1.1This practice covers the preparation and testing of reference glass-metal butt seals of two general configurations, one applicable to determining stress in the glass and the other applicable to determining the degree of mismatch of thermal expansion (or contraction). Tests are in accordance with Test Method F218, Subsection 1.1.
1.2This practice applies to all glass and metal (or alloy) combinations normally sealed together in the production of electronic components. It should not be attempted with glass-metal combinations having widely divergent thermal expansion (or contraction) properties.
1.3This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
