Comprehensive Performance Testing and Certification Strategies

One Source Environmental has an almost three-decade long history dedicated specifically to Cleanroom Performance Testing. During this time, we have successfully built a diverse list of clients that we service routinely through annual facility re-certifications and maintenance services.

Using a combination of applicable industry standards and client-specific requirements, we work with your Quality Assurance or Facilities group to develop and implement a strategy for Cleanroom certification or testing.

Not all Controlled Environments are alike. Performance Testing is customized based on Cleanroom size, classification or any number of variables specific to a given controlled environment and industry. Tests are conducted using state of the art, company owned instrumentation calibrated to manufacturers specifications.

Individual Tests Include:

  • Cleanroom Airborne Particle Count Testing (100 nanometers and above)
  • HEPA/UPLA Airflow Velocity & Volume Testing
  • Cleanroom Airflow Visualization Testing using Visible Vapor
  • HEPA/ULPA Filter Integrity Testing
  • Differential Pressurization Testing
  • Sound Testing (Octave Band Analysis)
  • Vibration Analysis
  • Light Level & Uniformity Testing
  • Cleanroom Recovery Testing
  • Floor & Wall system Conductivity Testing

Tailored for your environment

Customized Performance Testing and Detailed Reporting

Resultant data is presented in a comprehensive report tailored specifically for the testing being performed and Client requirements. Reports can be organized as desired by the Client and typically by test type depicting facility areas in AutoCAD. Related test narratives and summary discuss procedures used, test results and any non-conforming issues that may be discovered with corrective recommendations.


FAQs

Have questions? We can help!

Here are some answers to common questions about this service. Still have questions? Get in touch and let’s talk through them together.

We recommend performing filter bench testing upon receipt of new filters and prior to installation to document initial integrity and performance.

Testing filters before installation helps identify manufacturing or shipping damage early and provides documentation to support responsibility if issues arise later.

Yes. If filter damage, leaks, or performance issues are identified, OSE can support repair or replacement to restore proper operation.

After repair or replacement, equipment is tested under controlled conditions to confirm restored performance and integrity before returning to service.

Yes. OSE provides documented test results, asset labeling, and field reports to support compliance and maintenance tracking.

Expert Cleanroom Certification You Can Trust

OSE delivers exceptional expertise and on-site problem-solving, resulting in a balanced, high-performing certified cleanroom. Their leadership and professionalism make them a pleasure to work with.

  • One Source Environmental (OSE) has consistently delivered excellent results and is a standout talent in the Cleanroom Certification business.

    For example, during a Nano Tech Cleanroom project we were building, the team displayed technical expertise and impressive problem-solving skills, tackling challenges with confidence. The Fan Filter Units had a tight plenum space that varied, forcing them to balance the fan speeds through the control system. When they were finished, the result was a balanced, well-performing, certified cleanroom.
