ABSTRACT
This specification covers the requirements and test methods for the material, dimensions, and workmanship of extruded, compression molded, and injection molded basic shapes. The specimens shall be made of polyamide-imide which may be filled, lubricated, or reinforced with carbon, graphite, or glass fibers; lubricants such as PTFE, graphite, silicone, and molybdenum disulfide; mineral; combinations of reinforcements or fillers; or both. Tests shall be conducted in the standard laboratory conditions to determine the physical properties of the specimens. Physical properties shall conform to the ultimate tensile strength, elongation at break, tensile modulus, flexural modulus, Izod impact, glass transition temperature, and specific gravity requirements. Dimensional tests shall also be performed to determine the conformance of the specimens to the size thickness, thickness tolerance, camber length, and width bow specifications.
SCOPE
1.1 This specification covers requirements and methods of test for the material, dimensions, and workmanship of extruded, compression molded, and injection molded parts manufactured from PAI.  
1.2 The properties included in this specification are those required for the compositions covered. Requirements necessary to identify particular characteristics important to specialized applications are described by the classification system given in Section 5.  
1.3 This specification allows for the use of recycled materials provided that specification requirements based upon this specification are met.  
1.4 The values stated in English units are to be regarded as standard in all property and dimensional tables. For reference purposes, SI units and conversion factors are also included.  
1.5 The following precautionary caveat pertains only to the test method portion Section 12, of this specification. 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.

Overview

ASTM D7292-18 is the internationally recognized standard specification for extruded, compression-molded, and injection-molded basic shapes of polyamide-imide (PAI). Developed by ASTM International, this standard outlines requirements and testing methods for the material composition, dimensions, and workmanship of PAI shapes-such as rods, plates, sheets, and tubular bars-used in high-performance engineering applications. The scope of ASTM D7292-18 encompasses both virgin and recycled PAI materials, and includes grades that may be filled, lubricated, or reinforced with materials such as glass fibers, carbon fibers, graphite, PTFE, silicone, and molybdenum disulfide.

Key Topics

• Product Types: Covers extruded, compression-molded, and injection-molded PAI basic shapes.
• Material Composition: Specifies both unfilled and filled PAI; fillers and reinforcements can include glass fibers, carbon/graphite fibers, minerals, lubricants, or combinations.
• Testing Methods: Details standardized test methods for physical properties, including:
  • Ultimate tensile strength
  • Elongation at break
  • Tensile modulus
  • Flexural modulus
  • Izod impact resistance
  • Glass transition temperature (Tg)
  • Specific gravity
• Dimensional Tolerances: Provides specific requirements for size, thickness tolerance, camber, roundness, and width bow.
• Workmanship: Mandates that shapes are free from defects such as blisters, cracks, voids, foreign particles, and surface imperfections that limit commercial usability.
• Classification System: Utilizes a codified designation system based on type, class, and grade-facilitating customized material specifications by property set.
• Recycled Content: Permits use of recycled PAI, provided all specification requirements are met.
• Ordering and Certification: Sets requirements for product certification and order designation, ensuring traceability and quality assurance.

Applications

PAI shapes manufactured under ASTM D7292-18 are valued for their exceptional mechanical, thermal, and tribological properties. Key application areas include:

• Aerospace Components: Bearings, bushings, and seals requiring high thermal stability and wear resistance.
• Automotive Parts: Engine and transmission components exposed to elevated temperatures and demanding environments.
• Electrical Insulation: Plates and rods offering insulation, dimensional stability, and toughness.
• Industrial Equipment: Wear pads, gears, pump components, and low-friction machine parts.
• Medical Devices: Components where biocompatibility and high-performance plastics are required (subject to additional biocompatibility assessments).

Manufacturers and specifiers rely on ASTM D7292-18 to ensure PAI plastic shapes are fit for critical applications requiring reliability, durability, and compliance with rigorous specifications.

Related Standards

ASTM D7292-18 references several other important ASTM standards to define test methods, terminology, and classification systems for plastics and PAI materials. Relevant related standards include:

• ASTM D256: Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics
• ASTM D638: Test Method for Tensile Properties of Plastics
