BS 7603 is an Internation standard that discusses the determination of stresses in glass-to-glass sealings. BS 7603 describes the test method for determining the stresses which may occur after the sealing of two glasses by means of stress birefringence.
BS 7603 on the determination of stresses in glass-to-glass sealings is useful for:
The main failure reason is that there are stresses in the glass-to-glass joint which are generated during the cooling process of sealing.
In order for BS 7603 helps to verify the calculation results, the test method for determining the stresses is used to obtain the point of the most dangerous stress and the tensile strength for the sealed specimens.
BS 7603 provides the test method for the determination of stresses in glass-to-glass sealings that will help tight sealing of glass. Using specifications provided in BS 7603 you will be able to construct the vacuum tubes, electric discharge tubes, incandescent light bulbs, glass encapsulated semiconductor diodes, reed switches, and pressure-tight glass windows.
To lower the seal failure probability, the effects of material properties of glass-to-glass sealings on the stresses are analysed using the determine the stresses in glass-to-glass sealings in BS 7603. Overall BS 7603 has important implications for the optimization of seal configuration in glass-to-glass sealings and makes sealing easy.
