The 12-year limit brings skiing into line with international sports bodies such as FIFA and the International Olympic Committee.
Kasper’s 23 years as FIS president followed a 46-year run by another Swiss official, Marc Hodler. Kasper died in July five weeks after the election to replace him.
The FIS statutes approved on Friday also require a minimum of three women on the governing body’s council. There was just one woman on the 18-member committee before the June election, where former long-time secretary general Sarah Lewis was a candidate.
A vote to change the FIS name was narrowly defeated despite getting majority support.
A proposal to rebrand as the International Ski and Snowboard Federation fell short of a required two-thirds majority in a 66-49 vote.
