Clean room testing Let's take a look at the method and process.

       1. Clean room inspection manufacturers talk about clean room related concepts

The clean area is a closed space, and the concentration of particulate matter in the air is controlled. The construction and use of the clean area should reduce the interception, generation and retention of particulate matter in the space, and control the temperature, humidity, pressure and other related parameters in the space.

Air and cleanliness refer to the degree of dust particles in the air in the clean technology environment. The higher the dust concentration, the lower the cleanliness. The lower the dust concentration, the higher the cleanliness.

The specific level of air cleanliness is distinguished by the level of air cleanliness, which is expressed by the dust concentration in the air during the operating time.

Suspended nanoparticles refer to the particles of suspended matter in the air that are used in the classification of ambient air cleanliness to pass through solid and liquid particles in the size range of 0.15μm.

2. Clean room testing manufacturers say the classification of clean rooms

1. The clean room inspection manufacturer said that according to the cleanliness level, it is divided into 1, 2, 3, 4, 5, 6, 7, 8, and 9 respectively. Level 9 is the lower level.

2. The clean room inspection manufacturer said that the clean room can be divided into three types according to the air flow organization: unidirectional flow, laminar flow and clean room.

A flow of air with parallel streamlines and uniform cross-sectional velocity in a single direction. Unidirectional water flow perpendicular to the horizontal plane is unidirectional water flow parallel to the horizontal plane.

Different non-unidirectional flow cleanroom Any cleanroom that does not meet the definition of unidirectional flow. Mixed Flow Cleanroom: An airflow cleanroom that combines unidirectional and non-unidirectional flow.

3. The clean room testing manufacturer said that according to the classification of suspended particles in the air that require cost control, the clean room environment can be divided into China's industrial clean room and biological clean room.

Industrial clean room, its main control parameters are temperature, humidity, wind speed, air flow organization and cleanliness.

Biological clean rooms, like industrial clean rooms, differ in that the control parameters increase the concentration of bacteria in the control room.

4. The clean room testing manufacturers say that the test status of the clean room can be divided into three categories.

(1) The clean room inspection manufacturer said that all the pipelines in the well-equipped clean room are connected and operated without production equipment, materials and personnel.

(2) Clean room testing The manufacturer said that the static has been fully built and the production technology equipment has been installed in the clean room with complete facilities and construction, and the owner has carried out the test in the way agreed by the supplier as required, but there is no production management personnel on site .

(3) Clean room inspection The manufacturer states that the dynamic facilities are in the specified operating state, and there are specified personnel present, working in a specified way.
