" This standard establishes methods for testing and measuring the performance charac-teristics for surge-protective devices used in low-voltage ac power circuits. Definitions are statedthat apply specifically to surge-protective devices. The testing requirements are categorized intotwo groups, in which a minimum set of basic tests (BTs) are prescribed for all surge-protectivedevices within the scope of its documents, supplemented by additional tests (ATs) that might beneeded to establish particular application requirements. "

Establish performance characteristics for surge protective devices connected to low-voltage AC power circuits. Develop and recommend standard methods for testing and rating surge protective devices.

Recommend standard methods for test specifications and ratings for low voltage AC surge protective devices.
