| Название (англ.): | Plastics; Determination of viscosity number and limiting viscosity number; Part 4 : Polycarbonate (PC) moulding and extrusion materials |
| Описание (англ.): | Defines the particular conditions for the determination of the viscosity number and limiting viscosity number of polycarbonate (PC) moulding and extrusion materials, with reference to the guidelines for viscosity measurements in part 1 of this standard. Applies to homopolymers and copolymers of polycarbonates and to mixtures of the two, with or without filler. The measurement is carried out with a solution of 5 g/lpolycarbonate in dichloromethane. In the annex a description of the procedure of the verification of the accuracy of the viscosimeter is given |
