- Scope
- The document specifies a method of determining the working point of glass by means of the sinkimg bar viscometer. The method has been found useful for characterizing the low-viscosity range of glass working. This viscometric fixed point can be used in determining the viscosity-temperature relationship (see DIN ISO 7884-1). This method is applicable to all glasses of normal bulk-produktion compositions unless devitrification or evaporation of volatile components takes place during the preparation or testing of the specimen.
