Cleanroom Performance Testing

Cleanroom Performance Testing is the performance evaluation of a cleanroom by conducting a series of defined tests with prescribed procedures and reporting requirements. The tests performed include evaluation of the quantity and quality of air supplied, the air movement between and within cleanroom, the particle (and where necessary microbiological) counts in the cleanroom. These requirements are laid down in the standards such as ISO 14644-1 ‘Classification of air cleanliness’. The international test methods used to test the cleanrooms are published in ISO 14644-3 but national document such as the following are still used:
  • Recommended Practice IEST-RP-CC006:’Testing cleanrooms’, and
  • Recommended practice IEST-RP-CC034:’HEPA and ULPA filter leak tests’ that is published by the Institute of Environmental Sciences and Technology (IEST) in the USA.




We measure and record cleanroom conditions and resolving all non-conforming areas in new and existing facilities. Our range of performance testing include:
  • Air volume and velocity test
  • HEPA/ULPA filter leak test
  • Airborne particle count
  • Temperature & relative humidity test
  • Light intensity test
  • Room pressurization test
  • Air visualisation study
  • Microbial count
  • Local Exhaust Ventilation (LEV) test
  • Recovery test
  • Indoor Air Quality (IAQ) monitoring
  • Bioaerosol and swab test
  • Compressed air test
