| Quality management system | Current quality manual or process map, internal audit records, management review minutes, and corrective-action records. | Confirm that documented processes cover purchasing, production, inspection, nonconforming products, and corrective action. Sample records should show issues were investigated and closed. | To be verified | Review a recent completed corrective action from detection through effectiveness check. |
| ISO 9001 certification | Certificate showing the legal entity, site address, certification scope, standard edition, issue date, expiry date, and certification body. | Verify certificate status directly with the certification body or its official directory. Confirm that the audited site and relevant manufacturing activities fall within the stated scope. Certification alone does not establish product compliance. | To be verified | Request the certificate and independently confirm its validity and scope. |
| Document and record control | Controlled procedures, revision history, inspection forms, and retained production and test records. | Check that employees use current document revisions and that records are legible, dated, attributable to an operator or inspector, and retrievable by product or batch. | To be verified | Trace one finished-product batch back to its inspection and production records. |
| Incoming-material inspection | Supplier specifications, incoming inspection reports, component identification, and nonconforming-material records. | Check how key components such as LED modules, power supplies, cables, connectors, and plastic housings are identified and inspected against documented requirements. | To be verified | Compare a recent incoming inspection record with the related component specification. |
| Production process controls | Work instructions, process parameters, operator training records, and in-process inspection results. | Confirm that assembly and wiring steps have clear instructions and that relevant checkpoints are recorded. Check how process changes and deviations are approved and documented. | To be verified | Observe a production operation and compare it with the current work instruction. |
| Final inspection and traceability | Finished-product inspection plans, pass/fail records, batch or serial identification, and release authorization. | Confirm that inspection criteria are defined before shipment and that sampled units can be linked to their production batch, inspection results, and release decision. | To be verified | Select a recent batch and trace its identification through final inspection and shipment release. |
| Electrical and functional testing | Test procedures and records for functions relevant to the product, such as power-on, dimming, color modes, controls, and charging where applicable. | Check that test conditions and acceptance criteria are documented, results are recorded, and failures are segregated and dispositioned. Confirm that the test setup matches the product configuration. | To be verified | Witness a test on a representative unit and compare the result with its recorded criteria. |
| Safety and market compliance | Applicable test reports, product specifications, declarations, and destination-market compliance documentation. | Confirm that standards and requirements are selected for the product type and destination market. Depending on the design and market, relevant standards may include IEC 60598, IEC 62471, or applicable EMC requirements. Check report model details and configuration against the product offered. | To be verified | Match the tested model, components, and report scope to the production model and target market. |
| Measurement equipment | Equipment inventory, calibration certificates, calibration status labels, and out-of-tolerance investigation records. | Check that instruments used for acceptance decisions are suitable for their purpose, within their calibration period, and traceable to recognized measurement standards where applicable. | To be verified | Choose a test instrument and verify its identification, calibration status, and latest certificate. |
| Nonconforming products and corrective action | Rejection logs, rework or scrap records, root-cause analyses, and corrective-action effectiveness checks. | Confirm that failed products are identified and controlled to prevent unintended shipment, and that recurring issues are analyzed rather than merely re-inspected. | To be verified | Review one recent quality issue and verify the documented containment and resolution. |
| Supplier and change control | Approved-supplier records, supplier evaluations, engineering change notices, and customer approvals where required. | Check how changes to components, materials, firmware, or manufacturing processes are reviewed for quality and compliance impact before implementation. | To be verified | Trace one component or process change from approval to updated production documentation. |
| Customer complaints and warranty feedback | Complaint logs, returns analysis, response records, and trend summaries. | Confirm that complaints are recorded, investigated, and linked to corrective action where appropriate. Check whether repeat issues and product-family trends are reviewed. | To be verified | Review a recent complaint and trace its investigation, response, and any resulting action. |
