These protective components are designed to limit voltage surges on balanced or unbalanced communication circuits and on power circuits operating from dc to 420 Hz. This standard contains a series of standard test criteria for determining the electrical characteristics and ratings of gas discharge tube surge-protective components. The tests in this standard are intended as design tests as defined in the IEEE Standards Dictionary [B1] , and provide a means of comparison among various gas discharge tube surge-protective components. Gas discharge tubes are used to provide over-voltage protection in electrical circuits. When the breakdown voltage of the gas discharge tube is exceeded, the normal high-impedance state of the tube changes to a low-impedance state to allow the gas discharge tube to conduct the surge discharge current. After the tube conducts the surge discharge current, it interrupts the flow of power follow current and returns to its high-impedance state.
Existing Standards	Superseded C62.31-1987 - IEEE Standard Test Specification for Gas-Tube Surge Protective Devices Superseded. Gas-tube surge-protective devices for application on systems with voltages 1000 V rms or 1200 V dc are covered. These protective devices are designed to limit voltage surges on balanced or unbalanced communication circuits and on power circuits operating from dc to 420 Hz. Test criteria for determining the electrical characteristics of these devices are provided.
	Superseded C62.32-1981 - IEEE Standard Test Specifications for Low-Voltage Air Gap Surge-Protective Devices (Excluding Valve and Expulsion Type Devices) Air gaps for overvoltage protection applications on systems with operating voltages equal to or less than 600 V rms are covered. These protective devices are designed for limiting the voltages on balanced or unbalanced communication, power, and signaling circuits. A series of standard design tests for determining the electrical characteristics of these air gap devices is specified. The tests provide a means of comparison among various air gap surge-protective devices.
