This standard applies to gas-tube surge-protective devices for application on systemswith voltages, 1000 V rms or 1200 V dc.

This standard applies to gas-tube surge-protective device components for application on systems with voltages less than or equal to 1000 V rms or 1200 V dc. These protective devices are designed to limit voltage surges on balanced or unbalanced communication circuits and on power circuits operating from direct current (dc) to 420 Hz. This standard contains a series of standard test criteria for determining the electrical characteristics of gas-tube surge-protective devices. The tests in this standard are intended as design tests as defined in The Authoritative Dictionary of IEEE Standard Terms [B1]1 and provide a means of comparison among various gas-tube su...

The purpose for the revision is to integrate comments made by members of the balloting group during the reaffirmation ballot in 1997. These changes will be limited to some editorial corrections and some technical updates limited to paragraphs 4.1, 4.7, 4.17, additions to Table 1 on page 14 and an additional definition for balanced voltage. Additionally, it is the purpose to harmonize with relevant IEC documents and later IEEE documents to change the title from "Standard test Specification" to "Standard Test Method" and add the word "Components" after Surge-Protective Devices to read: IEEE Standard Test Methods for Gas-Tube Surge-Protective Device Components....
