In the edition, the material properties are no longer in a separate annex, but are instead moved to the assessment part where they are mostly referenced. In a Level 1 assessment, surface damage, quantified by the pitted area and pit depth, is compared to standard pit charts to determine acceptability.

Another example is the previous Annex B1, which contained the procedures for demonstrating protection against various failure modes using stress analysis, which is now under Part 2 in Annex 2D. The complete list of limitations in Parts 2 and 6 of API should be reviewed before proceeding with a Level 1 pitting assessment.
