Anotace

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.
