Cleanrooms and associated controlled environments - Part 1: Classification of air cleanliness by particle concentration (ISO 14644-1:2015)
ISO 14644-1:2015 specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones; and separative devices as defined in ISO 14644‑7.
Only particle populations having cumulative distributions based on threshold (lower limit) particle sizes ranging from 0,1 µm to 5 µm are considered for classification purposes.
The use of light scattering (discrete) airborne particle counters (LSAPC) is the basis for determination of the concentration of airborne particles, equal to and greater than the specified sizes, at designated sampling locations.
ISO 14644-1:2015 does not provide for classification of particle populations that are outside the specified lower threshold particle-size range, 0,1 µm to 5 µm. Concentrations of ultrafine particles (particles smaller than 0,1 µm) will be addressed in a separate standard to specify air cleanliness by nano-scale particles. An M descriptor (see Annex C) may be used to quantify populations of macroparticles (particles larger than 5 µm).
ISO 14644-1:2015 cannot be used to characterize the physical, chemical, radiological, viable or other nature of airborne particles.
Reinräume und zugehörige Reinraumbereiche - Teil 1: Klassifizierung der Luftreinheit anhand der Partikelkonzentration (ISO 14644-1:2015)
Dieser Teil der ISO 14644 enthält die Klassifizierung der Luftreinheit in Reinräumen und zugehörigen Rein¬raumbereichen sowie von SD-Modulen (en: separative device, SD) nach ISO 14644 7 anhand der Konzentration luftgetragener Partikel.
Für Klassifizierungszwecke werden nur Partikelgruppen in Betracht gezogen, deren Summenhäufigkeits-verteilung auf dem Schwellenwert der Partikelgröße (untere (Nachweis-)Grenze) beruht, der von 0,1 µm bis 5 µm reicht.
Die Anwendung von Streulicht-Einzelpartikelzählern (LSAPC, en. light scattering (discrete) airborne particle counter) ist die Grundlage für die Bestimmung der Konzentration luftgetragener Partikel gleich und größer dem festgelegten Größenbereich an gekennzeichneten Probenahmeorten.
Dieser Teil der ISO 14644 trifft nicht auf die Klassifizierung von Partikelgruppen zu, die außerhalb des fest-gelegten unteren Schwellenwerts (Nachweisgrenze) der Partikelgröße im Bereich zwischen 0,1 µm und 5 µm liegen. Konzentrationen von ultrafeinen Partikeln (nanoskalige Partikel kleiner als 0,1 µm) werden in einem anderen Teil der Normenreihe behandelt, der die Luftreinheit anhand der Partikelkonzentration luftgetragener Nano¬partikel festlegt, während ein M-Deskriptor (siehe Anhang C) zur Quantifizierung von Makropartikelgruppen (Partikel größer als 5 µm) angewendet werden darf.
Dieser Teil der ISO 14644 eignet sich nicht zur Charakterisierung der physikalischen, chemischen, radiologischen sowie der lebensfähigen (aktiven) oder der anderen Arten von luftgetragenen Partikeln.
Salles propres et environnements maîtrisés apparentés - Partie 1: Classification de la propreté particulaire de l'air (ISO 14644-1:2015)
ISO 14644-1:2015 spécifie la classification de la propreté de l'air des salles propres, des zones propres et des dispositifs séparatifs tels que définis dans l'ISO 14644‑7 en termes de concentration des particules en suspension dans l'air.
Seules sont prises en compte les populations de particules présentant une distribution granulométrique cumulée dont le seuil inférieur se situe dans l'étendue de 0,1 µm à 5 µm.
La méthode de référence pour déterminer la concentration de particules dans l'air d'une taille supérieure ou égale aux tailles spécifiées aux points de prélèvement désignés est l'utilisation de compteurs utilisant les propriétés de diffusion de la lumière (light scattering airborne particle counters - LSAPC).
La présente partie de l'ISO 14644 ne donne pas de classification pour des populations de particules dont le seuil inférieur se situe en dehors de l'étendue granulométrique de référence de 0,1 µm à 5 µm. Les concentrations de particules ultrafines (plus petites que 0,1 µm) seront traitées dans une norme séparée laquelle spécifiera la propreté particulaire de l'air à l'échelle nanométrique. Un descripteur M (voir l'Annexe C) pouvant être utilisé pour quantifier les populations de macroparticules (particules plus grandes que 5 µm).
ISO 14644-1:2015 ne peut pas être utilisée pour caractériser la nature physique, chimique, radiologique ou viable des particules en suspension dans l'air.
Čiste sobe in podobna nadzorovana okolja - 1. del: Klasifikacija čistosti zraka na osnovi koncentracije delcev (ISO 14644-1:2015)
Ta del evropskega standarda določa klasifikacijo čistosti na osnovi koncentracije delcev v čistih sobah in prostorih z nadzorom čistega zraka v treh možnih stanjih glede na količino delcev, prisotnih v zraku.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
