint strength or chemical resis-tance of the cement.1This specification is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.20 on Joining.Current edition approved Nov.1,2014.Published December 2014.Originallyapproved in 1977.Last previous edition approved in 2010 as F493 10.DOI:10.1520/F0493-14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book

States1 4.4 The cement shall show no gelation or stratification thatcannot be removed by stirring.4.5 When inert fillers and colorants are added,the resultingcement shall meet all requirements of this specification.NOTE1It is recommended that CPVC solvent cement be orange incolor to facilitate identification and minimize unintentional use of othercements that may fail at elevated service temperatures.4.6 The particular solvent system to be used in the formu-lation of this solvent cement is not specified,since it isrecognized that a number of adequate solvent systems forCPVC exist.Solvent systems consisting of blends of tetrahy-drofuran and cyclohexanone have been found to make cements
