Scope

1.1 This classification system covers unfilled and reinforced polycarbonate and polycarbonate copolymer materials suitable for injection molding, blow molding, and extrusion. Some of these compositions may also find use for compression molding or application from solution. This classification system allows for the use of recycled materials provided that all specification requirements are met. 1.2 The properties in this classification system are those required for identifying the compositions covered. Other requirements necessary for identifying particular characteristics important to specific applications are normally specified by using the suffixes in accordance with Section 5. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 only after 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 in this standard. NOTE 1—This classification system and ISO 21305-1 and ISO 21305-2 address the same subject matter, but differ in technical content. 1.5 The following precautionary caveat pertains only to the test methods portion, Section 12, 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. 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.
