A sample approval is most useful when it records exactly what was approved. The next production order should reference the same drawing, material and acceptance requirements, with any changes clearly identified.

Set the purpose of the sample

Is the sample being checked for fit, dimensional compliance, finish or another requirement? Agree the intended checks before it is produced.

Record approval against a revision

Use a part number and drawing revision. Record any accepted deviation separately; avoid relying on an informal “looks good” message to define future production requirements.

Confirm the production scope

Before the production order, align quantity, material, finish, inspection, packaging, delivery and payment terms. An approved sample does not by itself confirm every commercial term.

Keep changes visible

If a drawing, material or process requirement changes, identify it before manufacture and agree whether another sample or review is required.

Make repeat orders clear

Reference the approved specification and previous order where useful, but reconfirm quantity, price, timing and any changed requirements. Keep revision control explicit.
