The equations in Appendix S allow for a "corrosion allowance", if specified by the purchaser.

For Section 3.6.1.1, the typical procedure is to determine the minimum thickness, then add the corrosion allowance. Then, if this value is less than the value in 3.6.1.1, the value from 3.6.1.1 is used instead.
