Building a 100000 level purification workshop standard?
Standard 1 for a 100000 level purification workshop: The maximum allowable number of microorganisms shall not exceed 500 planktonic bacteria per cubic meter; The number of settling bacteria shall not exceed 10 per culture dish.
Microorganisms include bacteria, viruses, single-cell organisms, etc. The purification workshop project focuses on examining two indicators: planktonic bacteria and settling bacteria. When conducting sedimentation bacteria testing, special culture dishes must be used, with specific nutrients placed in each dish. After being left in the workshop for a period of time, the number of sedimentation bacteria in the air can be calculated based on the number of bacteria growing in the nutrients.
Standard 2 for a 100000 level purification workshop: pressure difference. The pressure difference between clean rooms of the same cleanliness level should be consistent. For adjacent clean rooms of different cleanliness levels, the pressure difference should be ≥ 5Pa, and between clean rooms and non clean rooms, it should be ≥ 10Pa. This is mainly to ensure that the air flows from the clean area to the non clean area and avoid airflow backflow.
Standard four for a 100000 level purification workshop: temperature and humidity. The temperature is generally controlled at 20-22 ℃ in winter; 24~26 ℃ in summer; Fluctuation ± 2 ℃. The humidity in the clean room is controlled between 30-50% in winter and 50-70% in summer. When there are no special requirements for temperature and humidity, it is advisable to wear clean work clothes without feeling comfortable. Suzhou Xiling Purification
