cleanroom standards

Application of
ISO 14644-3

This full-day course will explore the practical application of the ISO 14644 series that a certification contractor would use to certify a clean space. The course will include an open forum discussing how to implement the standards, what may or may not work in different types of cleanroom environments, and primary equipment used. In particular, the course will provide an in-depth examination of test methods for characterizing the performance of cleanrooms, as outlined in ISO 14644 Cleanrooms and associated controlled environments—Part 3: Test methods. Performance tests are specified for two types of cleanrooms (unidirectional and non-unidirectional) in three occupancy states (as-built, at-rest, operational). Registration for this course includes a copy of ISO 14644-3. In a group cleanroom evaluation exercise, participants will apply principles learned to an example specification.

This part of ISO 14644 specifies test methods for designated classification of airborne particulate cleanliness and for characterizing the performance of cleanrooms and clean zones. Performance tests are specified for two types of cleanrooms and clean zones: those with unidirectional flow and those with non-unidirectional flow, in three possible occupancy states: as-built, at-rest and operational. The test methods recommend test apparatus and test procedures for determining performance parameters. Where the test method is affected by the type of cleanroom or clean zone, alternative procedures are suggested. For some of the tests, several different methods and apparatus are recommended to accommodate different end-use considerations. Alternative methods not included in this part of ISO 14644 may be used if based on agreement between customer and supplier. Alternative methods do not necessarily provide equivalent measurements. This part of ISO 14644 is not applicable to the measurement of products or of processes in cleanrooms or separative devices.
