Hello Juan! The industry expectation for the solderability of a component is 1 year and the majority of component suppliers will provide components with a solderability guarantee for that time period. The 2 year time period you mentioned was an old MIL-STD-2000 clause that stated you could extend the 1 year solderability life by conducting a solderability test and if the component had acceptable test results, extend the solderability life the additional year.
