Introduces a classification of air cleanness and explains the principles of clean space control. Six classes of air cleanness are specified for the work zone of clean spaces under operational conditions. The Standard complements the specific requirements set out in other parts of the series.

This Standard sets out the principles of clean space control. Six classes of air cleanness are specified and guidelines are given for the selection of airflow patterns, control of temperature and humidity, regulation of air pressure, materials and construction techniques, as well as operating procedures. The clean spaces may be achieved in rooms, or in workstations or safety cabinets within a room.NOTES:1. The designs of cleanrooms illustrated in this Standard are typical of existing installations which consistently demonstrate satisfactory performance. However, the principle criterion for room design is the achievement of the desired class of air cleanness. Alternative designs, such as those of large dimensions or, those constructed to protect specialized equipment and processes but which attain the same level of air cleanness as specified in the Standard, are acceptable within the limits of AS 1386.2, AS 1386.3 or AS 1386.4, as applicable. The ultimate test of the performance of clean space systems is that components processed within the facilities they serve economically comply with the manufacturing standards imposed upon them.2. Specific requirements for laminar flow cleanrooms, non-laminar flow cleanrooms, and clean workstations are specified in AS 1386.2, AS 1386.3, AS 1386.4 and AS 1386.5. Similarly, AS 1386.6 and AS 1386.7 specify requirements for operation and inspection of cleanrooms and installation and use of workstations. Requirements for safety cabinets are specified in AS 2252.1, AS 2252.2, AS 2567, AS 2639 and AS 2647. Separate specifications and related documents cater for certain vital components, e.g. air filters.
