TS 11902-3 EN 1005-3/T1 (N. tadili: TS EN 1005-3)

TS 11902-3 EN 1005-3/T1 (N. tadili: TS EN 1005-3): TS 11902-3 EN 1005-3/T1 is the Turkish adoption record for a standard dealing with recommended force limits when people operate machinery. Its subject is the fit between human physical capability and the forces applied during machine-related tasks, which is a core ergonomic issue in the design and use of controls, adjustments, and other manual interactions.

Where the force limits apply

The scope extends across the machine life cycle, including construction, transport, commissioning, use, decommissioning, disposal, and dismantling. In practice, this means the subject is not limited to normal operation alone; it also relates to installation, adjustment, cleaning, fault finding, maintenance, setting, teaching, and process changeover activities where an operator or technician must exert force on the machine or its controls.

In general technical terms, recommended force limits are used to help reduce excessive muscular effort, awkward exertion, and fatigue-related risk. They are part of the broader ergonomics discipline, where the acceptable force depends on the task context, posture, repetition, grip, and working conditions rather than on one single universal value. This standard addresses that topic for machinery operation and related tasks.

What this edition represents

• Based on EN 1005-3 and listed here as TS 11902-3 EN 1005-3/T1.
• Withdrawn in this record, so it should be treated as an historical standard listing rather than an active edition.
• Useful for understanding the relationship between machinery safety, ergonomics, and human physical performance in force-demanding tasks.
