1.1 This specification covers Type 101 sealing glass for use in electronic applications. Note 1: This specification is primarily intended to consider
glass as most generally used, this is, glass in its transparent
form as normally encountered in fabricating electronic devices.
X1.3 lists sealing metals and
alloys that are compatible with this glass. Type 101 glass in other
forms such as powdered, crushed, sintered, fibrous, etc. are
excluded. The requirements of this specification, as applied to
these forms, must be established in the raw glass prior to its
conversion.
1.2 This 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. |
