Though FED-STD-209D was traditionally implemented, the issue of unit designation specific to the country persisted. Therefore, shifting to International System of units was adopted and global unified regulations [ISO 14644-1] were established for cleanliness factor.

Method similar to JIS system is followed with target particle size of 0.1μm, and target space of 1 cubic meter.
