scope:

This Standard specifies functional requirements and designprinciples for the emergency stop function on machinery,independent of the type of energy used. It does not deal withfunctions such as reversal or limitation of motion, deflection ofemissions (e.g. radiation, fluids), shielding, braking ordisconnecting, which can be part of the emergency stop function.The requirements for this International Standard apply to allmachines, with exception to: ? machines where an emergency stopwould not reduce the risk; ? hand-held or hand-operated machines.NOTE The requirements for the realization of the emergency stopfunction based on electrical/electronic technology are described inIEC 60204-1.
