What is a cleanroom?
A cleanroom is a modular environment in which several factors are kept under control, including; relative humidity, temperature, differential pressure, airborne particulates, microbes, and air flow.
Regular cleanroom validations are a vital part of achieving cleanroom compliance prior to operation.
Additionally, further validation is required during operation to ensure that a cleanroom continues to meet its ISO Class parameters.
Vivid Air specialises in cleanroom validation for medical and laboratory facilities, and offers a complete range of performance tests and services including:
Measurement of airflow volume flow
Rate of air change calculation
Unidirectional airflow velocity measurement
HEPA filter integrity testing (DOP and Particle Count)
HEPA filter replacement
Room pressure measurement
Monitoring of non-viable airborne particulate
Airflow visualisation
Clean-up recovery test
Temperature and humidity monitoring
Uniformity mapping
Containment and induction leak test
Room recoveries
We have ISO 14644-3 certified cleanroom technicians equipped with the latest calibrated testing equipment to perform turnkey cleanroom validations.
Additionally, we stock a full range of Air filters from ASHRAE Grade G3 right up to H14 HEPA filters of all standard filter sizes – allowing us to conveniently replace filters during validations. Our services include air filter maintenance schedules to suit your individual needs.
Cleanroom Certification
Cleanrooms are validated to an essential class of cleanliness. The level of cleanliness required is driven by the environment’s specific requirements. Cleanroom classes are defined in ISO1464-1.
Methods for measurement and evaluation for Certification are specified in ISO14644-3 which calls out for the following tests.
Count test for airborne particle
Airflow test
Air pressure differential test
Filter leakage test
Flow visualisation test
Airflow direction test
Temperature test
Humidity test
Recovery test
Containment leak test
As mentioned, once a cleanroom is certified to a particular class these factors must be monitored to ensure that parameters do not drift or change, and that the environment is kept under control.
