[Current]Safety of machinery, Part 1903: Displays, controls, actuators and signals — Ergonomic requirements for the design of displays and control actuators — Control actuators
Adopts EN894-3:2000, which gives guidance on the selection, design and location of control actuators so that they are adapted to the requirements of the operators, are suitable for the task in question and take account of the circumstances of their use. It applies to manual control actuators used in equipment for occupational and private use.
