I don't think the factory posted a standard.
A good method is to watch the ejection pattern and distance.
When the ejected cases are going in other then the normal direction, or are going farther then normal, it's time to change.
However, since springs are cheap, you can just set your own schedule to whatever seems reasonable to you and taking into consideration how powerful the ammo you're shooting.

I totally agree. I've heard every 1-2 thousand rounds, but that seems way too often.

Armorers are told in the classes to replace recoil & mag springs on duty weapons either every 5 years or every 5K rounds fired, whichever occurs first.
Personally, when it comes to the compact models (3913/6906, etc), I like to replace mine a bit sooner. Somewhere around 2500-3K rounds fired.
Of course, I also switched from using issued 147gr loads (standard pressure) to using either 127gr +P+ or 124gr +P loads (both issued at different times) over the last several years. Higher pressure loads can easily accelerate the expected wear & tear, and the shorter/lighter slides used on the 3913/6906 compacts were run harder & faster with the higher pressure loads. Increased slide velocities not only put more stress on the recoil spring, but the mag springs have to work harder to keep up with the faster cycling slides (for proper feeding timing).
Factory recoil & mag springs are pretty inexpensive, all things considered.
Just my thoughts.
