- Blind rows record ID as [0.0] in source; omitted.
- PLATE FF thickness identical to PLATE thickness for every size; FF column omitted.
- BLIND FF thickness identical to BLIND thickness for every size; FF column omitted.
- Source has no values for: PCD, No. of holes, Hole dia, RF dia, RF height.
- Verified flag values are copied from the source: 'STD', 'STD~ID' or 'CHECK'. The source does not define them; 'STD~ID' presumably means standard dimensions with a derived/non-standard ID, and 'CHECK' rows were flagged for review.
- Size column is the NB taken from the source Key (e.g. 'NB150'); 'Size label in source' is the Size cell as typed.
- Source also holds a duplicate set under DimStd 'BS 10 TABLE E' (no rating); it was checked and is identical to these rows, so it is not repeated.
- PCD and bolting from web reference 'BS 10 BS 10 flanges — Table E' (verified); matched 19 of 22 sizes. Verify drilling before machining.
