TS EN 12786
Safety of machinery- Guidance for the drafting of the vibration clauses of safety standards
This European Standard gives guidance for the writers of harmonized type-C machinery safety standards on how to deal with vibration where hand-transmitted vibration and/or whole-body vibration is identified as a significant hazard.
This European Standard also gives guidance on how to deal with the requirement for declaration of the vibration emission of portable hand-held and/or hand-guided machinery and for mobile machinery.
This European Standard supplements EN ISO 12100.

About This Item
TS EN 12786 is a guidance document for dealing with vibration in machinery safety standards. It supports the drafting of harmonized type-C machinery safety standards where hand-transmitted vibration and whole-body vibration are identified as significant hazards, and it also helps writers frame the requirements for declaring vibration emission for portable hand-held, hand-guided machinery and mobile machinery.
Why vibration clauses need dedicated treatment
In machinery, vibration is not just a comfort issue; it is a safety and usability parameter that can affect exposure, control, and task performance. Hand-transmitted vibration is conveyed through the hands and arms, while whole-body vibration reaches the operator through seating, standing platforms, or other contact surfaces. That distinction matters when a standard defines hazards, specifies how information should be presented, and determines what kind of emission declaration is relevant to a given machine category.
What this standard guides writers to address
- How vibration hazards are handled in harmonized type-C machinery safety standards.
- Situations where hand-transmitted and/or whole-body vibration is considered a significant hazard.
- How to frame requirements for vibration emission declaration for portable hand-held machinery, hand-guided machinery, and mobile machinery.
- Its role as a supplement to EN ISO 12100, providing drafting guidance rather than machine-specific design requirements.
In general technical terms, vibration-related requirements are closely linked to the source of the vibration, the operating mode, exposure duration, and the way results are expressed. Guidance standards like this help achieve consistent terminology and comparable declarations across different machine families, so the standard writer can structure vibration provisions in line with the wider safety strategy.
Accordingly, TS EN 12786 functions as a drafting guide for vibration clauses rather than as a measurement standard or a standalone product requirement document.
