This may be a dumb question, but is there an industry standard used for FI specs?

For example, they all typically quote you a flow rate, such as 720cc per minute, but the actual flow rate achieved depends on the fuel pressure it is tested at. Is there an SAE or other industry standard that tells the OEMs what fuel pressure to test to and use for FI flow rate specs? I'm shopping around for FIs, and just want to understand this better.
