This document covers the monitoring of air cleanliness by particles in terms of concentration of airborne nanoscale particles.<\/p>\n

For monitoring purposes, only populations of particles with a lower size limit of 0.1 microns (100 nm) or less \u2013 \u201cnanoscale\u201d \u2013 are considered.<\/p>\n

The monitoring given in this document is for use mainly in \u201coperational\u201d states.<\/p>\n

\n

NOTE 1 For the purposes of this document, reference is made to \u201cnanoscale particles\u201d, which means all nano-objects having one (nanoplate), two (nanofibre) or three (nanoparticle) dimensions in the nanoscale.<\/p>\n<\/blockquote>\n

\n

NOTE 2 As a consequence, the specifications for monitoring air cleanliness by nanoscale particle concentration of the cleanroom in operational state also considers process specifics, e.g., used equipment, personnel behaviour, etc.<\/p>\n<\/blockquote>\n

\n

NOTE 3 Health and safety considerations are excluded from this document.<\/p>\n<\/blockquote>\n
