Scope

This document sets forth the technical requirements for monitoring the concentration of "nanoscale" particles with a particle size not exceeding 0.1 μm (100 nm).
The monitoring techniques specified in this document are primarily intended for "dynamic" applications.
Note 1: The "nanoscale particles" referred to in this document refer to all nanomaterials that have a nanoscale dimension in one dimension (nanosheets), two dimensions (nanofibers), or three dimensions (nanoparticles).
Note 2: Please note that the actual characteristics of particles in cleanrooms are determined by the source of the particles and their physical properties.
Note 3: This document does not consider health and safety issues.
