1. Temperature and humidity control: class 1,000 purification workshop needs to strictly control the temperature and humidity to ensure the quality of products and production efficiency in the production process. General requirements for the temperature at 22 ℃ ± 2 ℃, relative humidity at 55% ± 5%.
2. Cleanliness level: 1,000 clean room cleanliness level for ISO 8, that is, each cubic foot of air containing particles greater than or equal to 0.5 microns should be less than 350,000, greater than or equal to 5 microns should be less than 3000 particles.
3. Differential Pressure Control: Thousands of cleanroom need to maintain indoor and outdoor pressure difference, in order to prevent outdoor pollutants into the room. General requirements of the pressure difference of 5 Pascal or more.
4. Noise control: thousand purification workshop noise should be controlled within a certain range to ensure that the staff's physical and mental health and work efficiency. General requirements for noise below 70 decibels.
5. Illumination control: thousands of clean room illumination should be maintained within a certain range to ensure that staff can clearly see the production process and product conditions. General requirements for illumination in 400 lux or more.
6. Air disinfection: a thousand purification workshop needs regular air disinfection to kill bacteria, viruses and other microorganisms in the air, to ensure the quality of products in the production process and the physical and mental health of the staff.
7. Air filtration: a thousand clean room need to use high-efficiency filters for air filtration to remove particles, bacteria, viruses and other harmful substances in the air. Generally require the use of filters with an efficiency greater than 99.97%.
8. Equipment Requirements: Thousands of cleanroom equipment should meet the health requirements, easy to clean and maintain, and with measures to prevent contamination and cross-contamination.
9. Personnel management: thousands of purification workshop staff should be hygiene training, comply with health regulations, and wear clothing and protective equipment in line with health requirements.
10. Environmental hygiene: the environmental hygiene of the thousand-level purification workshop should be kept neat, clean, free of debris, no garbage, no stagnant water, etc., and regular cleaning and maintenance.
The above is the main content of the grade standard of the thousand-level purification workshop, these standards are to ensure the quality of the product in the production process and the key factors of production efficiency, but also to ensure the physical and mental health of the staff and the efficiency of the important factors.
