Cleanroom classifications vary depending on the specific product being manufactured. These standards are implemented to control environmental factors, particularly particulate concentrations and microbial limits.
In food production, the required cleanliness level depends on the nature of the product and the manufacturer’s quality objectives. Among these, ISO Class 8 (equivalent to Class 100,000 under FS 209E) and ISO Class 7 (equivalent to Class 10,000 under FS 209E) are the most commonly utilized standards.
