1. Scope | ||||||||||||||||||||||
1.1 This specification covers Type 58 borosilicate sealing glass for use in electronic applications. Note 1: This specification is primarily intended to consider
glass as most generally used, that is, glass in its transparent
form as normally encountered in fabricating electronic devices.
X1.3 refers to a sealing
alloy that is compatible with this glass. Type 58 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. |
