Allow for what?

Salaam

I wonder if "allow for" in the last line of the following paragraph means allow for new designs to be produced or allow for new designs to be tested?

Thanks in advance for your help.

"Most important of all, batteries must be safe. All batteries have to pass strict safety standards before they can be used in homes, in vehicles, on airplanes, and so on. Batteries that leak can cause expensive damage. But the most serious risk is fire. It may be that the testing criteria will have to change to allow for new designs that constantly change."
