This standard BS EN 60139:2001 Preparation of outline drawings for cathode-ray tubes, their components, connections and gauges is classified in these ICS categories:

• 31.100 Electronic tubes
• 01.100.25 Electrical and electronics engineering drawings

IEC 60139:2000 gives guidance on the preparation of outline drawings of cathode-ray tubes (CRTs), tube components, tube sub-assemblies and ancillary components with the object of encouraging the same practice when publications are prepared in different countries. These recommendations are contained in the specimen drawings, descriptive text and in the tables of required dimensions.
