I think there is so much variance from landlord to landlord. It's fairly well regulated tho so if taking a look at the tenant/landlord laws in your state might give you some information.
We are landlords and do always thoroughly clean, paint, and steam clean the carpet between tenants. Not sure what "standard is" tho.
In your case I'd definitely do a walk through with management to see what they may charge you for so that you have the opportunity to resolve those should you desire.
