Short answer: A manufacturing specification sheet states measurable facts about the product: what it is, what it is made of, its dimensions and allowed tolerances, finish and colour, tests and pass/fail limits, and how it is labeled and packed. Read it as the definition of what will be made, and attach it to the order so every item is checkable.
