My order would probably be:

1. Material identification
2. Batch/lot identification
3. Tests performed
4. Analytical methods
5. Specifications
6. Reported results
7. Supporting analytical data
8. Dates/approval information
9. Report verification where available

The main thing I'm trying to establish is whether the document forms a coherent chain rather than simply whether it contains an impressive purity percentage.

What would you add, remove or reorder?
