(Specification)Standard Specification for Extruded, Compression-Molded, and Injection-Molded Basic Shapes of Polyamide-Imide (PAI)
Standard Specification for Extruded, Compression-Molded, and Injection-Molded Basic Shapes of Polyamide-Imide (PAI)
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.
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.
