IEC/TC 39 - IEC_TC_39

Applicable to cathode ray tubes and cathode ray tube assemblies which are intended for use as components in apparatus and which have integral protection with respect to the effects of implosion. A CRT covered by this standard is intended to be installed in an enclosure designed both to protect the rear of the CRT against mechanical or other damage under normal conditions of operation and to protect the user against particles expelled in a backwards direction from the CRT face in the event of implosion.

Gives guidance on the preparation of outline drawings of cathode ray tubes with the object of encouraging the same practice when publications are prepared in different countries.

Gives dimensions and tolerances for electronic tube and valve bases, holders and caps, together with the relevant gauges and gauging procedure, to ensure interchangeability. Also includes recommended practice for the preparation of drawings of electronic tubes and valves. This is a loose-leaf publication and supplements, containing new or revised sheets, are issued from time to time.

Applies to multi-electrode tubes, with the exception of cathode-ray tubes. Describes the system used for numbering the electrodes of the same type multi-electrode tubes and for assigning designations to the units of multiple-unit tubes.

Applies to the measurement of the direct interelectrode capacitances of electronic tubes of the following types: receiving tubes, cathode-ray tubes, gas tube and gas-filled valves, phototubes, photocells and multiplier types, high-power vacuum tubes.

This document applies to image converter and image intensifier tubes of assessed quality.
