Cleanrooms and associated controlled environments. Part 17: Particle deposition rate applications (ISO 14644-17:2021)

Alkalmazási terület

This document gives direction on the interpretation and application of the results of the measurement of particle deposition rate on one or more vulnerable surfaces in a cleanroom as part of a contamination control programme. It provides some instructions on how to influence the particle deposition rate and reduce the risk of particle contamination on vulnerable surfaces. This document gives information on how a cleanroom user can use the particle deposition rate measurements to determine limits that can be set for macroparticles on vulnerable surfaces. It also gives a risk assessment method by which an acceptable risk of deposition of particles onto vulnerable surfaces in a cleanroom can be established and, when this is not achieved, methods that can be used to reduce the particle deposition rate. An alternative to the particle deposition rate is the particle obscuration rate which determines the rate of increase of coverage of particles onto an area of surface over time. The particle obscuration rate can be used in an analogous way to the particle deposition rate and the required particle obscuration rate for a specified surface can be calculated and the risk from deposited particles reduced. This document does not: — provide a method to classify a cleanroom with respect to particle deposition rate or particle obscuration rate; — directly consider the deposition of microbe-carrying particles, although they can be treated as particles; — give any consideration to surface deposition by contact as, for example, when personnel touch a product and contamination is transferred.
