Cleanliness Standards
The standards tables are reproductions of the targets for each of the international
standards supported by the Lasair II particle counter. The blank areas of the tables
represent invalid settings. For example, the ISO 14644-1 standard does not allow
certification of a class 1 cleanroom using a 0.3+ µm particle size.
ISO 14644-1 Standard
The document, ISO 14644-1 (1999-05-01), was used when designing the ISO
14644-1 module. Only the classes specified in the document’s tables have been
implemented; The Lasair II particle counter does not support intermediate class
sizes or intermediate particle sizes.
