| CE Marking | EU Declaration of Conformity, technical file summary, risk assessment, and applicable test reports | Exact model number, manufacturer or importer details, applicable EU legislation, harmonised standards, signature, and declaration date | Compare the declaration with the product label, user manual, electrical design, and test-report model numbers | 25% | Accept only when the documentation covers the exact ATV sound bar configuration. A CE mark alone is not sufficient evidence of conformity. |
| FCC Compliance | FCC test report, Supplier's Declaration of Conformity, or FCC equipment authorization records, depending on the product configuration | FCC ID when applicable, tested radio functions, operating frequencies, emissions limits, responsible party, and product model | Search the official FCC equipment authorization database when an FCC ID is provided; otherwise review the complete compliance file | 25% | Verify Bluetooth, Wi-Fi, or other intentional radiators separately from unintentional digital circuitry. The report must match the final antenna and power configuration. |
| RoHS | RoHS Declaration of Conformity, material declarations, supplier declarations, and representative material test reports | Coverage of restricted substances, homogeneous-material basis, component list, laboratory method, sample identification, and revision date | Check whether the evidence covers cables, solder, plastics, coatings, batteries, and electronic components—not only the finished housing | 20% | Request updated evidence after material, supplier, battery, or component changes. Generic statements without product scope should be treated as incomplete. |
| ISO 9001 | Current ISO 9001 certificate issued by an accredited certification body | Certificate number, legal entity, manufacturing site, scope, issue date, expiry date, and certification standard edition | Confirm the certificate through the certification body's public directory or direct written verification | 15% | The certificate should cover design, development, production, or relevant quality activities at the actual manufacturing site. |
| Product Safety Testing | Electrical safety, EMC, ingress protection, vibration, temperature, and battery-related test reports where applicable | Test standard, laboratory identity, accreditation status, sample description, test conditions, results, and deviations | Match the tested sample to the production bill of materials, enclosure, firmware, battery, charger, and wireless module | 10% | Give priority to reports from competent laboratories with clearly stated methods and traceable sample identification. |
| Documentation Control | Controlled product specification, revision history, change-control procedure, and compliance-maintenance plan | Document revision, approval authority, change notification process, retention period, and responsible compliance contact | Ask how the manufacturer handles PCB, antenna, battery, firmware, supplier, and enclosure changes after approval | 5% | Prefer suppliers that provide written change notifications and repeat testing when a change may affect compliance. |
