Standard Specification for Type 101 Sealing Glass
description

Abstract

This specification covers Type 101 sealing glass for use in electronic applications. The glass shall have a finish that ensures smooth, even surfaces and freedom from cracks, checks, bubbles, and other laws of a character detrimental to the strength or life of the component or device for which its use is intended. Different test methods shall be performed in order to determine the following properties of the sealing glass: softening point, annealing point, thermal expansion coefficient, contraction coefficient, and bead seal.

Scope

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.
