After the completion of the clean room project, the project manager will carry out a preliminary acceptance test. The items that often need to be tested are wind speed, ventilation times, humidity, temperature, pressure difference and so on. After preliminary detection is qualified, next, request construction unit to give completion check and accept.

What are the procedures for clean room engineering acceptance? Clean room project completion acceptance shall be responsible for the design, construction organization, supervision by the construction unit. The function acceptance shall be carried out by the construction unit after the completion of the completion acceptance, and the design and testing shall be carried out by a third party with corresponding testing qualification, with the cooperation of the construction unit. After the completion of the functional acceptance, the construction unit shall be responsible for the use and acceptance, and the third party or the construction unit and the third party shall jointly conduct the test. Design, construction units to cooperate. The use acceptance is mainly to repeat some tests in the functional acceptance to determine its consistency with the use conditions.

According to the detection state, the acceptance of clean room engineering can be divided into empty state, static state and dynamic state. The inspection at the completion acceptance stage should be carried out in the empty state or static state, which should be determined by the negotiation of the builder, the designer and the construction party. It is generally carried out in the empty state. The inspection at the function acceptance stage should be carried out under static condition.

I. Empty acceptance (IQ)

The facility has been built, all power is connected and running, but there is no production equipment, materials and personnel

Test items: the complete set of clean room equipment, installation quality, pressure difference, airflow characteristics, surface cleanliness, sealing of maintenance structure, etc.

II. Static Acceptance (OQ)

The facility has been built, the production equipment has been installed and is operational, but no production personnel

Test items: whether the clean area division meets the requirements; Determine the parameters of self-cleaning time; Determine the stability of temperature and humidity; Determine the cleanliness level according to the number of particles; Determine the pressure difference; Determine illumination; Determine the noise level; Visually check the airflow and check the ventilation rate.

III. Dynamic Acceptance (PQ)

The facility has been operated in the prescribed condition, with the prescribed personnel present, and in the agreed condition

Test items: Verify clean room division system; Assess the ability to maintain temperature and relative humidity within prescribed limits; Verify differential pressure; Check the completeness of clean room operation documents; Check if the personnel are trained.

The acceptance test items of clean operating room and clean workshop are roughly the same. Clean workshop tends to pay more attention to the number of dust particles, while clean operating room pays more attention to the number of bacteria.
