The fields that make one usable: lot identifier matching the container, test date, method identification specific enough to reproduce, the result as a number, and the acceptance criterion stated separately from the result.

Coming back to the opening post, because the follow-up matters more than the original answer.

The distinction between release testing and characterisation is one industrial documents make and retail ones usually do not. It is the difference between "we tested every lot for this" and "we established this once".

Reporting rather than recommending, on batch date. What happened is above. Whether it should have is a different question and not one I am qualified to answer.

Everything in post #14 holds. The case it does not cover is the one I have.

Batch date is a good example of a question where the honest answer is boring and the interesting answers are unsupported. I would go with boring.
