Air intake filter systems for rotary machinery - Test methods - Part 2: Filter element endurance test in fog and mist environments (ISO 29461-2:2022)
This document specifies general test requirements, the test rig and equipment, the test materials and the test procedure and report for determining water endurance performance of air filter elements used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines.
The test evaluates water endurance performance of air filter elements under laboratory conditions. The performance results obtained in accordance with this document cannot be quantitatively applied (by themselves) to predict performance in service with regard to water endurance and lifetime.
Ansaugfiltersysteme von Rotationsmaschinen - Prüfverfahren - Teil 2: Dauertest für Filterelemente in Nebel- und Nebelumgebungen (ISO 29461-2:2022)
Dieses Dokument legt die allgemeinen Prüfanforderungen, den Prüfstand und die Prüfausrüstung, die Prüfmaterialien, das Prüfverfahren und den Prüfbericht für die Bestimmung des Wasserbeständigkeitsverhaltens von Luftfilterelementen fest, die in Lufteinlassfiltersystemen für Rotationsmaschinen wie stationäre Gasturbinen, Kompressoren und andere stationäre Verbrennungsmotoren verwendet werden.
Die Prüfung bewertet das Wasserbeständigkeitsverhalten von Luftfilterelementen unter Laborbedingungen. Die nach diesem Dokument für die Leistung ermittelten Ergebnisse können nicht unmittelbar zur quantitativen Vorhersage der Leistung bezogen auf Wasserbeständigkeit und Lebensdauer für den jeweiligen Anwendungsfall des Filters verwendet werden.
Systèmes de filtration d'air d'admission pour machines tournantes - Méthodes d'essai - Partie 2: Essai d'endurance d'élément filtrant en brouillard et environnement brumeux (ISO 29461-2:2022)
Le présent document spécifie les exigences générales d'essai, le banc et les équipements d'essai, les produits pour l'essai, le mode opératoire d'essai et le rapport pour la détermination des performances de résistance à l'eau des éléments filtrants utilisés dans les systèmes de filtration d'air d'admission des machines tournantes comme les turbines à gaz stationnaires, les compresseurs et autres moteurs stationnaires à combustion interne.
L'essai évalue la performance de résistance à l'eau des éléments filtrants dans des conditions de laboratoire. Les données de performances obtenues conformément au présent document ne peuvent pas être utilisées quantitativement (par elles-mêmes) pour prédire les performances en service en termes de résistance à l'eau et de durée de vie.
Zračni filtrski sistemi rotacijskih strojev - Preskusne metode - 2. del: Preskus vzdržljivosti filtrskih elementov v okolju z meglo in sparino (ISO 29461-2:2022)
Ta standard določa splošne zahteve, preskuševalno opremo, kvalifikacijo, preskusne materiale, preskusni postopek in poročilo za ugotavljanje vzdržljivosti delovanja elementov v zračnih filtrskih sistemih rotacijskih strojev, kot so nepremične plinske turbine, kompresorji in drugi nepremični motorji z notranjim izgorevanjem.
