Display & HMI Sample Acceptance Checklist
A display sample acceptance checklist helps procurement and engineering teams agree what a sample must demonstrate before the next build. Start with the approved configuration, then record each check, its method and the decision. A sample report applies to the identified sample and test conditions; it does not automatically validate every future unit.
1. Identify the sample and its baseline
Record the sample identifier, drawing revision, bill of materials and date. Identify the display, touch sensor, controller, keypad and enclosure configuration where these form part of the agreed assembly. Also record any customer-supplied components or temporary substitutes.
Compare this baseline with your display integration project brief. If a part or drawing changed during development, resolve the change before interpreting the results. Otherwise, a successful test may describe a different configuration from the one you intend to order.
2. Agree mechanical and appearance checks
Use the approved drawings to select the dimensions that matter for installation. These may include the panel opening, fixing positions, overall depth, connector access and clearance for cables. Record the nominal value, tolerance, measurement method and result for each selected feature.
Define viewing conditions for appearance checks as well. A statement such as “appearance OK” is more useful when both teams understand which surfaces, printing details and visible defects the check covers. Keep dimensional inspection and visual inspection as separate entries.
3. Check display, touch and keypad function
List the power supply, host equipment and interface used during the check. Then record the agreed display output and input checks. For touch, identify the areas and actions to test. For physical keys, use the agreed key map and record the expected response.
Include the intended gloves or surface conditions only when they belong to the agreed scope. Testing a bare finger on a dry screen does not establish wet-use or glove performance. Similarly, testing one interface does not prove that every optional connection works.
4. Separate environmental requests from evidence
If the project requires environmental checks, agree the profile, duration, powered state and acceptance criteria before testing. Storage conditions and operating conditions should have separate entries. For ingress protection, identify the installed boundary, mounting and seal covered by the test.
Distinguish three states in the checklist: requested, performed and supported by a report. A blank result or a “not applicable” entry is not a pass. Do not turn an intended requirement into a product claim without evidence for the relevant configuration.
5. Record deviations and the release decision
Give each open issue a reference, description, responsible person and next action. For example, a connector-access issue may require a drawing change and another fit check. Keep that action separate from checks the sample already passed.
Record whether the decision is acceptance, conditional acceptance or further work, using the categories agreed by both teams. Identify who made the decision and which records support it. Supplier inspection and customer approval are different decisions; keep both clear when both are required.
6. Connect the records to delivery
Agree the document list before release. Depending on the project, it may include the applicable drawing revision, inspection results, test records, identification and packing information. Specify what you actually need rather than assuming every document is part of every delivery.
Keep the sample identifier and revision references consistent across the records. Before the next build, resolve any changes that affect the accepted configuration. This makes the display sample acceptance checklist useful for the next decision, instead of leaving it as an isolated report.
Prepare the review with vanesen
Use the project brief checklist to organize the starting requirements. Review quality assurance and testing and delivery when defining the checks and records. Then contact vanesen with the sample scope and open questions.
This planning guide does not specify universal acceptance limits. Agree the inspection methods, numerical limits and deliverables for the actual project.
