This standard describes methods of measurement, requirements and precautions applicable to several types of crossed-field amplifier tubes for both continuous wave and pulse operation. As there are many types of crossedfield amplifiers which can be operated under a variety of operating voltage and r.f. conditions, these requirements and precautions can be taken only as general guidance to be read in conjunction with the manufacturers' instructions for the particular tube being measured.

IEC 61643-312:2013 is applicable to gas discharge tubes (GDT) used for overvoltage protection in telecommunications, signalling and low-voltage power distribution networks with nominal system voltages up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c. They are defined as a gap, or several gaps with two or three metal electrodes hermetically sealed so that gas mixture and pressure are under control. They are designed to protect apparatus or personnel, or both, from high transient voltages. This standard provides information about the characteristics and circuit applications of GDTs having two or three electrodes. This standard does not specify requirements applicable to complete surge protective devices, nor does it specify total requirements for GDTs employed within electronic devices, where precise coordination between GDT performance and surge protective device withstand capability is highly critical. Keywords: gas discharge tubes (GDT), overvoltage protection in telecommunications, signalling and low-voltage power distribution networks, nominal system voltages up to 1 000 V (r.m.s.) a.c. and 1 500 V d.c.
