The International Organization for Standardization (ISO) sets worldwide cleanroom classification levels and standards. The ISO classification system defines cleanroom classes from ISO 1 to ISO 9, with ISO 1 being the cleanest and ISO 9 the least clean.
The primary authority in the US and Canada for clean room classification is the ISO classification system ISO 14644-1. Clean rooms are classified according to the cleanliness level of the air inside the controlled environment.
When converted to ISO standards, a Class 10,000 clean room (is similar to an ISO 7 cleanroom). Class 10,000 cleanrooms are one of the most common, if not the most common, level of cleanliness across the industry.
The ISO equivalent of a 100K cleanroom is an ISO 8.
An ISO Class 9 cleanroom is the least controlled environment among the ISO cleanroom classifications. While not as strictly controlled as cleaner classifications, these environments still aim to minimize contamination within defined limits.
An ISO Class 8 cleanroom maintains a controlled level of cleanliness at a maximum of 35,200,000 particles per cubic meter at sizes of 0.5 microns or larger.
