Specifies functional requirements and the principles of design for the emergency stop of machinery without regard to the energy source used to control the functions. It does not apply to hand guided machines, hand held portable machines or to machines where the provision of an emergency stop would not reduce the level of risk to operator or other person.

This Standard specfies functional requirements and design principles for the emergency stop of machinery, independent of the type of energy used to control the function.The requirements of this Standard apply to all machinery except the following:Machines in which the provision of emergency stop would not lessen the risk.Hand-held portable machines.Hand-guided machines.This Standard does not deal with functions such as reversal or limitation of motion, deflection, shielding, braking, or disconnecting, which may be part of the emergency stop function.
