TS EN ISO 3457

TS EN ISO 3457. OFFICIAL SCOPE IS UNAVAILABLE. This title points to the technical area dealing with guards used on earth-moving machinery and the basic definitions and requirements associated with them. In general technical terms, a guard is a physical barrier or device intended to separate people or vulnerable machine parts from hazards such as moving components, falling objects, flying debris, and pinch points.

What a guard does on heavy machinery

On earth-moving machines, guards may surround rotating, reciprocating, or otherwise hazardous parts. In common engineering practice, they can be fixed, movable, lockable, or access-controlled depending on the function they must serve. Their purpose is to balance safe access for operation and maintenance with protection against unintended contact with dangerous zones. This topic concerns not only the enclosure itself, but also the guard’s strength, placement, accessibility, and compatibility with machine operation.

Why terminology and requirements matter in this field

The phrase “definitions and requirements” indicates a standardization approach aimed at aligning terminology and setting a common framework for guard-related expectations. Such documents help manufacturers, designers, service teams, and the supply chain use the same terms with the same meaning. In the context of earth-moving machinery, guards are key safety-related elements on equipment such as excavators, loaders, dozers, graders, and similar machines with exposed moving systems. This record represents a withdrawn TS EN ISO standard, so it is useful for understanding the subject area, but it should not be treated as a current requirement document.
