What are the necessary items for daily inspection of clean room, and how long is the cycle?

Clean room needs to remove pollutants such as particulate matter, harmful air and bacteria in a certain range, and control indoor temperature, cleanliness, indoor pressure, airflow speed and distribution, noise and vibration, lighting and static electricity within a certain demand range. Generally, clean rooms are classified according to the number of particles in the laboratory air.

Clean rooms are classified according to air cleanliness. If only the number of dust particles is used to describe the grade of clean room, it can be assumed that the size of dust particles is 0.5μm, for example, the maximum number of dust particles in 1, 10 and 100 clean rooms is less than or equal to 1 and 10 respectively.

If the particle size of dust is not 0.5μm, the grade of clean room should be expressed as a series with specific particle size, which are 1, 10, 100, 1000, 10000 and 10000 respectively.

The required items include air supply (12 months), high efficiency filter leak detection (24 months), fresh air (12 months), exhaust air (12 months), static pressure difference (12 months), cleanliness and formaldehyde (24 months).
