Full title and description

Condition monitoring and diagnostics of machines — Vibration condition monitoring — Part 2: Processing, analysis and presentation of vibration data. This International Standard gives recommended procedures for processing and presenting vibration data and for analysing vibration signatures to support condition monitoring and diagnostics of rotating (and, where applicable, other) machines.

Abstract

ISO 13373-2:2016 covers signal conditioning, time-domain and frequency-domain processing, signal‑enhancement techniques and common analysis methods for vibration-based condition monitoring. It describes example parameter formats and plotting conventions used for evaluation and diagnostic purposes, and lists additional, more advanced techniques (informative) for deeper diagnostic investigations. The standard focuses on the most widely used techniques applicable to routine condition monitoring and follow‑on diagnostics.

Scope

Provides recommended procedures for processing and presenting vibration measurement data and for analysing vibration signatures to monitor the condition of rotating machinery and to perform diagnostics as appropriate. The document describes both time‑domain and frequency‑domain approaches, signal‑enhancement and analysis methods for investigating machine dynamic phenomena, and example parameter formats for evaluation and diagnostic plotting. It does not attempt to describe every specialised or advanced diagnostic method in detail but references additional techniques and related standards for machine‑specific guidance.

Key topics and requirements

• Signal conditioning and measurement considerations for vibration transducers and interfaces.
• Time‑domain analysis approaches (waveform inspection, statistical/time metrics).
• Frequency‑domain analysis (FFT, spectral formats, harmonic and sideband analysis).
• Signal‑enhancement techniques (filtering, windowing, envelope analysis) for bearing and gear diagnostics.
• Practical guidance on plotting conventions and parameter formats for trending and diagnostic review.
• Use of operational‑condition variations to refine diagnostic conclusions.
• Reference and linkage to machine‑specific standards (e.g. ISO 7919, ISO 10816) for broadband magnitude interpretation.

Typical use and users

Used by condition monitoring practitioners, vibration analysts, reliability and maintenance engineers, diagnostics laboratories and equipment manufacturers. Typical applications include routine vibration monitoring programmes, diagnostic follow‑up investigations, development of trending plots and alarms, and as a reference for configuring data acquisition and processing in predictive‑maintenance systems.
