ISO 14644-3: Test Methods

ISO 14644-3 specifies the test methods used to verify cleanroom performance — covering particle count testing, airflow velocity and volume measurement, pressure differential testing, filter installation leak testing, airflow visualisation, temperature and humidity measurement, and recovery testing.

What It Requires:

That all testing of your cleanroom performance is performed using the methods and instruments specified in this standard — ensuring that test results are comparable, reproducible, and recognised by regulatory authorities.
