Pagination or Media Count:
In order to establish realistic design criteria applicable to several special glasses certain physical properties have been determined throughout their useful temperature range. Data are presented on the stress-rupture and creep at room temperature, 700 F, and a temperature 50 C below the strain point for 7900 and 7940. Data on the modulus of rupture and modulus of elasticity of Pittsburgh Plate Glass 6695 are presented over the temperature range from 75 F to above the strain point of the glass. An analysis of the mirror surface modulus of rupture relationship for the glasses tested in the program is presented. Author
