ASTM E671-98-Reapproved2016<\/h3>\n

Historical Standard: Standard Specification for Maximum Permissible Thermal Residual Stress in Annealed Glass Laboratory Apparatus<\/h4>\n
\n

ASTM E671<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This specification covers a limit for thermal residual stress in reusable annealed glass laboratory apparatus as determined by prescribed photoelastic measurement procedures.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> In broad classification, the laboratory glassware items covered by this specification, but not limited to, are:<\/p>\n

\n <\/div>\n<\/p><\/div>\n
\n

1.3<\/span> This specification recognizes that photoelastic measurements are proportional to the difference of the principal stresses. The limit imposed represents a safety factor to cover a situation in which one of the principal stresses may be larger than the apparent stress.<\/p>\n<\/p><\/div>\n

\n

1.4<\/span> This specification applies only to annealed glassware that is intended for sale as such. It excludes glassware that has been thermally tempered, ion-exchanged, or laminated with glass layers of differing expansion. The intent of this specification is to limit the residual stresses for safe consumer use in annealed glass, as it leaves the manufacturer.<\/p>\n<\/p><\/div>\n

\n

1.5<\/span> Stresses introduced by thermal expansion differences within the glassware are covered by this specification. Graded and glass-to-metal seals are excluded.<\/p>\n<\/p><\/div>\n
