Designation: D2000 − 18 Approved by Society of Automotive Engineers

SAE Recommended Practice J200

Standard Classification System for Rubber Products in Automotive Applications1

This standard is issued under the fixed designation D2000; 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 (´) 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 classification system covers the properties of vul-

canized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications.

NOTE 1—This classification system may serve many of the needs of other industries in much the same manner as SAE numbered steels. It must be remembered, however, that this system is subject to revision when required by automotive needs. It is recommended that the latest revision always be used.

1.2 This classification system is based on the premise that

the properties of all rubber products can be arranged into characteristic material designations. These designations are determined by types, based on resistance to heat aging, and classes, based on resistance to swelling in oil. Basic levels are thus established which, together with values describing addi-tional requirements, permit complete description of the quality of all elastomeric materials.

1.3 In all cases where the provisions of this classification

system would conflict with those of the detailed specifications for a particular product, the latter shall take precedence.

NOTE 2—When the rubber product is to be used for purposes where the requirements are too specific to be completely prescribed by this classi-fication system, it is necessary for the purchaser to consult the supplier in advance, to establish the appropriate properties, test methods, and speci-fication test limits.

1.4 The values stated in SI units are to be regarded as

standard.

1.5 This international standard was developed in accor-

dance with internationally recognized principles on standard-ization established in the Decision on Principles for the Development of International Standards, Guides and Recom-mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Purpose

3.1 The purpose of this classification system is to provide

guidance to the engineer in the selection of practical, commer-cially available rubber materials, and further to provide a method for specifying these materials by the use of a simple “line call-out” designation.

3.2 This classification system was developed to permit the

addition of descriptive values for future rubber materials without complete reorganization of the classification system and to facilitate the incorporation of future new test methods to keep pace with changing industry requirements.

4. Type and Class

4.1 The prefix letter “M” shall be used to indicate that the

classification system is based on SI units.

NOTE 3—Call outs not prefixed by the letter M refer to an earlier classification system based on inch-pound units. This was published in editions up to 1980.

4.2 Rubber materials shall be designated on the basis of type (heat resistance) and class (oil resistance). Type and class are indicated by letter designations as shown in Table 1 and Table 2 and illustrated in 9.1.

4.3 Type is based on changes in tensile strength of not more

than 630 %, elongation of not more than – 50 %, and hard-ness of not more than 615 points after heat aging for 70 h at an appropriate temperature. The temperatures at which these materials shall be tested for determining type are listed in Table 1.

4.4 Class is based on the resistance of the material to

swelling in IRM 903 Oil (most tables were originally devel-oped using ASTM Oil No. 3) after 70-h immersion at a temperature determined from Table 1, except that a maximum temperature of 150°C (the upper limit of oil stability) shall be used. Limits of swelling for each class are shown in Table 2.

4.4.1 ASTM No. 1, No. 2, and No. 3 Oils have been

replaced by IRM 901, 902, and 903 Oils, respectively, under Practice D5964. These oils are similar but not identical to ASTM No. 1, No. 2, and No. 3 Oils.

4.4.2 Substitutability of IRM 901, 902, and 903 Oils for

ASTM No. 1, No. 2, and No. 3 Oils has not been established, as their swelling characteristics are different and may affect compound classification.

NOTE 4—The selection of type based on heat resistance is understood to be indicative of the inherent heat resistance that can be normally expected from commercial compositions. Likewise, choice of class is based on the range of volume swell normally expected from such commercial compo-sitions as established by type. The fact that a type and class of material is listed in Table 6, under Basic Requirements, indicates that materials that meet these requirements for heat and oil resistance are commercially available.

4.5 The letter designations shall always be followed by a

three-digit number to specify the hardness and the tensile strength—for example, 505. The first digit indicates durometer

The next two digits indicate the minimum tensile strength—for example, 05 for 5 MPa, 14 for 14 MPa. Correlation of available materials for desired hardness and tensile strength is obtained through the elongation values in Table 6. See 7.2.

5. Grade Numbers, Suffix Letters, and Number

5.1 Grade Numbers—Since the basic requirements do not

always describe sufficiently all the necessary qualities, provi-sion is made for deviation or adding requirements through a system of prefix grade numbers. Grade No. 1 indicates that only the basic requirements are compulsory, and no suffix requirements are permitted. Grades other than No. 1 are used for expressing deviation or additional requirements and are listed as “Available Suffix Grade Numbers” in the last column under Basic Requirements in Table 6. A grade number is written as a material prefix number preceding the letters for type and class (see 9.1). Grade No. 1 is always an available suffix grade number, and thus is not referenced in the last column of each basic requirement table.

5.2 Suffıx Letters—The suffix letters that may be used, together with their meaning, appear in Table 3.

5.3 Suffıx Numbers—Each suffix letter should preferably be

followed by two suffix numbers (see Note 6 in 8.1). The first suffıx number always indicates the test method; time of test is part of the method and is taken from the listings in Table 5. The second suffıx number, if used, always indicates the temperature of test and is taken from Table 4. Where three-digit numbers are required, they are separated by a dash—for example: –10;

B4–10; F1–11.

6. Composition and Manufacture

6.1 This classification system is predicated upon materials

furnished under a specification based thereon being manufac-tured from natural rubber, reclaimed rubber, synthetic rubber, alone or in combination, together with added compounding ingredients of such nature and quantity as to produce vulcani-zates that comply with the specified requirements. All materials and workmanship shall be in accordance with good commer-cial practice, and the resulting product shall be free of porous areas, weak sections, bubbles, foreign matter, or other defects affecting serviceability.

6.2 Color—With the exception of FC, FE, FK, and GE

materials, the values in the material tables are based on black compounds and comparable values may not be available in color.

7. Basic Requirements

7.1 The basic requirements for physical properties specified

in Table 64 are based on values obtained from standard laboratory test specimens prepared and tested in accordance with the applicable ASTM test methods. Test results from specimens prepared from finished products may not duplicate values obtained from standard test specimens.

NOTE 5—When standard test specimens are cut from finished parts in accordance with Practice D3183, a deviation to the extent of 10 % (on tensile strength and elongation values only) is permissible when agreed upon by the purchaser and the supplier. This deviation is permissible only because of the recognized effects of knitting, grain, and buffing on the material when test specimens are prepared from finished parts and tested for tensile strength and elongation. When differences due to the method of processing or to the difficulty in obtaining suitable test specimens from the finished part arise, the purchaser and the supplier may agree on acceptable deviations. This can be done by comparing results of standard test specimens with those obtained on actual parts.

7.2 The available materials are listed in the appropriate

material section of the table, giving each hardness and tensile strength with its appropriate elongation value. Also, there is a repetition of the values for the basic heat and oil aging requirements for the material resulting from the assignment of type and class. In addition, values for compression set, nor-mally a basic requirement to ensure proper vulcanization, are specified.

7.3 Unless a suffix requirement is used to override an

existing basic requirement, the basic requirement applies.

8. Suffix Requirements

8.1 Suffix requirements shall be specified only as needed to

define qualities necessary to meet service requirements. These suffix requirements are set forth for the various grade numbers.

Suffix letters and suffix numbers describing these suffix re-quirements may be used singly or in combination, but not all suffıx values available for a given material need be specified.

NOTE 6—Examples of the use of suffix letters and numbers would be A14 and EO34. Suffix A (Table 3) stands for heat resistance, Suffix 1 (Table 5) specifies that the test be run in accordance with Test Method

4 Tensile values are shown as pounds per square inch in Table 6 for information only.

D573 for 70 h, and Suffix 4 (Table 4) indicates the temperature of test as 100°C. Similarly, Suffix EO34 indicates resistance in IRM 903 Oil in accordance with Test Method D471 for 70 h at 100°C.

8.1.1 Suffıx Letters “F” and “SR”—Additions have been

made to Table 3 and Table 5 for Suffix “F” and “SR”. SAE J200 convention requires available suffixes to be designated in the Table 6 “SUPPLEMENTARY (SUFFIX) REQUIRE- MENTS” section for each type and class of materials. J200 also requires round robin testing to verify requirements. Recent additions to “F” in Table 5, or the addition of “SR” to Table 3 and Table 5 will not undergo round robin testing, and thus will not be added to the Suffix Tables for each of the table grades AA thru KK. The additions are available for use, but should not be added to a line call-out without conferring with the user’s Material Group and agreement of the materials manufacturer.

Use of “F” or “SR” callouts that do not exist in the AA thru KK suffix tables must be specified with a “Z”:

Z1 = SR1x – which specifies Compression Stress Relaxation Test (x = test temperature from Table 5)

8.2 Basic requirements are always in effect, unless super-

seded by specific suffix requirements in the “line call-out.”

8.3 Use of Test Methods D1053 as a Suffix Requirement:

When specifying an F2 or F6 requirement, the line specifica-tion must define which T-values are required, along with the maximum allowed temperature. Test Methods D1053 proper-ties must then be less than or equal to the specified temperature for the corresponding T-value.

9. Line Call-Outs

9.1 A “line call-out,” which is a specification, shall contain:

the document’s names, the prefix letter M, the grade number, the material designation (type and class), and the hardness and tensile strength, followed by the appropriate suffix require-ments. Following is an example of a “line call-out” or specification:

ASTM D2000 M2BC 507 A14 EO34

ASTM D2000 = Standards Organization and Document Number

Basic Requirements:

M = Requirements are in SI Units.

2 = Applicable Suffix Grade.

B = Material Type based on Temperature Resistance.

C = Material Class based on IRM 903 Oil Volume Swell.

5 = x 10 is Type A Hardness (i.e., 5 indicates requirement is 50).

07 = Tensile Strength (“M” in line call out indicates units are in MPa).

Suffix Requirements:

A14 = A - Heat Resistance; 1 – D573, 70 h; 4 – 100°C EO34 = EO – Fluid Resistance in Oils and Lubricants; 3 – D471, IRM 903 Oil, 70 h; 4 – 100°C

In this example, basic requirements for heat resistance and fluid resistance are superseded by suffix requirements.

However, the basic requirement of 80 % for compression set, which is not included as a suffix requirement, is not superseded and therefore shall be met as specified in Table 6.

9.2 Incorporation of Test Methods D1053 F2 or F6 suffix

into a line call out.

ASTM D2000 M3HK810 A1-10 B37 EO78 Z1; Z1 = F2 (T5:-27,

T10:-29, T100:-37)

In this example the numbers following F2 represent the user desired T-values (T2, T5, T10, T50, and T100 are typical). In this case T5, T10, and T100 are the desired “T’s” to be reported. This example has an “M” denoting that all data is in metric, so the T-values are represented in degrees Centigrade (maximum temperature).

ASTM D2000 M3HK810 A1-10 B37 EO78 Z1; Z1 = F6 (-12,-14,2)

In this example the numbers following F6 represent T5, T10, and the maximum degrees of separation allowed between T10 and T5. This example has an “M” denoting that all data is in metric, so the T-values are represented in degrees Centigrade (maximum temperature).

10. Test Methods

10.1 The applicable test methods are listed in Table 5.

11. Sampling and Inspection

11.1 A lot, unless otherwise specified, shall consist of all

products of the same material submitted for inspection at the same time.

11.2 When proof of conformance with a specification based

on this classification system is required, the supplier shall, upon request of the purchaser at the time of ordering, furnish a sufficient number of samples to permit the performance of the required tests. Test specimens shall be prepared as prescribed in 7.1. The samples shall be warranted to have equivalent cure and to be from the same run or batch of compound used in the lot.
