At this point, you need answers to some basic questions:

1. How Do I Know Which Classification I Need?

The specific requirements for your facility are determined to some degree by your industry and the state where your facility is located. Other factors that affect classification include

> Size of particles
> Number of particles
> Sources of potential contamination
> Appropriate air change rate

You can get classification information from government agencies, online resources, and industry leaders.

2. How Often Do I Need To Arrange Testing And Inspections?

According to standards set by the International Organization for Standardization, you should test every 12 months for all classifications. Particle count testing intervals are determined by ISO classifications. Some tests, such as filter leakage, airflow visualization, and recovery, are required every 24 months. Inspections may take place at the same time as cleanroom certification ca testing. If this is the case, they’ll occur at intervals of six or 12 months.

3. What Do Different Classifications Mean?

Classification levels are often established through testing. Cleanrooms receive classification according to the cleanliness of the air in the area. This is determined by a count of and size of particles per air volume. A classification of ISO 1 is given to the cleanest rooms, and an ISO 9 is the least clean. (It should be noted that even an ISO 9 classification is still much cleaner than an average room.

4. How Can I Improve My Classification Rating?

> Updated equipment
> Improved air filters
> Installation of cleansing systems
> Involvement of professionals
