Plastics. Determination of specific volume as a function of temperature and pressure (pVT diagram). Piston apparatus method Ingestion-build-47553 Interchange of quality data by1 Scope This International Standard describes procedures for determining the specific volume of plastics as a function of temperature and pressure in both the molten and solid states. The standard specifies the use of a piston equipped apparatus in which the test sample, held in a measurement cell, is pressurized by means of the piston. Measurements under conditions of constant pressure or constant temperature can be made. In the constant pressure
