What is the tolerance for the starting voltage test in a motor?

[etienned]

Hello,

How can I find the tolerance for a synchronous motor in a dryer concerning the starting test voltage?
For the heating test the tolerance is +-10% of the nominal voltage.
But for the starting voltage ?

Thanks

Check IEEE Std 115 "Test procedure for Synchronous Machines" Part 7.1.3
