One that comes to mind (specific to Programmable Controllers [ aka PLC's])
is EN 61131-2 (IEC 61131-2).
6.3.7.1.1 (table 47) requires (inter alia ) testing incoming power AC
frequency from 0.95 to 1.05 of the nominal.
(As you may expect, the requirement is that the EUT must function
"properly" both during and after the tests.)

Do any product standards actually set limits for immunity to supply
frequency variations?
