Fans — Determination of airflow propelled through an open personnel door by a positive pressure ventilator

This document establishes a uniform method of laboratory testing for the determination of airflow propelled through an open personnel door by a positive pressure ventilator. NOTE The test described by this document is not entirely in accordance with ISO 5801, though it references several subclauses of ISO 5801 (such as the measurement of pressure and airflow). This document does not specify a testing procedure for the design, production or field test of any PPV, nor is it the purpose for this document to serve as a manual for the construction, validation or calibration of the test facility. This document does not apply to any item of equipment designed or intended for applications other than positive pressure ventilation.

Ventilateurs — Détermination du débit d'air propulsé par un ventilateur à pression positive à travers une porte ouverte

Le présent document établit une méthode uniforme d'essai en laboratoire pour la détermination du débit d'air propulsé par un ventilateur à pression positive à travers une porte ouverte. NOTE L'essai décrit dans le présent document n'est pas entièrement conforme à l'ISO 5801, bien qu’il fasse référence à plusieurs paragraphes de l'ISO 5801 (telles que le mesurage de la pression et du débit d'air). Le présent document ne spécifie pas une procédure d'essai pour la conception, la production ou l'essai sur le terrain d'un PPV, ni ne sert de manuel pour la construction, la validation ou l'étalonnage de l'installation d'essai. Le présent document ne s’applique pas à tout équipement conçu ou destiné à des applications autres que la ventilation à pression positive.
