Humidity stepping strengthening test method and system for intelligent electric energy meter

The invention provides a humidity stepping strengthening test method and system for an intelligent electric energy meter, and belongs to the technical field of reliability tests. The method comprisesthe steps of determining a humidity range used for carrying out a strengthening test on the to-be-tested intelligent electric energy meter; 1.1, carrying out a pre-test on the to-be-tested intelligentelectric energy meter in a test box, and determining an initial value of each parameter in a plurality of parameters; 1.2, determining that the to-be-tested intelligent electric energy meter within apredetermined time, carrying out the strengthening test on the to-be-tested intelligent electric energy meter for 1.5h according to test items, and obtaining a current value of each parameter; and 1.3, judging whether a difference value between the current value and the initial value of any parameter meets a stop criterion or not, and when the stop criterion is not met, RH is less than 85% and RHis equal to RH + 10% or RH
