新IEEE标准-已被取代。 适用于直流频率为420 Hz、电压等于或小于1000 V rms或1200 V dc的系统上的浪涌保护应用的压敏电阻。提供了确定压敏电阻器电气特性的定义、使用条件和一系列试验标准。这些试验旨在作为设计试验，并提供一种比较各种浪涌保护装置的方法。

This standard applies to 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. This standard contains definitions, service conditions and a series of test criteria for determining the electrical characteristics of these varistors. If the characteristics differ with the direction of conduction, then the tests determine characteristics for both polarities. Arresters covered by ANSI/IEEE C62.1-1984 [1] are excluded from this standard.
