What is the standard of dust-free workshop?

The standards for dust-free workshops usually include the following aspects:

1. air cleanliness: the air cleanliness of the dust-free workshop should reach a certain standard, that is, the content of pollutants such as particulate matter and microorganisms in the air should be controlled within a certain range. According to the requirements of different industries and products, air cleanliness can be divided into different grades, such as ISO 14644- 1, American Federal Standard 209E, etc.

2. Temperature and humidity: The temperature and humidity of the dust-free workshop should be controlled within a certain range to ensure the stability and suitability of the production environment. Generally, the temperature of clean workshop should be controlled between 20℃ and 26℃, and the relative humidity should be controlled between 40% and 60%.

3. Pressure and air exchange times: The dust-free workshop should be kept at positive pressure to prevent the outside polluted air from entering. At the same time, the ventilation frequency of clean workshop should reach a certain standard to ensure the freshness and purity of air.

4. Noise and vibration: The noise and vibration of the dust-free workshop should be controlled within a certain range to ensure the quiet and stable production environment.

5. Lighting and cleaning: The lighting in the dust-free workshop should be sufficient and uniform to provide a good visual environment. At the same time, the dust-free workshop should be cleaned regularly to ensure the hygiene and cleanliness of the production environment.

6. Management of personnel and articles: The access of personnel and articles should be strictly controlled in the dust-free workshop to prevent the entry of polluted air from the outside. At the same time, the equipment and materials in the dust-free workshop should also be strictly cleaned and managed.

In a word, the standard of clean workshop is a comprehensive embodiment of many aspects, which need to be considered and realized from many aspects such as air cleanliness, temperature and humidity, pressure and air exchange times, noise and vibration, lighting and cleaning, personnel and goods management. Only by meeting these standards can the production environment and product quality of clean workshop be guaranteed.
