Scope

The document specifies a method of determining the dynamic viscosity of glass on a rod-shaped test specimen (called a beam) supported at its end. The viscous deflection rate of the beam is measured under given load at the midpoint between the supports. In addition the viscosity-temperature relationship and the dependence of the viscosity on the thermal history of the sample can be determined.
