A large percentage of medical or pharmaceutical items are produced in clean rooms, in which the concentration of airborne particles is maintained at the required low level. EN ISO 14644 describes the requirements for clean rooms and associated cleanroom areas.
Different classifications are allocated to clean rooms according to the size and number of particles present (see graphic).
Medical components are mostly produced under air cleanliness Classes 8 and 7, meaning that zwicki-Line materials testing machines can be used directly in these production areas or in associated testing areas.
For more demanding cleanroom requirements such as those found in the pharmaceutical industry, Zwick can supply a specially adapted cleanroom edition of the zwicki-Line which may be used in clean rooms with Class 6 air cleanliness to DIN EN ISO 14644-1.
