In situ test methods for high efficiency filter systems in industrial facilities (ISO 16170:2016, Corrected version 2017-04)
ISO 16170:2016 specifies in situ test methods for high efficiency particulate air filters used to limit releases towards the environment (e.g. from nuclear facilities or facilities with aerosol toxic or biological releases). This applies where installations of these filters are used to clean effluent air before discharge to the environment from industrial (including nuclear) installations where toxic/radioactive/biological materials are handled or processed.
It excludes the application already covered by ISO 14644‑3.
The scope of ISO 16170:2016 includes detail of two methods, either of which applies to the periodic testing of high efficiency filters which are used in demanding applications aiming at protecting the environment, such as the nuclear industry.
In the case of nuclear applications, ISO 16170:2016 is applicable to installations covered by ISO 17873 (applications other than nuclear reactors) and ISO 26802 (nuclear reactors).
The two reference methods specified in ISO 16170:2016 are not equivalent, but related to, the requirements to be addressed by the test results. The choice of which of the two methods is adopted in any specific case depends on whether the outcome requires an integrity test or a statutory efficiency accountancy test.
For industries handling or processing radioactive or toxic materials giving rise to a risk of possible release, the main goal of the tests is to confirm that the filter installation is fit for purpose. In the case of integrity tests (Annex B), this is to confirm that no significant leakage of toxic aerosols through the filter installation is possible.
In the case of efficiency accountancy tests (Annex C), the test is designed to make an accurate measurement of decontamination factor with respect to the MPPS size range of particles.
The reference method described in Annex B (integrity test) requires a test aerosol of dispersed oil particles mainly submicrometre in size range, which is stable during the test procedure and compatible with other installation components. Particle concentrations are measured in real time by light scattering instrumentation (optical detectors).
The reference method described in Annex C (efficiency accountancy test) requires a test aerosol of particles having a narrow size range centred on MPPS size range for HEPA filter media. Their concentration both upstream and downstream the filters is measured by fluorimetric analysis of aqueous solution obtained by washing the membrane sampling filters.
It should be noted that the requirements for an efficiency accountancy test also cover the requirements of an integrity test, which is considered to be a minimum requirement.
Test methods developed in ISO 16170:2016 do not cover the other in situ performance requirements, such as mechanical resistance, bursting resistance or humidity resistance. Specific systems operating at high temperature or with specific gaseous effluents might require specific test methods.
The engineering design of HEPA and ULPA filter installations does not fall within the scope of ISO 16170:2016.
NOTE In the field of filters for general ventilation applications, ISO 29462 is a detailed and comprehensive description of a method which uses scanning and particle counting methods to evaluate the performance of a filter in terms of particle grade efficiency, as well as pressure drop. Such a method and procedure would not be applicable in those nuclear installations where quantification of the decontamin
Verfahren zur Prüfung von Luftfiltersystemen mit sehr hohen Wirkungsgraden im eingebauten Zustand (ISO 16170:2016, korrigierte Fassung 2017-04)
Diese Norm ist für Nutzer von HEPA- und ULPA-Filtern anwendbar, die die Leistung dieser in ihren Anwendungen eingebauten Filter vor Ort steuern wollen, insbesondere in einigen technischen Bereichen, in denen die Aerosolfilter verwendet werden, um die Freisetzung in die Umwelt einzuschränken (z. B. nukleare Anlagen oder Anlagen, aus denen toxische Aerosole oder biologische Stoffe freigesetzt werden). Von dieser Norm ist die Anwendung ausgenommen, die bereits in ISO 14644 3 (Reinräume und zugehörige Reinraumbereiche — Teil 3: Prüfverfahren) behandelt wird.
Der Anwendungsbereich dieser Norm umfasst Einzelheiten des Verfahrens bzw. der Verfahren, die für die regelmäßige Prüfung von HEPA- und ULPA-Filtern angewendet werden müssen, welche in anspruchsvollen Anwendungen mit dem Ziel, die Umwelt zu schützen, verwendet werden, wie z. B. in der Atomwirtschaft. Das schließt Beispiele für die anwendbare und nicht anwendbare Verwendung von Filtern ein sowie die Festlegung des Prüfintervalls, des Aerosoltyps, der Aerosolmischung und der Messverfahren.
Méthodes d'essai in situ pour les systèmes filtrants à très haute efficacité dans les installations industrielles (ISO 16170:2016, Version corrigée 2017-04)
L'ISO 16170 :2016 spécifie les méthodes d'essai in situ des filtres à très haute efficacité des particules contenues dans l'air utilisés afin de limiter les rejets dans l'environnement (par exemple, installations nucléaires ou installations rejetant des aérosols toxiques ou biologiques). Ceci s'applique lorsque des installations comprenant ces filtres sont utilisées, dans des installations industrielles (y compris nucléaires) dans lesquelles des matériaux toxiques/radioactifs/biologiques sont manipulés ou préparés, afin de nettoyer les effluents gazeux avant de les rejeter dans l'environnement.
Elle exclut l'application déjà traitée dans l'ISO 14644‑3.
Le domaine d'application de l'ISO 16170 :2016 inclut le détail de deux méthodes, qui s'appliquent toutes deux aux essais périodiques des filtres à très haute efficacité utilisés dans des applications exigeantes dans le but de protéger l'environnement, telles que l'industrie nucléaire.
Dans le cas des applications nucléaires, l'ISO 16170 :2016 est applicable aux installations couvertes par l'ISO 17873 (applications autres que les réacteurs nucléaires) et ISO 26802 (réacteurs nucléaires).
Les deux méthodes de référence spécifiées dans l'ISO 16170 :2016 ne sont pas équivalentes mais liées par les exigences présentées dans les résultats d'essai. Le choix d'utiliser l'une ou l'autre des deux méthodes dans chaque cas spécifique dépend si les résultats requièrent un essai d'intégrité ou un essai de quantification de l'efficacité à visée réglementaire.
Pour les industries manipulant ou préparant des matériaux radioactifs ou toxiques ayant pour conséquence un risque plus élevé de rejet possible, l'objectif principal des essais est de confirmer que l'installation de filtre est apte à l'emploi. Dans le cas d'essais d'intégrité (Annexe B), l'objectif est de confirmer qu'aucune fuite significative d'aérosols toxiques par l'installation de filtre n'est possible.
Dans le cas d'un essai d'efficacité réglementaire (Annexe C), l'essai est conçu pour faire une mesure précise du facteur de décontamination en fonction de la plage granulométrique MPPS.
La méthode de référence décrite à l'Annexe B (essai d'intégrité) requiert un aérosol d'essai de particules d'huile dispersées principalement dans la plage de dimensions submicronique, stable pendant le mode opératoire d'essai et compatible avec les autres composants de l'installation. Les concentrations de particule sont mesurées en temps réel par un détecteur à diffusion de lumière (détecteurs optiques).
La méthode de référence décrite à l'Annexe C (essai d'efficacité réglementaire) requiert un aérosol d'essai de particules ayant une plage de dimensions étroite centrée sur la plage granulométrique MPPS pour les média filtrants HEPA. Leurs concentrations en amont et en aval des filtres est mesurées par analyse fluométrique des solutions aqueuses obtenues en lavant la membrane des échantillons de filtres.
Il convient de noter que les exigences pour un essai d'efficacité réglementaire couvrent également les exigences d'un essai d'intégrité, qui est considéré comme une exigence minimum.
Les méthodes d'essai développées dans l'ISO 16170 :2016 ne couvrent pas les autres exigences de performance in situ telles que la résistance mécanique, résistance à l'éclatement ou résistance à l'humidité. Des systèmes spécifiques opérant à haute température ou produisant des effluents gazeux spécifiques peuvent être couverts par des méthodes d'essai spécifiques.

Ta standard se uporablja za nadzor onesnaženosti v industrijskih aplikacijah, kar med drugim vključuje jedrsko, farmacevtsko in mikroelektronsko industrijo, kjer je učinkovitost sistemov obvezen parameter.
