 A clean laboratory testing standards. Air supply and exhaust volume: If turbulence clean room, then they would have to measure the air supply and exhaust volume. If it is a one-way flow clean room, will have to measure the wind speed. 2. Flow control between districts: To prove correct direction of air movement between districts, that is, from clean areas to regional flow of poor cleanliness must be detected: (1) the correct pressure for each region; (2) at the door or wall the direction of the floor, etc. The opening of air movement is correct, that is, from clean areas to regional flow of poor cleanliness. 3. Filter Leak: The high efficiency filter and frame must be tested to ensure that the suspension of contaminants does not pass through: (1) damage to the filter; (2) the gap between the filter and its frame; (3 ) other parts of the filter device invading interior. 4. Isolation leak: This test is to prove that the suspension of contaminants does not invade through the clean room supplies. 5. Indoor air control: flow control type to be tested in accordance with cleanroom airflow patterns - is a one-way flow or turbulence may be. If cleanroom airflow turbulence, you must verify that run out of the room without air flow area. If the unidirectional flow clean room laboratory equipment, you must verify that the entire interior of the wind speed and direction is consistent with the design requirements. 6. Concentration of suspended particulates and microbial concentration: if these tests meet the requirements, the final particle concentration and the concentration of microorganisms (if necessary) measurements, in order to verify its compliance with the technical conditions of clean room design. Chemical processing and analysis of the chemical laboratory, a US credit protection precautions in the chemical analysis of the sample chamber measuring biological laboratory work often use some small electrical equipment and a variety of chemical reagents, such as careless operation also has a certain degree of risk. In chemical analysis room design should pay attention: laboratory building should be built with non-combustible or fire-resistant materials, partitions and ceiling fire resistance should take into account. Can terrazzo floors, windows to be able to dust physics and chemistry laboratories, indoor lighting is better. Doors should open outwards, large laboratories should be located two exits to facilitate evacuation of personnel in case of accidents.
