Injection Pen OEM Sample Acceptance Checklist

How should an injection pen sample be evaluated?

Start by agreeing what the sample is intended to demonstrate and which decision it will support. Identify the configuration, acceptance criteria and unresolved evidence before the sample review begins.

A commercial appearance sample may support a color or packaging decision without establishing delivery performance. An engineering sample needs the relevant test purpose and controlled references. Record who will inspect the sample, which facilities or methods apply and who may approve the result. Ask the supplier to identify differences between the sample and the proposed production configuration. Do not infer clinical suitability from a polished housing or an attractive demonstration. Where a test depends on the formulation or primary container, assign those inputs to the responsible project team. The six-step checklist below turns the review into a traceable purchasing record rather than a general statement that the sample looks acceptable.

What must be recorded before approving the next stage?

Record the result against each acceptance criterion, the sample and drawing references, deviations and the named approver. State explicitly which decisions remain open and which next stage has been authorized.

A signature without a defined acceptance scope can create disagreement about tooling, performance or production readiness. Attach the relevant photographs and reports to their configuration record rather than treating every product-family image as one specification. If a drawing changes after the review, determine whether another sample or test is required. Keep cosmetic approval separate from compatibility, verification and market-responsibility records. Ask how rejected samples or nonconformities will be handled and when a revised submission is expected. A useful acceptance note identifies the decision date, the evidence reviewed and the limitations of the decision. The same discipline applies when a sample is accepted with conditions rather than approved without unresolved items.

What are the six steps in the sample acceptance checklist?

Define the purpose, identify the baseline, agree criteria, review the evidence, resolve deviations and record the scoped decision. Complete the steps for the identified sample and preserve open items before authorizing the next stage.

1. Define the sample purpose

   State whether the review concerns appearance, handling, engineering investigation or another defined stage. Record the decision that the sample is expected to support and the person responsible for it.

2. Identify the configuration baseline

   Record the product reference, sample identifier, device and container revisions, accessories, packaging and any differences from the intended production configuration. Keep separate source configurations in separate records.

3. Agree acceptance criteria

   Write measurable criteria and the evidence needed for each intended claim before testing. Assign owners for missing inputs and distinguish visual inspection from performance verification.

4. Review the sample and evidence

   Perform the agreed review using the identified sample and applicable methods. Record actual results, limitations and deviations; retain reports and photographs with their configuration references.

5. Resolve deviations and open items

   Assign a responsible person and a decision for every nonconformity or unknown. Determine whether a change requires another sample, revised drawing or additional evidence before the next stage.

6. Record the scoped acceptance decision

   Name the approver, evidence references, decision date, conditions and authorized next stage. Appearance acceptance does not by itself authorize clinical use or production release.

What else should the buyer confirm?

Confirm the scope of the proposed purchase and the evidence supporting the exact configuration. The answers below distinguish procurement decisions from assumptions that still require written confirmation.
