Test methods for assessing the performance of gas-phase air cleaning media and devices for general ventilation - Part 3: Classification system for GPACDs applied to treatment of outdoor air (ISO 10121-3:2022)

This document establishes a classification system for GPACDs supplying single pass outdoor air to general ventilation systems using outdoor air polluted by local urban sources and/or long-distance pollution. The classification system is intended to aid in assessing molecular contamination in addition to the particulate contamination dealt with by ISO 16890-1.
This document specifies four reference pollutants, i.e. ozone, sulphur dioxide, nitrogen dioxide and toluene, used for the classification due to their relevance to the intended application. This document further specifies three duty levels that are assigned for each pollutant reflecting the typical performance range of devices intended for the application. Since selection of reference pollutants and duty levels are specific and unique to the intended application, all other applications are excluded. In particular, this document does not apply to GPACDs in recirculation applications and/or dealing with pollution from indoor sources as well as pharmaceutical, microelectronic, nuclear, homeland security and military applications.

Methode zur Leistungsermittlung von Medien und Vorrichtungen zur Reinigung der Gasphase für die allgemeine Lüftung - Teil 3: Klassifizierungssystem für GPACDs für die Behandlung von Außenluft (ISO 10121-3:2022)

Dieses Dokument legt ein Klassifizierungssystem für GPACDs fest, die nach einmaliger Durchströmung allgemeine Belüftungssysteme mit Außenluft versorgen und Außenluft verwenden, die durch lokale urbane Quellen und/oder weiträumige Verunreinigungen verschmutzt ist. Zweck des Klassifizierungssystems ist es, die Beurteilung der molekularen Kontamination zusätzlich zu der in ISO 16890 1 behandelten Partikelkontamination zu unterstützen.
In diesem Dokument werden vier Referenzschadstoffe genannt: Ozon, Schwefeldioxid, Stickstoffdioxid und Toluol, die aufgrund ihrer Relevanz für die bestimmungsgemäße Verwendung für die Klassifizierung verwendet werden. In diesem Dokument werden außerdem jedem Schmutzstoff drei Beanspruchungsgrade zugewiesen, die den üblichen Leistungsbereich der für die Anwendung vorgesehenen Vorrichtungen wiedergeben. Da die Auswahl der Referenzschmutzstoffe und der Beanspruchungsgrade spezifisch ist und nur für den bestimmungsgemäßen Gebrauch gilt, sind alle anderen Anwendungen ausgeschlossen. Insbesondere gilt dieses Dokument nicht für GPACD in Rezirkulationsanwendungen und/oder die Verschmutzung aus Innenraumschmutzstoffen sowie pharmazeutische, mikroelektronische, nukleare, Heimatschutz- und militärische Anwendungen.

Méthodes d’essai pour l’évaluation de la performance des médias et des dispositifs de filtration moléculaire pour la ventilation générale - Partie 3: Système de classification pour les GPACD appliqués au traitement de l’air extérieur (ISO 10121-3:2022)

Le présent document établit un système de classification pour les GPACD fournissant de l’air extérieur en passage unique à des systèmes de ventilation générale utilisant de l’air extérieur pollué par des sources urbaines locales et/ou une pollution à longue distance. Le système de classification est destiné à aider pour l’évaluation de la contamination moléculaire en plus de la contamination particulaire traitée par l’ISO 16890-1.
Le présent document spécifie quatre polluants de référence, c’est-à-dire l’ozone, le dioxyde de soufre, le dioxyde d’azote et le toluène, utilisés pour la classification du fait de leur pertinence pour l’application prévue. Le présent document spécifie trois niveaux de service qui sont assignés pour chaque polluant reflétant la plage de performance typique des dispositifs prévus pour l’application. Puisque le choix des polluants de référence et des niveaux de service est spécifique et unique pour l’application prévue, toutes autres applications sont exclues. En particulier, le présent document ne s’applique pas aux GPACD dans les applications de recirculation et/ou le traitement de la pollution provenant de sources intérieures ainsi que les applications pharmaceutiques, microélectroniques, nucléaires, de sécurité intérieure et militaires.

Preskusna metoda za ocenjevanje zmogljivosti sredstev in naprav za čiščenje plinske faze za splošno prezračevanje - 3. del: Sistem klasifikacije za GPACD, ki se uporablja za obdelavo zraka na prostem (ISO 10121-3:2022)

Ta del standarda ISO 10121 vzpostavlja sistem klasifikacije za naprave za čiščenje plinske faze (GPACD), ki dovajajo dodaten zrak v splošne prezračevalne sisteme, ki uporabljajo zunanji zrak, onesnažen z emisijami iz lokalnih mestnih virov in/ali oddaljenih virov onesnaženja. Sistem klasifikacije je predviden kot pomoč pri ocenjevanju molekularnega onesnaženja poleg onesnaženja s trdnimi delci, ki je obravnavano v standardu ISO 16890-1.
