CSA Group Glass - Viscosity and viscometric fixed points - Part 4: Determination of viscosity by beam bending ISO 7884-4:1987

Description
A method of determining the dynamic viscosity of glass on a rod-shaped test specimen, i.e. a beam, supported at its end is specified. The viscous deflection rate of the beam is measured under given load at the midpoint between the supports. In addition the viscosity-temperatur e relationship and the dependence of the viscosity on the thermal history of the sample can be determined. The theoretical basis relations and the apparatus including method of measurements are described.
