Medical device manufacturers rely on controlled environments, calibrated equipment, and documented processes to protect product quality. Technical Safety Services (TSS) provides cleanroom testing and certification, environmental monitoring, equipment calibration, and qualification and validation support tailored to each facility, process, and quality system.
FDA's Quality Management System Regulation (QMSR), effective February 2, 2026, incorporates ISO 13485:2016 into 21 CFR Part 820. Where environmental conditions can affect product quality, manufacturers must establish and document appropriate controls. TSS performs testing to approved procedures and client-defined acceptance criteria, with traceable documentation provided by our 21 CFR Part 11-compliant electronic field collection software, eData.
Cleanroom Testing and Certification
Not every medical device process requires the same cleanroom classification or test package. TSS can classify air cleanliness under ISO 14644-1, support monitoring programs developed under ISO 14644-2, and apply relevant ISO 14644-3 test methods and IEST Recommended Practices.
Based on the approved scope, testing may include HEPA filter integrity; airflow volume, velocity, and room air change rates; differential pressure; temperature and relative humidity; nonviable particle classification and monitoring; recovery testing; and airflow visualization.
Microbiological Environmental Monitoring
For processes requiring microbiological control, TSS performs active air and surface sampling to evaluate bacterial and fungal recovery. Programs are based on process risk, facility classification, validation data, historical trends, and client-approved criteria. Deliverables can include laboratory analysis, quality-reviewed reports, and technical support for evaluating results and trends.
Nonviable Particle Counting
TSS performs nonviable particle counting for ISO 14644-1 classification and routine monitoring at client-defined intervals. Measurement instruments are calibrated with traceability to national or international standards, as applicable. eData supports direct capture or import of measurements, reducing manual transcription risk and providing traceable documentation. Project reporting can be tailored to routine certification, trending, investigations, or multisite programs.

Frequently Asked Questions
What environmental monitoring is required for medical device manufacturing?
No universal test list applies to every facility. Under the QMSR and ISO 13485:2016, manufacturers define environmental controls where conditions can affect product quality. Depending on the device and process, the monitoring plan may address particles, microorganisms, temperature, humidity, pressure, compressed gases, or surface cleanliness.
How often should environmental monitoring be performed?
Frequency should be based on process risk, cleanroom classification, validation data, historical trends, and applicable requirements. Monitoring may be continuous, periodic, or event driven. TSS can help define the schedule and provide recurring or targeted testing after excursions, maintenance, repairs, or process changes.
Do all medical device manufacturers need an ISO-classified cleanroom?
The appropriate environment and controls depend on the device and manufacturing process. When an ISO-classified cleanroom is used, classification and monitoring should follow the approved program and applicable ISO 14644 requirements.
Is third-party environmental monitoring required?
The manufacturer retains responsibility for controls, criteria, results, and corrective actions. TSS can provide calibrated instruments, trained personnel, standardized procedures, technical oversight, ISO/IEC 17025-accredited laboratory capabilities, and traceable documentation.
