Overview

ASTM D4067-23 is the internationally recognized standard for the classification and basis of specification for reinforced and filled poly(phenylene sulfide) (PPS) materials used in injection molding and extrusion processes. Published by ASTM International, this standard provides a system for designating PPS plastics based on key physical properties, ensuring clarity in material call-outs for manufacturing parts. It specifically addresses reinforced and filled PPS materials, offering an industry-accepted framework for specifying composition, reinforcement type and amount, and primary material properties. This standard is widely utilized in manufacturing sectors that require dependable, high-performance thermoplastics.

Key Topics

• Material Classification: Defines reinforced and filled PPS materials, allowing for precise identification and specification in production documents and procurement.
• Designation System: Uses an alphanumeric system to indicate base material, reinforcement type (e.g., glass, carbon fiber, minerals), filler content, and performance metrics such as tensile strength, flexural modulus, impact strength, flexural strength, and density.
• Physical Property Requirements: Ensures the materials meet minimum standards for mechanical performance, using recognized ASTM test methods.
• Suffix System: Allows for additional application-specific requirements, such as electrical properties, flammability ratings, or heat deflection temperatures, through standardized suffixes.
• Testing and Conformance: Outlines appropriate sample preparation, conditioning, and test methods for statistical control and quality assurance, referencing established ASTM protocols.
• Packaging and Marking: Details recommended practices for packaging and marking shipments to maintain material integrity and traceability.

Applications

ASTM D4067-23 serves a critical role in industries relying on high-performance engineering plastics:

• Automotive: Used for producing durable parts exposed to heat, chemicals, and mechanical stress, such as connectors, housings, and under-hood components.
• Electrical and Electronics: Specifies PPS grades where electrical insulation, flame resistance, and dimensional stability are vital, making the standard essential for circuit boards, insulators, and connectors.
• Aerospace: Employed for lightweight, strong, chemically resistant parts needing precise material specifications, including outgassing and smoke requirements.
• Industrial Equipment: Utilized in pumps, valves, and corrosion-resistant applications where reinforced PPS is specified for its mechanical and thermal stability.
• General Manufacturing: Supports procurement and compliance in any setting requiring well-defined, consistent PPS material properties for injection molding or extrusion.

By providing a common language for specifying reinforced and filled PPS plastics, the standard streamlines the supply chain, supports regulatory compliance, and ensures end-product reliability.

Related Standards

• ASTM D4000: General classification system for specifying plastic materials, which is referenced for more detailed suffix tables and additional characteristic requirements in ASTM D4067-23.
• ASTM D6358: Offers a similar classification system for PPS materials but utilizes ISO test methods, recommended for those seeking alignment with international testing practices.
• ASTM D638 / D790 / D256 / D792: Standardized methods referenced for testing tensile properties, flexural properties, impact resistance, and density of plastics, respectively.
• Military Standards: MIL-P-46174 and MIL-M-24519 (now largely replaced or cross-referenced to ASTM D4067-23) for PPS plastics in defense applications.
• ISO 527–2 / ISO 3451: International equivalents for tensile property and ash content determination, often referenced for procurement outside the U.S.

Practical Value

Implementing ASTM D4067-23 in procurement and manufacturing:

• Reduces Ambiguity: Clear designation and properties control help prevent material mix-ups and enable transparent communication throughout the value chain.
• Supports Quality Assurance: Standardized test requirements and statistical sampling ensure consistent material performance.
• Facilitates Regulatory Compliance: Alignment with global trade principles and cross-referencing to military and ISO standards supports legal and industry-mandated requirements.

G40 = glass-reinforced at 40 % nominal level,
A = Table A physical property requirements,
4 = tensile strength, min 120 MPa,
2 = flexural modulus, min 10 000 MPa,
0 = Izod impact strength, unspecified,
4 = flexural strength, min 165 MPa, and
3 = density, min 1.60 g/cm .
If no properties are specified, the designation would be ASTM D4067 PPS0000G40A00000.
5. Suffixes
5.1 When additional requirements are needed that are not covered by the basic requirements or cell table requirements, they shall
be indicated through the use of suffixes. Electrical, flammability or other requirements shall be designated by the appropriate suffix
from Table 3 of Classification System D4000.
NOTE 6—The denotion of electrical property requirements changed from an independent table of electrical properties in the 1996 version of this standard
with its own nomenclature for suffixes, to referring to ASTM Standard D4000 electrical property suffix requirements in 2011 and subsequent revisions.
Where the older suffix nomenclature such as E00, E01, E02, etc have been used on engineering drawings, these suffixes are not consistent with suffixes
used in Table 3 of D4000. The material classification used in such cases should refer to the 1996 version of this standard, as for example, “ASTM
D4067-96 PPS0000G40A42043E01” or as “ASTM D4067 PPS0000G40A42043E01 per ASTM D4067-96”. The table of electrical properties from
ASTM D4096-96 is included as Appendix X2 in this standard.
5.1.1 If applicable, heat deflection temperature shall be designated using the following suffix:
Y = Heat deflection temperature as designated by the following digits:
First Digit
1 = Test Method D648, 1820 kPa
Second Digit
1 = minimum of 260°C
2 = other minimum temperature (°C) - specify
NOTE 7—Heat treating the test specimens at 260°C for 4 h is permitted to achieve high heat deflection temperatures.
6. Basic Requirements
6.1 Basic requirements from Table A, as they apply, are always in effect unless superseded by specific suffix requirements, which
always take precedence.

7. General Requirements
7.1 The plastics composition shall be uniform and shall conform to the requirements specified herein. The color and form of the
material shall be as agreed upon between the supplier and the user.
8. Detail Requirements
8.1 Test specimens for the various materials shall conform to the requirements prescribed in Table A and suffix requirements as
they apply.
8.2 For the purpose of determining conformance with this classification system, all specified limits in this classification system
are absolute limits, as defined in Practice E29.
8.2.1 In the absolute method, an observed value or a calculated value is not rounded off, but is to be compared directly to the
specified limiting value. Conformance or nonconformance with the specification is based on this comparison.
9. Sampling
9.1 Sampling shall be statistically adequate to satisfy the requirements of 13.4.
9.2 A batch or lot is construed as a unit of manufacture as prepared for shipment and can consist of a blend of two or more
“production runs.”
10. Specimen Preparation
