Clean workshop classification: How much do you know?

In modern industrial production, the classification of clean workshops is an important link to ensure product quality and production safety. The classification of clean workshops is not only related to the quality of products, but also to the safety and efficiency of the production process. So, how is the level of clean workshop divided?

Today, let’s uncover the mystery of the classification of clean workshops.

First, the basis for the classification of clean workshops
The classification of clean workshops is mainly based on the number and size of particles in the air. According to the international standard ISO 14644-1, the grade of clean workshop is divided into 0 to 9, of which 0 is the highest level and 9 is the lowest level. Each grade has its own specific requirements for the number and size of particles.

Second, the specific standards for the classification of clean workshops

1. Level 0: The number of particles in the air with 0.1 micron particles does not exceed 0.1 per cubic meter.
2. Level 1: The number of particles in the air with 0.1 micron particles does not exceed 1 / cubic meter.
3. Level 2: The number of particles in the air with 0.1 micron particles does not exceed 3.5 per cubic meter.
4. Level 3: The number of particles in the air with 0.1 micron particles does not exceed 7 per cubic meter.
5. Level 4: The number of particles in the air with 0.1 micron particles does not exceed 10 per cubic meter.
6. Level 5: The number of particles in the air with 0.1 micron particles does not exceed 100 per cubic meter.
7. Level 6: The number of particles in the air with 0.1 micron particles does not exceed 1000 / cubic meter.
8. Level 7: The number of particles in the air with 0.1 micron particles does not exceed 10,000 / cubic meter.
9. Level 8: The number of particles in the air with 0.1 micron particles does not exceed 100,000 per cubic meter.
10. Level 9: The number of particles in the air with 0.1 micron particles does not exceed 1,000,000 per cubic meter.

Third, the significance of the classification of clean workshops
The classification of clean workshops is of great significance to ensure product quality and production safety. Different levels of clean workshop, suitable for different production needs. For example, a Class 0 clean workshop is suitable for production environments where the number of particles is very high, such as semiconductor manufacturing, biopharmaceutical, and so on. The class 9 clean workshop is suitable for production environments with relatively low requirements for the number of particles, such as general manufacturing.

Fourth, precautions for the classification of clean workshops
In the classification process of clean workshops, the following points need to be noted:

1. Ensure the normal operation of the air filtration system in the clean workshop to ensure that the number and size of particles in the air meet the grade requirements.
2. Regularly inspect and maintain the clean workshop to ensure the accuracy of its classification.
3. In the clean workshop, the operating procedures should be strictly observed to prevent the generation and diffusion of particles.
