Product Details

Each country in the world has its own specifications, but according to the Federal Standard (FS) 209E issued by the US federal government in 1992, cleanrooms can be classified into six levels. They are level 1, level 10, level 100, level 1000, level 10000, and level 100000, respectively. If the level of the clean room is only described by the number of dust particles, it can be assumed that the size of the dust particles is 0.5 μ m. For example, the maximum number of dust particles in level 1, level 10, and level 100 clean rooms is less than or equal to 1, 10, and 100, respectively. If the size of the dust particles is not 0.5 μ m, the level of the clean room should be represented by the number of levels in a specific dust particle size. For example, level 10 is at 0.2 μ m (with a dust particle size of 0.2 μ m or larger and a density of no more than 75 particles per cubic foot), and level 1 is at 0.1 μ m (with a dust particle size of 0.1 μ m or larger and a density of no more than 35 particles per cubic foot).

1. Detection of airflow velocity and uniformity, which is a prerequisite for other tests of cleanroom effectiveness. The purpose of this detection is to clarify the average airflow velocity and uniformity in the working area of a unidirectional cleanroom.

2. System or room air volume detection.

3. Indoor cleanliness testing. The detection of cleanliness is to determine the level of air cleanliness that can be achieved in a clean environment, and particle counters can be used for detection.

4. Detection of self purification time. By determining the self purification time, the ability to restore the original cleanliness of the cleanroom when contamination occurs is identified.

5. Airflow flow pattern detection.

6. Noise detection.

7. Detection of illuminance. The purpose of illuminance detection is to determine the illuminance level and uniformity of the cleanroom.

8. Vibration detection. The purpose of vibration detection is to determine the amplitude of vibration indicated in each cleanroom.

9. Temperature and humidity detection. The purpose of temperature and humidity detection is the ability to adjust temperature and humidity within certain limits. Its content includes detecting the supply air temperature of the clean room, detecting the air temperature of representative measuring points, detecting the air temperature at the center point of the clean room, detecting the air temperature at sensitive components, detecting the relative temperature of indoor air, and detecting the return air temperature.
