Iso 14644 1 Cleanroom Standards

The need for a single standard for cleanroom classification and testing was long felt.

Iso 14644 1 cleanroom standards.

Iso 14644 1 2015 does not provide for classification of particle populations that are outside the specified lower threshold particle size range 0 1 µm to 5 µm. Cleanroom users shall then look to iso 21501 as a method to meet cgmp eu gmp iso 14644 1 and other requirements. This change to the iso 14644 1 represents an. This standard applies in general to all cleanrooms.
