What is ISO 4 Cleanroom Certified?

Cleanrooms are environments with controlled conditions that are critical when manufacturing electronics, pharmaceuticals, food, and medical-grade equipment.

Not all cleanrooms adhere to the same sanitation standards, and the cleanliness of these rooms is measured using a scale developed by the International Organization for Standardization (ISO). This scale, known as ISO 14644-1, classifies cleanrooms based on the number and size of airborne particles present per cubic meter of air.

The scale ranges from Class 1 to Class 9, with Class 1 being the cleanest. Each class represents specific particle count limits that ensure the level of contamination is kept within acceptable boundaries to avoid compromising sensitive operations.

What is ISO 4 Cleanroom Certified?

An ISO 4 cleanroom certification signifies that a room meets specific particle count requirements established under ISO 14644-1:2015 standards. Specifically, ISO 4 cleanrooms allow up to 10,000 particles sized ≥0.1 µm per cubic meter and do not permit any particles larger than 1 µm in size.

This rigorous standard means these environments are exceptionally clean but still offer slightly more flexibility compared to stricter classifications like ISO Class 1 or Class 2.

Obtaining ISO 4 certification involves adhering to stringent protocols and procedures designed to minimize contamination from all possible sources, making this certification highly valued in industries requiring high-level cleanliness.

ISO 4 cleanroom certification ensures a highly controlled environment with stringent particle limits, crucial for industries like pharmaceuticals and electronics.

Adhering to these standards minimizes contamination risks and upholds operational integrity, which is vital for maintaining high-quality, contamination-free production processes.
