Designation: F 104 03Standard Classification System forNonmetallic Gasket Materials1This standard is issued under the fixed designation F 104; 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 (e) 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 D 2000.Gasket coatings are not covered, since details thereof areintended to be given on engineering drawings or in separatespecifications. While the facing materials for laminate compos-ite gasket materials (LCGM) are included in ClassificationSystem F 104, materials normally classified as LCGM are notcovered since they are included in Classification F 868.1.2 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.

Significance and Use3.1 This classification is intended to encourage uniformityin reporting properties; to provide a common language forcommunications between suppliers and consumers; to guideengineers and designers in the test methods commonly used forcommercially available materials; and to be versatile enough tocover new materials and test methods as they are introduced.3.2 It is based on the principle that nonmetallic gasketmaterials should be described, insofar as is possible, in terms ofspecific physical and mechanical characteristics, and that aninfinite number of such descriptions can be formulated by useof one or more standard statements based on standard tests.Therefore, users of gasket materials can, by selecting differentcombinations of statements, specify different combinations of1This 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 10, 2003. Published May 2003. Originallyapproved in 1968. Last previous edition approved in 2002 as F 104 02e1.2Annual Book of ASTM Standards, Vol 09.02.3Annual Book of ASTM Standards, Vol 14.02.4Annual Book of ASTM Standards, Vol 14.04.1Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United Sperties desired in various parts. Suppliers, likewise, canreport properties available in their respective products.4. Basis of Classification4.1 To permit “line call-out” of the descriptions mentionedin 3.2, this classification system establishes letter or numbersymbols or both for various performance levels of eachproperty or characteristic (see Table 1)5.4.2 In specifying or describing gasket materials, each“ linecall-out” shall include the number of this system (minus datesymbol) followed by the letter “F” and six numerals, forexample: ASTM F 104 (F125400). Since each numeral of thecall-out represents a characteristic (as shown in Table 1), sixnumerals are always required. The numeral “0” is used whenthe description of any characteristic is not desired. The numeral“9” is used when the description of any characteristic (or testrelated thereto) is specified by some supplement to thisclassification system, such as notes on engineering drawings.4.3 To further specify or describe gasket materials, each“line call-out” may include one or more suffix letter-numeralsymbols, as listed in Table 2, for example: ASTM F104(F125400-B2M4). Various levels of definition may be estab-lished by increasing or decreasing the number of letter-numeralsymbols used in the “line call-out.”4.4 For convenience, gasket materials are referred to byType according to the principal fibrous or particulate reinforce-ment or other material from which the gasket is made and byClass according to the manufacturing method, or the commontrade designation. Type numbers correspond with the firstnumeral, and class numbers correspond with the secondnumeral of the basic six-digit line call-out, as shown in Table1.NOTE1While this “cell-type” format provides the means for closecharacterization and specification of each property and combinations ofproperties for a broad range of materials, it is subject to possiblemisapplications, since impossible property combinations can be coded ifthe user is not familiar with available commercial materials. Table X1.1 ofthis classification indicates properties, characteristics, and test methodsthat are normally considered applicable to each type of material.5. Physical and Mechanical Requirements5.1 Gasket materials identified by this classification shallhave the characteristics or properties indicated by the first sixnumerals of the line call-out, within the limits shown in Table1, and by additional letter-numeral symbols shown in Table 2.6. Thickness Requirements6.1 Gasket materials identified by this classification systemshall conform to the thickness tolerances specified in Table 3.7. Sampling7.1 Specimens shall be selected from finished gaskets orsheets of suitable size, whichever is the more practicable. Ifsheets are used, they shall, where applicable, be cut squarelywith the grain of the stock, and the grain direction shall benoted by an arrow. If finished gaskets are used, the dimensionsof sample and any variations from method must be reported.7.2 For qualification purposes, thickness shall be 0.8 mm(0.03 in.), except for Type 2, where the qualification thicknessis to be 1.5 to 6.4 mm (0.06 to 0.25 in.), and Type 5 Class 1,where the qualification thickness is to be 0.4 mm (0.015 in.).When thicknesses other than those shown above are to betested, the specification limits shall be agreed to in writingbetween the purchaser and the supplier.7.3 Sufficient specimens shall be selected to provide aminimum of three determinations for each test specified. Theaverage of the determinations shall be considered as the result.8. Conditioning8.1 Prior to all applicable tests, specimens shall be condi-tioned as follows:8.1.1 When the first numeral of line call-out is “1” (Type 1materials), specimens shall be conditioned in an oven at 100 62C (212 6 3.6F) for 1 h and allowed to cool to 21 to 30C(70 to 85F) in a desiccator containing anhydrous calciumchloride; except when second numeral of line call-out is “3”(Class 3 materials), the specimens shall be conditioned in anoven for 4 h at 100 6 2C (212 6 3.6F).8.1.2 When the first numeral of line callout is “2” (Type 2materials), specimens shall be conditioned at least 46 h in acontrolled-humidity room or in a closed chamber with gentlemechanical circulation of the air at 21 to 30C (70 to 85F) and50 to 55 % relative humidity.NOTE2If a mechanical means of maintaining 50 to 55 % relativehumidity is not available, a tray containing a saturated solution of reagentgrade magnesium nitrate, Mg(NO3)6H2O, shall be placed in the chamberto provide the required relative humidity.8.1.3 When the first numeral of line callout is “3” (Type 3materials), specimens shall be preconditioned for 4 h at 21 to30C (70 to 85F) in a closed chamber containing anhydrouscalcium chloride as a desiccant. The air in the chamber shall becirculated by gentle mechanical agitation. Specimens shall thenbe transferred immediately to a controlled-humidity room orclosed chamber with gentle mechanical circulation of the airand conditioned for at least 20 h at 21 to 30C (70 to 85F) and50 to 55 % relative humidity.8.1.4 When the first numeral of a line callout is “4,” noconditioning of specimens is necessary.8.1.5 When the first numeral of a line callout is “5,” “7,” or“8,” test specimens shall be conditioned in accordance with8.1.1 (Type 1 materials).8.1.6 When the first numeral of a line callout is “0” or “9,”specimens shall be conditioned as in 8.1.3, unless otherwisespecified in supplements to this classification.8.2 In all cases where testing is conducted outside the areaof specified humidity, specimens shall be removed from thechamber one at a time just prior to testing.9.
