Cleanrooms and associated controlled environments are critical for industries where contamination can compromise product quality, safety, and functionality. From pharmaceutical manufacturing to semiconductor fabrication, maintaining strict cleanliness levels is mandatory. provides the essential testing methods used to measure, verify, and validate that these environments are operating within their specified standards.

ISO 14644-3:2019 is a standard that specifies the requirements for the testing and certification of cleanrooms and associated controlled environments. The standard is part of the ISO 14644 series, which provides a framework for the design, construction, and operation of cleanrooms and controlled environments. The standard was published in 2019 and replaces the previous version, ISO 14644-3:2006.
