CONTAINED IN VOL. 15.02, 2017 Defines the determination of glass viscosity from approximately 10[8] Pa.s to approximately 10[13] Pa.s by measuring the rate of viscous bending of a simply loaded glass beam.

1.1 This test method covers the determination of glass viscosity from approximately 10⁸ Pa·s to approximately 10¹³ Pa·s by measuring the rate of viscous bending of a simply loaded glass beam. Due to the thermal history of the glass, the viscosity may not represent conditions of thermal equilibrium at the high end of the measured viscosity range. Measurements carried out over extended periods of time at any temperature or thermal preconditioning will minimize these effects by allowing the glass to approach equilibrium structural conditions. Conversely, the method also may be used in experimental programs that focus on nonequilibrium conditions.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
