Designation: F 104 – 03

Standard Classification System for

Nonmetallic Gasket Materials

1

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 system

2

provides 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 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

compos-ite 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

appro-priate safety and health practices and determine the

applica-bility of regulatory limitations prior to use.

3. 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

1This classification is under the jurisdiction of ASTM Committee F03 on

Gaskets and is the direct responsibility of Subcommittee F03.30 on Classification. Current edition approved April 10, 2003. Published May 2003. Originally approved in 1968. Last previous edition approved in 2002 as F 104 – 02e1.

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

estab-lished 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

reinforce-ment 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.

OTE

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.

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

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.

8. Conditioning

8.1 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 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.

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(NO

3

)·6H

2

O, shall be placed in the chamber

to provide the required relative humidity.

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.

9. Test Methods

9.1 Thickness:

9.1.1 Measure the specimens with a device actuated by a

dead-weight load. The device shall be capable of reading in
