Cleanrooms and associated controlled environments - Part 8: Assessment of air cleanliness by chemical concentration (ACC) (ISO 14644-8:2022)
This document establishes typical assessment processes to determine grading levels of air chemical cleanliness (ACC) 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 for their determination. This document currently considers only concentrations of air chemical contaminants between 100 g/m3 and 10−12 g/m3 under cleanroom operational conditions.
This document is not relevant for application in those industries, processes or productions where the presence of airborne chemical substances is not considered a risk to the product or process.
It is not the intention of this document to describe the nature of air chemical contaminants.
This document does not give a classification of surface chemical contamination.
Reinräume und zugehörige Reinraumbereiche - Teil 8: Bewertung der chemischen Luftreinheit (ACC) (ISO 14644‑8:2022)
Dieses Dokument beschreibt die typischen Beurteilungsprozesse zur Bestimmung der Bewertungsstufen für die chemische Luftreinheit (ACC) in Reinräumen und zugehörigen Reinraumbereichen hinsichtlich der luftgetragenen Konzentrationen spezifischer chemischer Substanzen (einzeln, gruppenweise oder als Kategorien) und stellt ein Protokoll zur Verfügung, um Prüfverfahren, Analyse und Zeitgewichtungsfaktoren in die Bestimmung einzuschließen. Dieses Dokument betrachtet ausschließlich Konzentrationen von luftgetragenen chemischen Kontaminanten zwischen 100 g/m3 und 10−12 g/m3 unter Reinraumbetriebsbedingungen.
Dieses Dokument ist nicht anwendbar bei solchen Industriezweigen, Prozessen oder Produktionen, bei denen oder bei der das Vorhandensein von luftgetragenen chemischen Substanzen nicht als Risiko für das Produkt oder den Prozess betrachtet wird.
Es ist nicht Ziel dieses Dokuments, die Beschaffenheit luftgetragener chemischer Kontaminanten zu beschreiben.
Dieses Dokument gibt keine Klassifizierung für chemische Oberflächenkontamination vor.
Salles propres et environnements maîtrisés apparentés - Partie 8: Évaluation de la propreté chimique de l'air (ISO 14644-8:2022)
Le présent document établit les processus types d’évaluation permettant de déterminer les niveaux de gradation de la propreté chimique de l’air (ACC) dans les salles propres et les environnements maîtrisés apparentés, en termes de concentrations aéroportées de substances chimiques spécifiques (individuelle, groupe ou catégorie), et fournit un protocole permettant d’intégrer les méthodes d’essai, l’analyse et les facteurs de pondération pour leur détermination. Le présent document ne prend actuellement en compte que les concentrations de contaminants chimiques dans l’air comprises entre 100 g/m3 et 10−12 g/m3 dans des conditions d’exploitation de salles propres.
Le présent document ne s’applique pas aux secteurs industriels, aux procédés ou aux types de production où la présence de substances chimiques en suspension dans l’air n’est pas considérée comme un risque pour le produit ou le procédé.
Le présent document ne vise pas à décrire la nature des contaminants chimiques dans l’air.
Le présent document ne fournit pas de classification de la contamination chimique des surfaces.
Čiste sobe in podobna nadzorovana okolja - 8. del: Ocenjevanje čistosti zraka na osnovi koncentracije onesnaževal v zraku (ACC) (ISO 14644-8:2022)
Ta dokument določa tipične postopke ocenjevanja za določanje stopenj kemijske čistosti zraka (ACC) v čistih sobah in podobnih nadzorovanih okoljih v smislu koncentracij različnih kemijskih snovi v zraku (posameznih, skupin ali vrst) ter določa protokol
za vključitev preskusnih metod, analiz in časovno prilagojenih faktorjev v postopek njihovega določanja. Ta dokument trenutno obravnava samo kemijske onesnaževalce zraka v koncentraciji med 100 g/m3 in 10–12 g/m3
v obratovalnih pogojih čiste sobe.
Ta dokument se ne uporablja za industrije, procese in proizvodnje, kjer se prisotnost kemijskih snovi v zraku ne šteje za nevarno proizvodu ali procesu.
Ta dokument ni namenjen opisovanju lastnosti kemijskih onesnaževalcev zraka.
Ta dokument ne vsebuje klasifikacije kemijske onesnaženosti površja.
