IEC 60139:2000 pdf free download.Preparation of outline drawings for cathode-ray tubes, their components,connections and gauges.

3.1.2.2

major axis

axis in the direction of the longer dimension of the CRT screen which passes through and is perpendicular to the principal axis, normally the horizontal axis

3.1.2.3

minor axis

axis along the shorter dimension of the CRT screen which passes through and is perpendicular to the principal axis, normally the

vertical axis

3.1.2.4

diagonal axis

axis connecting opposite corners of the CRT screen

3.1.3

band

hardware that surrounds the CRT panel and 1) holds the mounting lugs and implosion safety hardware to the CRT, 2) applies

compressive loads to the panel for mechanical safety and 3) contains the panel glass temporarily in the event of breakage

NOTE This band may be mechanically tensioned and joined at a lunction: it may be joined to the CRT with resin, or it may also be a single piece that is thermally shrunk over the panel (so called shrink-fit).

3.1.4

beam clearance

clearance between the electron beam path and the flare region of the funnel connecting the CRT neck to the body of the funnel.
