ASTM D5927-03

Standard Specification for Thermoplastic Polyester (TPES) Injection and Extrusion Materials Based on ISO Test Methods

ABSTRACT
This specification is intended to provide a callout system for thermoplastic polyester (TPES) injection and extrusion materials, both virgin and recycled, based on ISO test methods. However, the proportions of recycled material used, and the nature and amount of any contaminant, as well as the selection of materials cannot be covered practically in this specification. Materials are classified into groups according to their composition, and are further subdivided into classes and grades as specified. Individual groups shall be identified in accordance to performance properties as to tensile strength, tensile modulus, Charpy impact strength, deflection temperature, melt flow rate, and density.
SCOPE
1.1 This specification covers thermoplastic polyester materials suitable for molding or extrusion.
1.2 This specification allows for the use of recycled thermoplastic polyester materials provided that the requirements as stated in this specification are met. The proportions of recycled material used, as well as the nature and amount of any contaminant, however, cannot be covered practically in this specification.
1.3 The properties included in this specification 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.
1.4 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 should be made by those having expertise in the plastic field after careful consideration of the design and performance required of the part, the environment to which it will be exposed, the fabrication process to be used, the costs involved, and the inherent properties of the material other than those covered by this specification.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 The following hazards caveat pertains only to the test methods portion, Section 11, 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 and health practices and determine the applicability of regulatory limitations prior to use.
Note 1—This specification is similar to ISO 7792-1:1995 and ISO 7792-2:1988, although the technical content is significantly different.
