What is Magnetics' specification for out of roundness on a ferrite toroid?

Out of roundness is controlled by mandating that cores meet overall dimensional tolerances for O.D. and I.D. while keeping enough cross section to meet the specified AL. Refer to the Ferrite Design Manual for toroid physical dimension tolerances.
