What are the standards for cleanliness in several areas of clean engineering?

Clean engineering is a basic supporting industry with a wide range of application industries. In the 21st century, it has applications in many industries such as medicine and health, electronic information, semiconductors, optoelectronics, and precision manufacturing. According to the industry's precision and dust-free requirements, the level difference is also large. .
The most common use of clean engineering for medical and health care is the operating room, which adopts the MAU+AHU system, and the acceptance criteria are static and dynamic acceptance temperature, humidity, and CFU.
The biological safety laboratory purification engineering control features, the engineering purification equipment selects independent oxygen supply system, biological safety isolation clothing, waste liquid, exhaust gas unified purification through the tightness test and post-treatment, using airtight isolators, negative pressure secondary barrier system to protect the human body Safety, and formulate complete biosafety laboratory purification management regulations.
The three goals of biopharmaceutical purification control are cleanliness. The airlock room is widely used with six standards to control the clean room without cross-contamination; CFU refers to the number of living bacteria in the clean room; the project needs to obtain national GMP certification; these three are completed The goal can be a qualified purification project.
The cleanliness of the optoelectronic industry directly affects the quality of electronic products. Usually, a primary air supply and a secondary air supply system are used, and a large number of FFU fan filters are used to purify the air layer by layer to meet various standards.
