ASTM D6358-19e1

Standard Classification System and Basis for Specification for Poly (Phenylene Sulfide) (PPS) Injection Molding, Extrusion and Blow Molding Materials Using ISO Methods

SCOPE
1.1 This classification system covers unfilled, reinforced filled, and impact modified materials suitable for injection molding, extrusion and blow molding using ISO methods. The system allows for the use of poly (phenylene sulfide) (PPS) plastic materials that are recycled, reconstituted recycled-regrind, recovered or reprocessed, or both, provided that the requirements as stated in this specification are met. It is the responsibility of the supplier and the buyer of recycled, reconstituted, recycled-regrind, recovered or reprocessed, or both, poly (phenylene sulfide) plastic materials to ensure compliance (see Guide D7209).  
1.2 The properties included in this classification are those required to identify the compositions covered. It is possible that other requirements are necessary to identify particular characteristics important to specialized applications. The use of suffixes as shown in Section 5 is one way of specifying these requirements.  
1.3 This classification system and subsequent line callout (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 needs to 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.  
1.4 The following precautionary caveat pertains only to the test method 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: This standard and ISO 28078 address the same subject matter, but differ in technical content.
Note 2: ASTM D4067 for PPS uses ASTM test methods.  
1.5 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 D6358-19e1: Standard Classification System and Basis for Specification for Poly (Phenylene Sulfide) (PPS) Injection Molding, Extrusion, and Blow Molding Materials Using ISO Methods provides a structured approach to classifying and specifying poly(phenylene sulfide) (PPS) plastics for use in injection molding, extrusion, and blow molding processes. Developed by ASTM International, this standard offers a comprehensive framework for identifying unfilled, reinforced, impact-modified, and recycled PPS materials that comply with strict property and performance requirements.

The standard is relevant for manufacturers, suppliers, and buyers seeking consistent, high-quality PPS materials for industrial applications. By utilizing ISO test methods, ASTM D6358-19e1 ensures international compatibility, making it particularly valuable for global supply chains and cross-border commerce involving PPS plastics.

Key Topics

• Material Classes and Grades: Covers unfilled, reinforced (including glass, carbon, and mineral-reinforced), impact-modified, toughened, and special purpose PPS materials.
• Recycled and Reprocessed Content: Allows the use of recycled, reconstituted, recovered, or reprocessed PPS, provided compliance with all specified requirements.
• Specification System: Utilizes a system of group, class, and grade designations, including suffixes for additional requirements, to precisely define material properties.
• Test Methods: Relies on ISO methods for characterization, ensuring repeatable and verifiable results across laboratories.
• Identification Properties: Focuses on properties like tensile strength, flexural modulus and strength, impact resistance, and density to enable accurate material identification.
• Inspection and Certification: Details requirements for lot-acceptance inspection, periodic verification, and supplier certification, ensuring ongoing material quality.
• Safety and Best Practices: Emphasizes the responsibility of users to establish and adhere to appropriate safety, health, and environmental protocols.

Applications

ASTM D6358-19e1 is primarily applied in industries that require precise control over material properties for manufactured plastic components. Key use cases include:

• Automotive Components: Suitable for high-performance under-the-hood parts, connectors, and structural elements, benefiting from PPS's thermal and chemical resistance.
• Electrical and Electronic Devices: PPS's dimensional stability and electrical insulating properties make it ideal for switchgear, circuit components, and housings.
• Industrial Machinery and Appliances: Utilized in pump housings, valve bodies, filter components, and other applications demanding mechanical strength and chemical resistance.
• Consumer Products: Blow-molded and extruded consumer parts benefit from the durability and consistent quality achievable under this standard.
• Sustainable Manufacturing: Supports circular economy efforts by permitting recycled and reprocessed PPS materials when they meet quality criteria.

By following ASTM D6358-19e1, manufacturers and buyers gain a standardized approach to specifying and verifying PPS material quality, enhancing product reliability and streamlining procurement in accordance with international standards.
