Decades of testing expertise
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:
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.
Mini or Micro-Environment Performance testing is also conducted in a similar manner whereby these “Isolated” manufacturing environments are tested individually. Examples include: enclosed Packaging or Filling Environments or any type of process that may be isolated within a smaller enclosure located within a larger Cleanroom Facility.
