Fans - Efficiency classification for fans - Part 4: Driven fans at maximum operating speed (ISO 12759-4:2019)

This document establishes a system for the classification of fan efficiency for all fan types driven by motors of nominal rating 0,125 kW and above. It applies to driven fans only, but not to the system (finished original equipment manufacturer's product, for example box fans and roof fans or ventilation system) in which they might be installed. This document describes a number of different procedures to classify the efficiency of a fan or to apply a minimum efficiency limit (MEL). Those procedures are described in:
—     ISO 12759-3;
—     this document (ISO 12759-4);
—     ISO 12759-5;
—     ISO 12759-6.
There is no method described to compare these classifications and MEL's.

Ventilatoren - Effizienzklassifizierung für Ventilatoren - Teil 4: Angetriebene Ventilatoren bei maximaler Betriebsdrehzahl (ISO 12759-4:2019)

Diese Internationale Norm legt ein System für die Klassifizierung des Ventilator-Wirkungsgrads bei allen Ventilatortypen fest, die von einem Motor mit einer Nennleistung von mindestens 0,125 kW angetrieben werden. Dies bezieht sich nur auf angetriebene Ventilatoren, aber nicht auf das System (Endprodukt des Originalgeräteherstellers, also z. B. Kastenventilatoren und Dachventilatoren oder Lüftungsanlagen), in das diese eingebaut sind. In diesem Dokument wird eine Reihe von verschiedenen Verfahren zur Klassifizierung des Ventilator-Wirkungsgrads bzw. zur Anwendung der Mindestwirkungsgradgrenze (en: minimum efficiency limit; MEL) beschrieben. Diese Verfahren werden in den folgenden Dokumenten beschrieben:
- ISO 12759 3;
- dieses Dokument (ISO 12759 4);
- ISO 12759 5;
- ISO 12759 6.
Es wird kein Verfahren zum Vergleich dieser Klassifizierungen und MELs beschrieben.

Ventilateurs - Classification du rendement des ventilateurs - Partie 4: Ventilateurs entraînés à vitesse maximale de fonctionnement (ISO 12759-4:2019)

Le présent document établit un système de classification du rendement de tous les types de ventilateurs entraînés par des moteurs dont la puissance nominale est de 125 kW et au-delà. Il est applicable aux ventilateurs (entraînés) uniquement. Il n'est pas applicable au système dans lequel les ventilateurs sont installés (produits finis du fabricant d'équipement d'origine, par exemple, les ventilateurs en caisson, les ventilateurs de toiture ou le système de ventilation). Le présent document décrit un nombre de procédures variées permettant de classifier le rendement d'un ventilateur ou d'appliquer une limite de rendement minimale (MEL). Ces procédures sont décrites dans:
—          ISO 12759‑3;
—          le présent document (ISO 12759‑4);
—          ISO 12759‑5;
—          ISO 12759‑6.
Il n'existe pas de méthode décrite permettant de comparer ces classifications et les MEL.

Ventilatorji - Klasifikacija učinkovitosti ventilatorjev - 4. del: Ventilatorji s pogonom pri največji obratovalni hitrosti (ISO 12759-4:2019)

Ta standard določa le besedišče vilic in priključkov za pretovarjanje. Dokument ne vsebuje varnostnih zahtev za vilice in priključke za pretovarjanje. V tem dokumentu izraz priključek opisuje napravo, nameščeno na industrijski tovornjak, ki omogoča alternativni način uporabe dvižnega sistema.
