The primary authority in the us and canada is the iso classification system iso 14644 1. An iso 1 is the cleanest whereas an iso 9 is the dirtiest status for cleanroom standards.

Iso 14644 1 and iso 14698. Cleanroom design and construction. Iso 14644 1 and iso 14698 are non governmental standards developed by the international organization for standardization iso. For instance class 7 cleanroom class 10 000 should contain no more than 2 930 ppm of particulates that are less than 5 microns in size or 352 000 ppm of particulates less than 0 5 microns per cubic meter of room area.

The former applies to clean rooms in general see table below. The ambient air outside in a typical city environment contains 35 000 000 particles per cubic meter 0 5 micron and larger in diameter corresponding to an iso 9 cleanroom which is at the lowest level of cleanroom standards. Ordinary room air is around class 1 000 000 or iso 9. Cleanroom testing for compliance.

To measure contaminants found in the cleanroom the standard deployed is a micron or micrometer μm micron measurement represents the cleanroom standard size for.
