What is BS 448-2 - Dimensions of electronic tubes about?
BS 448-2 is the second part of a multi-series standard used for Dimensions of electronic tubes and valves. This helps in designing and manufacturing good quality United Kingdom electronic tubes.
BS 448-2 covers such physical requirements of the bases, caps, and outlines of electronic tubes as are necessary to ensure mechanical compatibility and satisfactory electrical contact. Associated gauges and pin straightening tools are also covered. This standard deals only with electronic tubes registered in the United Kingdom and not covered in BS 448-1.
Owing to the many variables involved, including tolerances on pin diameters and permissible pitch circle eccentricity, it is not practical or economical to ensure complete compatibility in isolated cases where many component parts are on extreme opposing limits.
The standard is divided into four sections. Section 1 specifies general requirements for bases and
associated gauges and pin straightening tools. Sections 2, 3, and 4 contain data sheets specifying the dimensions of caps, bases, outlines, and associated gauges and pin straightening tools.
Note: Appendix A, Appendix B, and Appendix C identify which Part of BS 448 deals with which particular component.
Who is BS 448-2 - Dimensions of electronic tubes for?
BS 448-2 on Dimensions of electronic tubes is useful for:
- Manufacturer of electronic components
- Manufacturer of automotive parts
- Electronic engineer
Why should you use BS 448-2 - Dimensions of electronic tubes?
An electronic tube is a glass or metal enclosure in which electrons move through the vacuum or gas from one metal electrode to another.
BS 448-2 specifies the drawing and dimensions of electronic tube caps, line gauges for CRTs, and bases. This also helps in identifying the materials to be used in producing these electronic tubes. With the help of these dimensions, you can design and construct these tubes. By applying BS 448-2, you can standardize the manufacturing process which results in improving the quality of these United Kingdom electronic tubes.
