scope:

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. 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 to be applied to machinery which is covered by certain electrical standards in which specific testing procedures are laid down, e.g. using the test finger. For certain applications there are justifiable reasons to deviate from these safety distances. Standards dealing with these applications shall indicate how an adequate level of safety can be achieved.
