| Medical-device quality management system | ISO 13485:2016 | A documented quality system covering design, purchasing, production, process control, complaint handling, corrective action, and post-market activities. | Valid certificate, certification scope, issuing certification body, audit status, and site address. | The certificate must cover the actual manufacturing site and the relevant thermometer product category. |
| European market conformity | Regulation (EU) 2017/745, Medical Device Regulation | A conformity assessment appropriate to the device classification, intended purpose, labeling, clinical evaluation, risk management, and technical documentation. | EU Declaration of Conformity, technical documentation index, risk-management records, clinical evaluation, and, where required, Notified Body information. | Confirm that the CE documentation matches the exact model, intended use, manufacturer, and applicable MDR requirements. |
| United States market authorization | U.S. FDA medical-device requirements; applicable 510(k) pathway where required | A compliant establishment, device listing where applicable, and market authorization or exemption supported by the intended use and product classification. | FDA establishment registration and device listing details, 510(k) clearance number when applicable, labeling, and product identification. | Verify the FDA record directly and ensure the listed product is the same model and intended-use configuration being purchased. |
| Calibration traceability | ISO/IEC 17025; national metrology system and SI traceability principles | A controlled calibration process for reference instruments, production testers, and finished thermometers, with an unbroken measurement chain. | Calibration certificates showing equipment ID, measurement points, uncertainty, environmental conditions, due date, reference standards, and laboratory accreditation details. | Certificates should identify the tested instrument and demonstrate traceability to national or international measurement standards. |
| Temperature measurement performance | Applicable product specifications, risk controls, and recognized thermometer test methods | Defined accuracy, repeatability, response time, operating range, emissivity assumptions, and performance limits for the stated use. | Type-test reports, production inspection records, sample measurement data, and approved product specifications. | Compare measured results with the approved specification at multiple temperatures and under documented test conditions. |
| Production process control | ISO 13485:2016 quality-control and production-control requirements | Controlled assembly, sensor installation, firmware loading, functional testing, labeling, packaging, and release procedures. | Process flow chart, work instructions, inspection plans, lot records, operator training records, and final-release checklist. | Confirm that critical process steps are documented, operator qualifications are current, and nonconforming units are segregated. |
| Risk management | ISO 14971:2019 | Identification and control of risks related to inaccurate readings, incorrect use, software, battery operation, cleaning, and foreseeable misuse. | Risk-management plan, hazard analysis, risk-control verification, residual-risk evaluation, and benefit-risk assessment. | Check that identified risks are linked to design controls, verification results, labeling, and post-market feedback. |
| Electrical safety and EMC | Applicable IEC 60601-1 and IEC 60601-1-2 requirements for medical electrical equipment | Electrical safety and electromagnetic compatibility appropriate to the device design and intended clinical environment. | Test reports from a competent laboratory, test configuration, model identification, deviations, and final conclusions. | Ensure the reports cover the final hardware, firmware, accessories, power source, and intended-use configuration. |
| Software and firmware control | Software lifecycle and medical-device quality controls appropriate to product risk | Controlled development, version management, verification, cybersecurity consideration, change approval, and release identification. | Software version history, requirements, test records, change-control forms, and release documentation. | The firmware version used in production should match the version covered by verification and regulatory documentation. |
| Supplier and component control | ISO 13485 purchasing and supplier-control requirements | Approval and monitoring of suppliers for infrared sensors, electronics, batteries, plastics, packaging, and other critical components. | Approved supplier list, incoming inspection criteria, certificates of conformity, component specifications, and supplier audit records. | Verify lot identification, incoming inspection results, approved alternatives, and change-notification procedures. |
| Complaint handling and post-market surveillance | ISO 13485:2016 and applicable market-specific vigilance requirements | A documented method for recording complaints, investigating failures, assessing reportability, implementing corrective actions, and monitoring trends. | Complaint procedure, anonymized investigation examples, CAPA records, trend reports, recall procedure, and customer-feedback records. | Confirm that complaints are risk-assessed, investigated within defined timelines, and linked to corrective and preventive actions. |
