ASTM D4673-02(2008)

Standard Classification System for Acrylonitrile-Butadiene-Styrene (ABS) Plastics and Alloys Molding and Extrusion Materials

ABSTRACT
This classification system covers only acrylonitrile-butadiene-styrene (ABS) materials and ABS alloys suitable for injection molding and extrusion. Some of these compositions may also be suitable for compression molding. Recycle ABS and alloys will be addressed in a separate standard. ABS materials, based on three or more monomers, are grouped rather than rigidly classified. These groups are then subdivided by class and then grades. Reinforced and lubricated versions of the ABS materials are classified. When the grade of the basic material is not known, or is not important, the use of "0" grade classification shall be used for reinforced materials in this system. The material composition shall be uniform and shall conform to the requirements specified. Test specimens and testing parameters for the materials shall conform to the requirements prescribed. The tensile strength at yield, modulus, Charpy impact, vicat softening point, heat deflection temperature, and glass content of glass-reinforced materials shall be tested to meet the requirements prescribed.
SCOPE
1.1 This classification system covers only ABS materials and ABS alloys suitable for injection molding and extrusion. Some of these compositions may also be suitable for compression molding. Recycle ABS and alloys will be addressed in a separate standard.
1.2 This classification system is not intended for the selection of materials, but only as a means of calling out materials to be used in the manufacture of parts. Materials are to be selected by personnel with expertise in the plastics field where the economics, the environment to be encountered, the inherent properties of the materials, the part design, the part performance required, and the manufacturing process to be employed all enter into the selection.
1.3 The properties included in this classification system are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These will be agreed upon between the user and the supplier by using the suffixes given in Section 5.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.5 The following precautionary caveat pertains only to the test methods portion, Section 12, of this classification system: 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.
Note 1—This classification system and ISO 2580 are technically equivalent for those tests contained in both standards.

Molding and Extrusion Materials
This standard is issued under the fixed designation D 4673; 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 Department of Defense.
1. Scope*
1.1 This classification system covers only ABS materials and ABS alloys suitable for injection molding and extrusion. Some
of these compositions may also be suitable for compression molding. Recycle ABS and alloys will be addressed in a separate
standard.
1.2 This classification system is not intended for the selection of materials, but only as a means of calling out materials to be
used in the manufacture of parts. Materials are to be selected by personnel with expertise in the plastics field where the economics,
the environment to be encountered, the inherent properties of the materials, the part design, the part performance required, and the
manufacturing process to be employed all enter into the selection.
1.3 The properties included in this classification system are those required to identify the compositions covered. There may be
other requirements necessary to identify particular characteristics important to specialized applications. These will be agreed upon
between the user and the supplier by using the suffixes given in Section 5.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 The following precautionary caveat pertains only to the test methods portion, Section 12, of this classification system: 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.
NOTE 1—This classification system and ISO 2580 are technically equivalent for those tests contained in both standards.

NOTE 2—An example of this classification system is as follows:
D 4673 – 02 (2008)
The designation ABS0111 would indicate:
ABS = acrylonitrile–butadiene–styrene,
01 (group) = injection-molding resin,
1 (class) = medium impact, and
1 (grade) = requirements given in Table ABS.
4.1.1 To facilitate the incorporation of future or special materials, the “other/unspecified” category (0) for group, class, and
grade is shown in Table ABS. The basic properties can be obtained from Cell Table A, B, and C as they apply.
4.2 ReinforcedandlubricatedversionsoftheABSmaterialsareclassifiedinaccordancewithTableABSandCellTableA.Table
ABS specifies the unreinforced material and Cell Table A specifies the properties by either ASTM or ISO procedures after the
addition of reinforcements or lubricants at the nominal level indicated.
4.2.1 A single letter shall be used for the major reinforcement or combination, or both, along with two digits that indicate the
percentage of addition by mass, with the tolerance as tabulated below:
Symbol Material Tolerance
C Carbon- and graphite-fiber reinforced 62%
G Glass-reinforced 62%
L Lubricants (for example, depends on material and
PTFE), graphite, silicone process—to be speci-
and molybdenum disulfide fied
M Mineral-reinforced 6 2%
R Combinations of reinforcements or 6 3 % for the total rein-
fillers, or both forcement
NOTE 3—This part of the system uses percent of reinforcements or additives, or both, in the callout of the modified basic material. The types and
percentages of reinforcements and additives should be shown on the supplier’s technical data sheet unless this information is proprietary in nature.If
necessary, additional callout of these reinforcements and additives can be accomplished by the use of the suffix part of the system as described in Section
8.
4.2.2 Specific requirements for reinforced, filled, or lubricated materials shall be shown by a six-character designation. The
designation shall consist of the letterAand the five digits comprising the cell numbers for the property requirements in the order
in which they appear in Cell Table A.

4.2.2.1 Although the values listed are necessary to include the range of properties available in existing materials, users should
not infer that every possible combination of the properties exists or can be obtained.
4.2.3 When the grade of the basic material is not known, or is not important, the use of “0” grade classification shall be used
for reinforced materials in this system.
NOTE 4—An example of this classification for a reinforced ABS is as follows:
The designation ABS 120G30A55130 indicates:
ABS 120 = Acrylonitrile-butadiene-styrene, molding resin, high impact
G30 = Glass reinforced at 30 % nominal level,
A = Cell Table A, property requirements,

1 = 30 J/m Izod or 2 kj/m Charpy impact strength, min,
3 = 90°C heat deflection temperature, D 648, 89°C, ISO 75 min, and
0 = unspecified.
If no properties are specified, the designation would be ABS 120G30A00000.

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
An American National Standard Designation: D 4673 – 02 (Reapproved 2008)
Designation:D4673–98
Standard Classification System for
Acrylonitrile–Butadiene–Styrene (ABS) Plastics and Alloys
Molding and Extrusion Materials
This standard is issued under the fixed designation D 4673; 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 Department of Defense.
1. Scope*
1.1 This classification system covers only ABS materials and ABS alloys suitable for injection molding and extrusion. Some
of these compositions may also be suitable for compression molding. Recycle ABS and alloys will be addressed in a separate
standard.
1.2 This classification system is not intended for the selection of materials, but only as a means of calling out materials to be
used in the manufacture of parts. Materials are to be selected by personnel with expertise in the plastics field where the economics,
the environment to be encountered, the inherent properties of the materials, the part design, the part performance required, and the
manufacturing process to be employed all enter into the selection.
1.3The1.3 The properties included in this classification system are those required to identify the compositions covered. There
may be other requirements necessary to identify particular characteristics important to specialized applications. These will be
agreed upon between the user and the supplier by using the suffixes given in Section 5.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 The following precautionary caveat pertains only to the test methods portion, Section 12, of this classification system: 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.
NOTE 1—This classification system and ISO 2580 are technically equivalent for those tests contained in both standards.

Plating grades are those specifically recommended for plating or sputtering applications.
F
Clear ABS has a light transmission of 70 % minimum. It may be tested using Test Method D 1003.
G
Specific flammability requirements shall be specified by the user.
NOTE 2—An example of this classification system is as follows:
The designation ABS0111 would indicate:
ABS = acrylonitrile–butadiene–styrene,
01 (group) = injection-molding resin,
1 (class) = medium impact, and
1 (grade) = requirements given in Table ABS.
4.1.1 To facilitate the incorporation of future or special materials, the “other/unspecified” category (0) for group, class, and
grade is shown in Table ABS. The basic properties can be obtained from Cell Table A, B, and C as they apply.
4.2 ReinforcedandlubricatedversionsoftheABSmaterialsareclassifiedinaccordancewithTableABSandCellTableA.Table
ABS specifies the unreinforced material and Cell Table A specifies the properties by either ASTM or ISO procedures after the
addition of reinforcements or lubricants at the nominal level indicated.
4.2.1 A single letter shall be used for the major reinforcement or combination, or both, along with two digits that indicate the
percentage of addition by mass, with the tolerance as tabulated below:
Symbol Material Tolerance
C Carbon- and graphite-fiber reinforced 62%
G Glass-reinforced 62%
L Lubricants (for example, depends on material and
PTFE), graphite, silicone process—to be speci-
and molybdenum disulfide fied
M Mineral-reinforced 6 2%
R Combinations of reinforcements or 6 3 % for the total rein-
fillers, or both forcement
NOTE 3—This part of the system uses percent of reinforcements or additives, or both, in the callout of the modified basic material. The types and
percentages of reinforcements and additives should be shown on the supplier’s technical data sheet unless this information is proprietary in nature.If
necessary, additional callout of these reinforcements and additives can be accomplished by the use of the suffix part of the system as described in Section
8.
4.2.2 Specific requirements for reinforced, filled, or lubricated materials shall be shown by a six-character designation. The
designation shall consist of the letterAand the five digits comprising the cell numbers for the property requirements in the order
