Designation:F10411Standard Classification System forNonmetallic Gasket Materials1This standard is issued under the fixed designation F104;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 Department of Defense.1.Scope1.1 This classification system2provides a means for speci-fying or describing pertinent properties of commercial nonme-tallic gasket materials.Materials composed of asbestos,cork,cellulose,and other organic or inorganic materials in combi-nation with various binders or impregnants are included.Materials normally classified as rubber compounds are notincluded,since they are covered in Classification D2000.Gasket coatings are not covered,since details thereof areintended to be given on engineering drawings or in separatespecifications.Facing materials for laminate composite gasketmaterials(LCGM)are included in Classification System F104.Assembled LCGMs are covered in Classification F868.1.2 Since all of the properties that contribute to gasketperformance are not included,use of the classification systemas a basis for selecting materials is limited.1.3 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.4 This standard does not purport to address all of thesafety 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:2C561 Test Method for Ash in a Graphite SampleD1170 Specification for Nonmetallic Gasket Materials forGeneral Automotive and Aeronautical Purposes(With-drawn 1968)3D2000 Classification System for Rubber Products in Auto-motive ApplicationsD5964 Practice for Rubber IRM 901,IRM 902,and IRM903 Replacement Oils forASTM No.1,ASTM No.2,andASTM No.3 OilsE11 Specification for Woven Wire Test Sieve Cloth and TestSievesF36 Test Method for Compressibility and Recovery of Gas-ket MaterialsF37 Test Methods for Sealability of Gasket MaterialsF38 Test Methods for Creep Relaxation of a Gasket MaterialF146 Test Methods for Fluid Resistance of Gasket MaterialsF147 Test Method for Flexibility of Non-Metallic GasketMaterialsF148 Test Method for Binder Durability of Cork Composi-tion Gasket MaterialsF152 Test Methods for Tension Testing of NonmetallicGasket MaterialsF433 Practice for Evaluating Thermal Conductivity of Gas-ket MaterialsF607 Test Method for Adhesion of Gasket Materials toMetal SurfacesF868 Classification for Laminated Composite Gasket Mate-rialsF1315 Test Method for Density of a Sheet Gasket MaterialG21 Practice for Determining Resistance of Synthetic Poly-meric Materials to Fungi3.Significance and Use3.1 This classification system is intended to encourageuniformity in reporting properties;to provide a commonlanguage for communications between suppliers and consum-ers;to guide engineers and designers in the test methodscommonly used for commercially available materials;and tobe versatile enough to cover new materials and test methods asthey are introduced.3.2 This system is based on the principle that nonmetallicgasket materials can be described in terms of specific physicaland mechanical properties.This enables the user,or producer,to characterize a nonmetallic gasket based on properties thatare important for the application.1This classification is under the jurisdiction of ASTM Committee F03 onGaskets and is the direct responsibility of Subcommittee F03.30 on Classification.Current edition approved April 1,2011.Published May 2011.Originallyapproved in 1968.Last previous edition approved in 2009 as F104 03(2009).DOI:10.1520/F0104-11.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Basis of Classification4.1 To permit“line call-out”of a materials physical andmechanical properties,this classification system establishesletter and number symbols for various performance levels ofeach property or characteristic.4.2 Each“line call out”shall include:-ASTM F104-In parentheses,the letter“F”followed by 6 numeralsdescribing the required basic characteristics per 8.1.-Within the same parentheses,a dash“-”shall follow the basiccharacteristics,along with any supplemental characteristics per8.2.All six(6)numeric fields defining the basic characteristicsmust be occupie
