ISO Standards that apply to cleanrooms include:
Some Common Factors - Cleanroom Design
Since cleanrooms have a significant impact on quality assurance and product integrity, various parameters need to be taken into consideration while designing them.
Along with the type of product being manufactured, cleanroom design needs to account for other factors such as temperature, relative humidity, air flow and air changes per hour, which is why the EMS or environmental monitoring system is considered the most important instrumentation within clean zones.
Along with HVAC systems and alarm monitoring systems, Magnehelic gauges and other differential pressure sensors are used to help keep these controlled environments sterile. These devices can help measure and control airflow, cleanliness of HEPA filters, proper static pressure between cleanrooms and adjoining spaces, and more.
Energy efficiency is another aspect of cleanroom design that companies need to consider. Properly calibrated pressure sensors help HVAC control systems maintain accurate positive pressure, with very low levels of pressure. This allows for conditioned air to be saved within the clean zone and fans to run less, thus saving energy.
