Designation: F 104 – 03

Standard Classification System for

Nonmetallic Gasket Materials1 This standard is issued under the fixed designation F 104; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript 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. Scope 1.1 This classification system2 provides a means for specifying or describing pertinent properties of commercial nonmetallic gasket materials. Materials composed of asbestos, cork, cellulose, and other organic or inorganic materials in combination with various binders or impregnants are included. Materials normally classified as rubber compounds are not included, since they are covered in Classification D 2000. Gasket coatings are not covered, since details thereof are intended to be given on engineering drawings or in separate specifications. While the facing materials for laminate composite gasket materials (LCGM) are included in Classification System F 104, materials normally classified as LCGM are not covered since they are included in Classification F 868. 1.2 Since all of the properties that contribute to gasket performance are not included, use of the classification system as a basis for selecting materials is limited. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use 3.1 This classification is intended to encourage uniformity in reporting properties; to provide a common language for communications between suppliers and consumers; to guide engineers and designers in the test methods commonly used for commercially available materials; and to be versatile enough to cover new materials and test methods as they are introduced. 3.2 It is based on the principle that nonmetallic gasket materials should be described, insofar as is possible, in terms of specific physical and mechanical characteristics, and that an infinite number of such descriptions can be formulated by use of one or more standard statements based on standard tests. Therefore, users of gasket materials can, by selecting different combinations of statements, specify different combinations of

F 104 – 03 sheets are used, they shall, where applicable, be cut squarely with the grain of the stock, and the grain direction shall be noted by an arrow. If finished gaskets are used, the dimensions of 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 thickness is 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 be tested, the specification limits shall be agreed to in writing between the purchaser and the supplier. 7.3 Sufficient specimens shall be selected to provide a minimum of three determinations for each test specified. The average of the determinations shall be considered as the result.

properties desired in various parts. Suppliers, likewise, can report properties available in their respective products. 4. Basis of Classification 4.1 To permit “line call-out” of the descriptions mentioned in 3.2, this classification system establishes letter or number symbols or both for various performance levels of each property or characteristic (see Table 1)5 . 4.2 In specifying or describing gasket materials, each“ line call-out” shall include the number of this system (minus date symbol) followed by the letter “F” and six numerals, for example: ASTM F 104 (F125400). Since each numeral of the call-out represents a characteristic (as shown in Table 1), six numerals are always required. The numeral “0” is used when the description of any characteristic is not desired. The numeral “9” is used when the description of any characteristic (or test related thereto) is specified by some supplement to this classification 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-numeral symbols, as listed in Table 2, for example: ASTM F104 (F125400-B2M4). Various levels of definition may be established by increasing or decreasing the number of letter-numeral symbols used in the “line call-out.” 4.4 For convenience, gasket materials are referred to by Type according to the principal fibrous or particulate reinforcement or other material from which the gasket is made and by Class according to the manufacturing method, or the common trade designation. Type numbers correspond with the first numeral, and class numbers correspond with the second numeral of the basic six-digit line call-out, as shown in Table 1.

8. Conditioning 8.1 Prior to all applicable tests, specimens shall be conditioned as follows: 8.1.1 When the first numeral of line call-out is “1” (Type 1 materials), specimens shall be conditioned in an oven at 100 6 2°C (212 6 3.6°F) for 1 h and allowed to cool to 21 to 30°C (70 to 85°F) in a desiccator containing anhydrous calcium chloride; except when second numeral of line call-out is “3” (Class 3 materials), the specimens shall be conditioned in an oven for 4 h at 100 6 2°C (212 6 3.6°F). 8.1.2 When the first numeral of line callout is “2” (Type 2 materials), specimens shall be conditioned at least 46 h in a controlled-humidity room or in a closed chamber with gentle mechanical circulation of the air at 21 to 30°C (70 to 85°F) and 50 to 55 % relative humidity. NOTE 2—If a mechanical means of maintaining 50 to 55 % relative humidity is not available, a tray containing a saturated solution of reagent grade magnesium nitrate, Mg(NO3)·6H2O, shall be placed in the chamber to provide the required relative humidity.

NOTE 1—While this “cell-type” format provides the means for close characterization and specification of each property and combinations of properties for a broad range of materials, it is subject to possible misapplications, since impossible property combinations can be coded if the user is not familiar with available commercial materials. Table X1.1 of this classification indicates properties, characteristics, and test methods that are normally considered applicable to each type of material.

8.1.3 When the first numeral of line callout is “3” (Type 3 materials), specimens shall be preconditioned for 4 h at 21 to 30°C (70 to 85°F) in a closed chamber containing anhydrous calcium chloride as a desiccant. The air in the chamber shall be circulated by gentle mechanical agitation. Specimens shall then be transferred immediately to a controlled-humidity room or closed chamber with gentle mechanical circulation of the air and conditioned for at least 20 h at 21 to 30°C (70 to 85°F) and 50 to 55 % relative humidity. 8.1.4 When the first numeral of a line callout is “4,” no conditioning 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 with 8.1.1 (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 otherwise specified in supplements to this classification. 8.2 In all cases where testing is conducted outside the area of specified humidity, specimens shall be removed from the chamber one at a time just prior to testing.

5. Physical and Mechanical Requirements 5.1 Gasket materials identified by this classification shall have the characteristics or properties indicated by the first six numerals of the line call-out, within the limits shown in Table 1, and by additional letter-numeral symbols shown in Table 2. 6. Thickness Requirements 6.1 Gasket materials identified by this classification system shall conform to the thickness tolerances specified in Table 3. 7. Sampling 7.1 Specimens shall be selected from finished gaskets or sheets of suitable size, whichever is the more practicable. If
