BS 448-1 is the first part of a multi-series standard used for dimensions of electronic tubes and valves that specifies the rules and drawings of these electronic tubes and valves. This helps in designing and manufacturing good-quality electronic tubes and valves.
BS 448-1 gives recommended practice for the preparation of drawings for inclusion in this Publication.
BS 448-1 on Dimensions of Electronic tubes and valves is useful for:
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 448-1 specifies the general rule for drawing these electronic tubes and valves. This also specifies the dimensions and outline drawings for these tubes and valves. With the help of these dimensions and drawings, you can identify the materials to be used in manufacturing these tubes and valves. By applying BS 448-1, you can design and manufacture good-quality electronic tubes and valves.
