Specifies the minimum safety distances from a barrier to the danger zone of a machine to prevent the danger zone being reached by the upper limbs of a person of age 3 years and above. The Standard is applicable only where safety can be assured by distance alone. The Standard will not provide sufficient protection against radiation or substances emitted from the machine.

This Standard establishes values for safety distances to prevent danger zones being reached by the upper limbs of persons of 3 years of age and above. The distances apply when adequate safety can be achieved by distances alone.These safety distances will not provide sufficient protection against certain hazards, for example radiation and emission of substances. For such hazards, additional or other measures need to be taken.The safety distances protect those persons who try to reach danger zones without additional aid and under the conditions specified for the different reaching situations.This Standard need not be applied to machinery which is covered by certain electrical standards in which specific testing procedures are laid down, for example using the test finger. For certain applications there are justifiable reasons to deviate from these safety distances. Standards dealing with these applications indicate how an adequate level of safety can be achieved.
