What is an ISO Class 7 Cleanroom1

What is an ISO Class 7 ?

Cleanrooms are highly controlled environments used in a variety of industries, including medical device manufacturing, pharmaceuticals, electronics, and aerospace. These cleanrooms must be designed and maintained to meet specific cleanliness standards to limit the presence of contaminants.

ISO (International Organization for Standardization) Class 7 cleanrooms are one of the most common types of cleanrooms used in manufacturing processes. Let's take a closer look at what they are, their classifications, and their applications.

What is a ?

A pharma clean room is a controlled environment in which the amount and type of airborne particulates are regulated to meet specific cleanliness standards. These particulates can include dust, microorganisms, and other contaminants that could affect the quality of the products being manufactured.

Standards

Cleanrooms are classified according to the number and size of particles per cubic meter of air. ISO standards are one of the most widely recognized and used standards for cleanroom classifications.

ISO Class 7

An ISO Class 7 cleanroom allows no more than 352,000 particles per cubic meter of air that are 0.5 microns or larger. This level of cleanliness is suitable for applications in which the products require a low level of environmental contaminants, such as aerospace and medical device manufacturing.

Designing and Maintaining an ISO Class 7

Designing and maintaining an ISO Class 7 cleanroom requires a comprehensive system that includes proper temperature control, humidity control, filtration, and ventilation. The system must also include procedures for cleaning and disinfecting the room and the equipment used within it to prevent contamination from occurring.

Temperature and Humidity Control

Temperature and humidity control are crucial aspects of cleanroom design. Control systems are utilized to keep the environment within a designated temperature and humidity range. This is necessary to prevent the growth of microorganisms, which can cause contamination.

Filtration and Ventilation

Filtration and ventilation systems are used to control the number and size of particles within the cleanroom environment. These systems use HEPA (High-Efficiency Particulate Air) filters to remove particulates from the air. This ensures that the environment remains within the specified cleanliness levels.

Cleaning and Disinfecting

Cleaning and disinfecting are critical processes in maintaining a cleanroom environment. Procedures must be in place to ensure that all surfaces, pharma machinery, and tools are cleaned and disinfected thoroughly before and after each use. This will prevent contamination from occurring and ensure that the ISO Class 7 standards are met.

Applications of an ISO Class 7

ISO Class 7 cleanrooms are used in various industries, including medical device manufacturing, aerospace, and electronics.

Medical Device Manufacturing

Medical device manufacturing requires a high level of cleanliness to ensure that devices are sterilized before use. An ISO Class 7 cleanroom is necessary to control the number and size of airborne particulates and microorganisms in the environment.

Aerospace

The aerospace industry requires a cleanroom environment to prevent contamination of components during assembly. An ISO Class 7 cleanroom is ideal for this application as it will maintain the required cleanliness levels.

Electronics

Electronics manufacturing also requires a clean environment to prevent contamination that could affect the performance of electronic components. An ISO Class 7 pharma clean room is necessary to ensure that the products meet the required standards.

Conclusion

ISO Class 7 cleanrooms are controlled environments designed to meet specific standards for cleanliness. These cleanrooms are used in a variety of industries where the presence of airborne contaminants could affect the quality of the products being manufactured. Proper design and maintenance of an ISO Class 7 cleanroom is necessary to prevent contamination from occurring and to ensure that the room meets the established cleanliness levels.
