Rules a given characterizing glass as a liquid (or liquid-analogue deformable) material. Three ranges of viscosity can be distinguished: melting, working and annealing range. General requirements for measurement and calibration, for apparatus and for sampling are specified. The formulae for calculating the different values are described. In annex A tables for estimating the influence of errors in viscosity and temperature determination and in annex B examples of certified reference glasses are shown.
