There are altogether 13 types of test, as listed by the IES-RP-CC006.2 [4]. These further categories into 3 groups as follows:

Primary Test

• Airflow Volume, Velocity and Uniformity Tests:
  These tests are performed to determined the average of airflow velocity or uniformity within a cleanroom, cleanzone as well as determine air supply volume flow rate or uniformity.
• Filter Installation Leak Test:
  These tests are performed to confirm that the filter system is properly install by verifying the absence of bypass leakage in the installation and filters media are free of defects and small leaks. And it has two methods to proceed this test. One is Air generated aerosol challenge and aerosol photometer filter scan test method, the other is Alternative source aerosol particle challenge and discrete particle counter filter scan test.
• Particle Count Test:
  This test is performed to determine the completed as built, at rest or operating facility can meet the Fed-Std-209 air cleanliness class.
• Room Pressurisation Test:
  This test is to verify the capability of the cleanroom system to maintain the specified pressure differential between the cleanroom and its surroundings.

• Airflow Parallelism Test:
  This test is to verify the parallelism of airflow throughout the workzone and whether the cleanroom is capable of limiting the dispersion of internally generated contamination.
• Enclosure Integrity Test:
  This test is performed to determine if there is intrusion of unfiltered air into the cleanroom work areas from outside the cleanroom enclosure throughout joints, seams and doorways.
• Recovery Test:
  This test is performed to determine whether the cleanroom is capable of returning to its specified cleanliness class within a defined time after exposed to a source of airborne particulate challenge.
• Particle Fallout Count:
  This test is performed to determine the concentration of large airborne particle that are not detected effectively using discrete particle counter.
  

• Lighting Level & Uniformity Test:
  This test is to verify the specified lighting level or uniformity within a room.
• Noise Level Test:
  This test is to measure the airborne sound pressure levels produced by basic cleanroom mechanical and electrical system within the room
• Temperature & Relative Humidity Test:
  This test is to demonstrate the capability of the cleanroom’s AHU system to maintain the air temperature & relative humidity level over a period of time.
• Vibration Test:
  This test is to determine the vibration level on the cleanroom structure and components.
• ESD Floor & Wall Conductivity Test:
  This test is to measure the ESD situation in the Cleanroom Flooring or Partitions
