Transmissions hydrauliques — Code d'essai pour la détermination du niveau de bruit aérien — Partie 3: Pompes — Méthode employant un étalage des microphones en parallélépipède

A new edition is under development: ISO/CD 4412-1.

Abstract / scope

This part closely follows the methods described in the two other parts, but allows the use of alternative pump mounting and drive configurations which are simpler and cheaper to implement in an anechoic chamber. May also be applied to test motors.
