TS EN ISO 3457

TS EN ISO 3457 is a standard that establishes the principal terms used for earth-moving machinery and sets out the requirements and characteristics of guards and other means intended to protect personnel from mechanical, fluid, and thermal hazards. Its focus is on the risks that arise during intended use, routine maintenance, and normal operation as defined by the manufacturer.

What “guards” mean in this machinery context

In this technical field, a guard is not limited to a simple cover. The term covers barriers, enclosures, shields, and similar protective arrangements that separate people from moving parts, hot surfaces, pressurised fluids, or splash-related hazards. For earth-moving machinery, using a common vocabulary tied to ISO 6165 helps designers, service teams, and operators speak about the same protective concept with the same technical meaning.

Technical boundaries covered by the standard

• Principal terms for earth-moving machinery
• Characteristics and requirements for guards and related protective means
• Protection against mechanical, fluid, and thermal hazards
• Application in the machine’s intended use as specified by the manufacturer
• Connection to the earth-moving machinery family defined in ISO 6165

The document functions primarily as a technical reference for terminology and the classification of protective measures rather than as a complete machine design manual. It is useful when interpreting how guarding concepts fit into the broader safety design of construction and excavation equipment. This listing is the TS EN ISO 3457 edition, and the listed edition is withdrawn.
