ISO 18436-4 is an international standard that specifies the requirements for training, assessment, and certification of personnel who perform vibration analysis as part of machinery condition monitoring and diagnostics.
It forms part of the broader ISO 18436 series, which covers various techniques used to assess the condition of industrial equipment.
ISO 18436-4:2014 (the current version) outlines the competency levels and qualification criteria for professionals involved in vibration analysis.
It ensures that individuals conducting these tasks are properly trained and certified according to globally recognised standards.
The standard defines four categories (levels) of qualification:
| Level | Description |
|---|---|
| Category I | Basic understanding of vibration measurement and data collection under supervision. |
| Category II | Intermediate knowledge, capable of analysing and interpreting vibration data. |
| Category III | Advanced understanding; able to diagnose faults and manage condition monitoring programmes. |
| Category IV | Expert level; responsible for developing and approving condition monitoring strategies. |
This standard provides consistency and credibility in vibration analysis practices across industries.
It helps organisations:
