ASTM D4066-13(2019)

Standard Classification System for Nylon Injection and Extrusion Materials (PA)

ABSTRACT
This classification system covers nylon injection and extrusion materials. Nylon materials are classified into groups according to their composition. Groups are further classified into classes and grades. Grades are identified by a single letter that indicates the reinforcement or filler used and two digits, in multiples of 5, which indicate the nominal quantity in weight percent. Specific requirements for variations of nylon materials shall be shown by a six-character designator. Suffixes shall be used for those properties not covered by basic requirements. Specific suffix requirements shall always take precedence over basic requirements. Tensile strength, flexural strength, Izod impact resistance, deflection temperature, and density shall be done on test pieces based on injection molded ISO 3167 type multipurpose test specimens. Conditioning, preparation, testing, inspection, packaging, and marking shall be in conformance to the requirements in this standard classification system.
SCOPE
1.1 This classification system covers nylon materials suitable for injection molding and extrusion. Some of these compositions are also suitable for compression molding and application from solution.  
1.2 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 may be specified by using the suffixes as given in Section 5.  
1.3 This classification system and subsequent line call-out (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the plastic field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this classification system.  
1.4 The values stated in SI units are to be regarded as the standard.  
1.5 The following precautionary caveat pertains only to the test methods portion, Section 11, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.
Note 2: This classification system is being revised to include international 4-mm specimens and test procedures as the standard for compliance. The 3.2-mm specimens; test methods; and Tables PA, A, and B are included in Appendix X3 as a reference for those wishing to use them. It is recommended that the material manufacturer be consulted on all call-outs against this classification system.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D4066-13(2019), Standard Classification System for Nylon Injection and Extrusion Materials (PA), is an internationally recognized standard developed by ASTM International. This classification system is designed to categorize nylon (polyamide, PA) materials principally used for injection molding and extrusion processes. The system allows for clear communication and specification between manufacturers, suppliers, and end-users by defining groups, classes, and grades based on material composition, reinforcement or filler, and crucial physical properties.

This standard plays a critical role in the plastics industry by offering a structured means of designating nylon materials based on standardized properties. It emphasizes the importance of proper material identification in the fabrication of end-use parts, rather than serving as a material selection guide.

Key Topics

• Material Classification: Nylon materials are categorized into groups by their chemical structure (e.g., PA 6, PA 66). Each group is subdivided into classes (such as general-purpose, heat-stabilized, impact-modified), and further into grades, which specify the type and quantity of reinforcement or filler (e.g., glass fiber, minerals).
• Six-Character Designator: Variations are defined using a six-character code, which enables precise specification of unique nylon compositions.
• Suffixes for Additional Properties: Suffixes may be added to denote properties or requirements not covered by the basic classification, such as electrical characteristics or color.
• Property Testing: Standardized test methods (using ISO 3167 multipurpose specimens) are specified for key properties, including tensile strength, flexural modulus, Izod impact resistance, deflection temperature under load, and density.
• Conditioning and Testing Protocols: Clear guidelines are provided for specimen conditioning, preparation, and standardized test procedures to ensure consistency and reliability in measured properties.
• Packaging and Marking: Requirements for proper packaging and labeling of materials are included to maintain quality throughout the supply chain.

Applications

ASTM D4066-13(2019) is essential for organizations involved in the design, manufacturing, or procurement of nylon-based parts and products. Its applications include:

• Automotive Components: Nylon materials classified under this standard are commonly used in under-the-hood parts, electrical connectors, fuel system components, and other automotive applications due to their mechanical and thermal properties.
• Consumer Goods: Products such as power tool housings, sports equipment, and appliance parts utilize classified nylon materials for consistent performance and durability.
• Electrical and Electronics: Nylon grades with specified electrical properties serve as insulation materials, connectors, and enclosures.
• Industrial Components: Gears, bearings, and casings benefit from the precise specification and repeatability enabled by the ASTM D4066 standard.

By following the guidelines and material call-outs of ASTM D4066, manufacturers ensure product consistency, regulatory compliance, and alignment with customer requirements in a global marketplace.

Related Standards

Users of ASTM D4066-13(2019) often reference other important standards, including:

• ASTM D6779: Standard Classification System for and Basis of Specification for Polyamide Molding and Extrusion Materials (PA); newer products are encouraged to use this standard for material selection and specification.
• ASTM D638: Determination of tensile properties for plastics.
• ASTM D790: Flexural properties of unreinforced and reinforced plastics.
• ASTM D256: Izod impact resistance test method.
• ISO 3167: Specification for multipurpose test specimens, referenced for specimen preparation.
• ISO 75, ISO 178, ISO 180: Determination of deflection temperature, flexural, and impact properties, respectively.

Note: There is no direct ISO equivalent to ASTM D4066 at this time. Users should always consult material manufacturers concerning specific call-outs and property requirements.

A
It is recognized that detailed test values, particularly Izod impact, may not predict nor even correlate with performance of parts molded of these materials.
B
Refer to 9.1 for source of test specimens.
C
Crosshead speed shall be 50 mm/min ± 10 % unless the specimen exhibits brittle failure (no yield point) and a strain at break of <10 % in which case crosshead speed
shall be 5 mm/min± 25 %.
D
If a specific value is required, it must appear on the drawing or contract, or both.
E
Deflection temperature shall be determined with the specimen in the flatwise position (Method A).
