This standard applies to surge-protective devices intended to be installed on the load side of the main service disconnect packaged to be connected to 50 Hz or 60 Hz ac power circuits rated at 1000 V (rms) or less. Performance characteristics and standard methods for testing and rating are established for these devices@ which may be composed of any combination of components. The tests in this standard are aimed at providing comparisons among the variety of surge-protective devices available. Many of the tests described in this standard may stress a surge-protective device. Care should be taken to ensure that stressed devices are not compared with unstressed devices unless that is the desired intent. The suppression characteristics of some surge-protective devices change with successive surging as well as with changes in the environment. These changes may be permanent in nature. Selection and careful organization of appropriate tests can reduce the quantity of test samples needed. The voltage and energy levels employed in the majority of the tests described in this standard are hazardous and appropriate cautions must be exercised in their performance. Purpose The purpose of this standard is to provide users@ independent laboratories@ and manufacturers with test methods and test specifications applicable to low-voltage surge-protective devices@ intended for limiting transient overvoltages that can appear on ac power circuits of 1000 V (rms) or less.
