The ISO norm, the classes of categorization of Cleanrooms

The standards adapted to the cleanroom environment are NFS90-351 and ISO 14644. We find these requirements in a pharmaceutical laboratory for example.

The ISO classifies the levels of requirement, the classes:

The various materials used for the realization will have to take into account:

  • The elimination of all potential contamination by leaching

  • The durability in order to guarantee the environment throughout its use

  • The watertightness in order to respect the defined pressure cascades

  • The guarantee of the particulate level of each of the considered zones
