TS EN 12786

TS EN 12786 is a guidance document for drafting the vibration-related clauses of machinery safety standards. Its role is to help standard writers handle vibration in a consistent way when it is included in a safety standard, focusing on terminology, structure and wording rather than on setting a single machine-specific performance limit.

What vibration clauses are meant to address

In general technical terms, vibration is the oscillatory motion of a machine, a component, or the whole equipment during operation. In safety standards, it is often connected with operator exposure, user comfort, machine stability, controllability and, in some cases, measurement or evaluation approaches. A guidance document like this helps authors use vibration terms consistently and create clauses that can be compared across different machinery standards.

Its place in machinery safety standardization

This document belongs to the preparation of machinery safety standards and provides a common framework for vibration topics. Vibration may interact with other technical subjects such as noise, force, motion and exposure, so clear definitions matter. Such guidance supports more consistent drafting and reduces ambiguity when the same technical phenomenon appears in different sectoral standards.

This record refers to EN 12786:1999 and is listed as a withdrawn standard. It should therefore be understood as a methodological technical document for drafting safety-standard clauses, not as an independent conformity specification for a particular machine or product.
