ISO 14644 Clean Room Classification – Pharmaceutical Updates
Classification of area are given in many guidelines but the base of all other guidelines is ISO-14644-1. As we know that there are 9 classes of clean rooms in ISO but in pharmaceuticals mostly ISO Class 5 to ISO Class 8 are used for 0.5 μm and 5.0 μm. ISO-14644-1 defines the maximum concentration of particles per class and per particle size.
