1 flow between districts: in order to prove the direction of control flow between the districts is correct, it is from the clean area to the cleanliness of the regional flow difference must be detected: (1) the interval of the pressure difference is correct; (2) the door or wall floor at the opening of the flow direction is correct, namely region flow from the clean area to the clean degree of difference.

2 air supply and exhaust air volume: if it is turbulent clean room, then it is to measure the air supply and exhaust air volume. If the unidirectional cleanroom is to measure the wind speed.

3 filter leak detection: for the HEPA filter and an inspection, to ensure that the suspended pollutants will not go through: (1) damage to the filter; (2) the gap between the filter and the frame; (3) the other part of the filter device and into the room.

  4 isolation leak detection: this test is to prove that the suspended pollutants not through building materials into the clean room.

5 types of indoor air flow control: air flow control test according to the flow pattern of clean room is still unidirectional flow and turbulent flow. If the clean room for air turbulence, you must identify no indoor airflow runs insufficient area. If the unidirectional flow clean room, you must verify the indoor wind speed and wind direction is comply with the design requirements.

6 suspended particle concentration and the concentration of microorganisms: if these meet the requirement, the last of the particle concentration and the concentration of microorganisms (when necessary) were measured in order to verify its compliance with the technical conditions of cleanroom design.
