ISO 13373-2:2016 recommends procedures for processing and presenting vibration data and analyzing vibration signatures for the purpose of monitoring the vibration condition of rotating machinery, and performing diagnostics as appropriate. Different techniques are described for different applications. Signal enhancement techniques and analysis methods used for the investigation of particular machine dynamic phenomena are included. Many of these techniques can be applied to other machine types, including reciprocating machines. Example formats for the parameters that are commonly plotted for evaluation and diagnostic purposes are also given. ISO 13373-2:2016 is divided essentially into two basic approaches when analysing vibration signals: the time domain and the frequency domain. Some approaches to the refinement of diagnostic results, by changing the operational conditions, are also covered. ISO 13373-2:2016 includes only the most commonly used techniques for the vibration condition monitoring, analysis and diagnostics of machines. There are many other techniques used to determine the behaviour of machines that apply to more in‑depth vibration analysis and diagnostic investigations beyond the normal follow‑on to machinery condition monitoring. A detailed description of these techniques is beyond the scope of ISO 13373-2:2016, but some of these more advanced special purpose techniques are listed in Clause 5 for additional information. For specific machine types and sizes, the ISO 7919 and ISO 10816 series provide guidance for the application of broadband vibration magnitudes for condition monitoring, and other documents such as VDI 3839 provide additional information about machinery‑specific problems that can be detected when conducting vibration diagnostics.

Le présent document spécifie des procédures recommandées pour le traitement et la présentation des données vibratoires et l'analyse des signatures vibratoires aux fins de surveillance des vibrations des machines tournantes et la réalisation de diagnostics, le cas échéant. Il décrit différentes techniques en fonction des diverses applications. Il présente par ailleurs des techniques d'amélioration des signaux et des méthodes d'analyse destinées à l'étude des phénomènes dynamiques de machines spécifiques. Plusieurs de ces techniques peuvent être appliquées à d'autres types de machines y compris les machines alternatives. Il donne en outre des exemples de formats pour des paramètres communément représentés aux fins d'évaluation et de diagnostic. La présente partie 2 est essentiellement fondée sur deux principes de base pour l'analyse des signaux de vibration : le domaine temporel et le domaine fréquentiel. Certaines méthodes d'affinement des résultats du diagnostic par variation des conditions de fonctionnement sont également couvertes.
