This part of ISO 14644 covers the classification of airborne molecular contamination (AMC) in cleanrooms and
associated controlled environments, in terms of airborne concentrations of specific chemical substances
(individual, group or category) and provides a protocol to include test methods, analysis and time weighted
factors within the specification for classification.
This part of ISO 14644 currently considers only concentrations of AMC between 100 and 10-12 g/m3 under
cleanroom operational conditions.
This part of ISO 14644 is not relevant for application in those industries, processes or production, where the
presence of airborne molecular substances is not considered a risk to the product or process.
It is not the intention of this part of ISO 14644 to describe the nature of airborne molecular contaminants.
This part of ISO 14644 does not give a classification of surface molecular contamination.
Dieser Teil der Internationalen Norm zu Reinräumen und zugehörigen Reinraumbereichen legt Anforderungen für die Klassifikation luftgetragener molekularer Kontamination fest. Es werden auch Protokolle für Prüfmethoden, Analysen und zeitgewichtete Faktoren für die Klassifikation beschrieben.
