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.

C62.31-2020
IEEE Standard for Test Methods and Preferred Values for Low-Voltage Gas Discharge Tube Surge-Protective Components
This standard applies to low-voltage gas discharge tube (GDT ) surge-protective components for application on systems with voltages less than or equal to 1000 V rms or 1500 V dc. 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.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
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Superseded.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.
C62.31-2006
IEEE Standard Test Methods for Low-Voltage Gas-Tube Surge-Protective Device Components
This standard applies to gas-tube surge-protective devices for application on systems with voltages, 1000 V rms or 1200 V dc.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
C62.32-2004
IEEE Standard Test Methods for Low-Voltage Air Gap Surge-Protective Device Components (Excluding Valve and Expulsion Types)
This standard applies to air gaps for overvoltage protection applications on systems with operating voltages equal to or less than 600 V rms. This standard contains a series of standard tests for determining the electrical characteristics of these air gap devices. This standard's test criteria and definitions provide a common engineering language beneficial to users and manufacturers of air gap surge protective devices.
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
