Standard Specification for Polycarbonate (PC) Unfilled and Reinforced Material
ABSTRACT
This specification 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. Unfilled polycarbonate materials are classified into groups according to their composition. The groups are Group 01, Group 02, Group 03, Group 04, Group 05, and Group 06. These groups are subdivided into classes which are Class 0, Class 1, Class 2, Class 3, and Class 4 and these classes can be further be subdivided into grades which are Grade 1, Grade 2, Grade 3, Grade 4, Grade 5, Grade 6, Grade 7 and Grade 0. Different tests shall be conducted in order to determine the following properties of polymer materials: Izod impact strength, flexural modulus, tensile strength, and deflection temperature.
SCOPE
1.1 This specification 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.
1.2 The properties in this specification are those required for identifying the compositions covered. There may be other requirements necessary for identifying particular characteristics important to specific applications. Those may be specified by using the suffixes in accordance with Section 5.
1.3 The values stated in SI units are to be regarded as the standard.
Note 1—This specification and ISO 7391-1 and ISO 7391-2 address the same subject matter, but differ in technical content.
1.4 The following hazards caveat pertains only to the test methods portion, Section 12, of this specification. This standard does not purport to address all 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 or regulatory limitations prior to use.
