BS 7034-1:1988

This standard BS 7034-1:1988 Viscosity and viscometric fixed points of glass is classified in these ICS categories:

• 81.040.01 Glass in general

This part of ISO 7884 gives rules for characterizing glass as a liquid (or liquid-analogue deformable) material with respect to its dynamic viscosity η and viscosity-temperature relationship, if it behaves as a Newtonian fluid.

NOTE Non-Newtonian behaviour may be observed sometimes in opaque glasses, vitreous enamels or highly crystallizing glasses (glass ceramics).
