Clean Room Validation A

Our company accumulates years of testing experience, providing customers with multiple aspects of testing services based on SOP for clean room tests.

All our test instruments pass calibration by original manufacturers, performing periodical calibration followed with instrument calibration certificate to ensure conforming to individual accuracy.

Therefore, our company would provide a detailed test report after completion of tests, filing for customers and reserved for reference of long-term following-up and communication.

Sample Location and Number (Unidirectional Airflow)
  • Sample locations must be evenly distributed in the sampling area
  • Sample locations must conform to (a)or(b)

(a)SI unit : A/2.32 (m2)
  Englih unit : A/25(ft2)
  A refers to area of clean room, for class 1 ~ 100.

 

(b)SI unit : A*64(10m)0,5 (m2) M : if class 1000=M4.5>M=4.5
  English unit : A/(Nc)0.5 (ft2) Nc : if class 1000 Nc=1000
  A refers to area of clean room
  M and Nc are respectively class of clean room, for class 1000~100000. Result stands for
  number of measuring locations.
  Ps : There shall be at least two locations for each area.

Number of Samples Required
  • Each location shall be measured at least once.
  • There shall be at least five samples for each area (Area; Room).
