Vacuum Sealing Techniques by Alexander Roth on p.105 says:
Deformation Point (D.P.). This is defined as the temperature observed during the measurement of the thermal expansion, at which the viscous flow of the glass exactly counteracts the thermal expansion (maximum point of the curve on Fig. 2.46). At this point the internal stresses are relieved in about 15 sec. The corresponding viscosity is 10^11.5 poises.
