A presentation of the revised 2015 cleanroom standard iso 14644 parts 1 and 2. Measurement of viable materials iso 14698 testing cleanroom functionality iso 14644 4 and testing of separative devices iso 14644 7.

The most common classes are iso 7 and iso 8. What exactly is cleanroom classification. Iso 14644 consists of the following parts under the general title cleanrooms and associated controlled environments. Iso 14644 1 and older standard fs 209e determine class by the concentration levels of particles.

It also specifies the standard method of testing to determine cleanliness class including selection of sampling locations. Iso 14644 1 specifies classes of air cleanliness in terms of the number of particles expressed as a concentration in air volume. This standard applies in general to all cleanrooms. In addition other standards can be considered to be applicable.

Many factors besides airborne particulate cleanliness must be considered in the design specification operation and control of cleanrooms and other controlled environments. The presentation focuses on the key features for particle control and cleanroom classification. Simply speaking for iso 14644 1 classification threshold particles of 0 1 microns to 5 microns in size are considered. The committee responsible for this document is iso tc 209 cleanrooms and associated controlled environments.

This standard includes the cleanroom classes iso 1 iso 2 iso 3 iso 4 iso 5 iso 6 iso 7 iso 8 and iso 9 with iso 1 being the cleanest and iso 9 the dirtiest class but still cleaner than a regular room. The particles range in size from 1 5 microns µm. This part of iso 14644 is one of a series of standards concerned with cleanrooms and contamination control.
