Description: Considers varistors for surge protective applications on systems with DC to 420 Hz frequency and voltages equal to or less than 1000 V RMS, or 1200 V DC. Definitions, service conditions and a series of test criteria for determining the electrical characteristics of these varistors are given. If the characteristics differ with the direction of conduction, then the tests determine characteristics for both polarities. The tests are intended as design tests as defined in ANSI/IEEE Std 100-1977 and provide a means of comparison among various surge-protective devices. This standard applies to such devices having a monotonic increase in voltage with increasing current flow.
