There'should no real guideline for single speed chains. It's simply a question of economics. The chain will run and transmit power up to 3% stretch, which is 6 times the guideline for derailleur chains. At that point you'd replace the chain and sprockets together.
The concerns relating to derailleur systems don't apply to SS unless you're using a strong tensioner on the lower loop.
BTW - if you opt for a 3/32 chain, buy the widest one, ie. One for 6 or 7s, since wider chains are cheaper, and last longer, and you have no reason to go narrow.
