Abstract

Disclosed is a method for calibrating an annular-shaped body which is made of thermoplastic or at least partially crystalline plastic material, to an annular-shaped body which is produced according to the method, and to an oscillating object which is used in the method. Also disclosed is an oscillating object which is used to stimulate oscillations and which is introduced into an annular-shaped body by means of axial forward motion. Localized warming of the annular-shaped body is performed until the glass transition temperature of the material thereof is exceeded by localized contact of the oscillating object with the annular-shaped body. A desired, economical internal measurement having high precision is produced when the calibration section of the oscillating body is immersed into the annular-shaped body.
