DIN EN ISO 13857:2006-07

This International Standard establishes values for safety distances in both industrial and public environments to prevent machinery hazard zones being reached. The safety distances are appropriate for protective structures. It also gives information about distances to impede free access by the lower limbs. It is applicable for people of 1,4 m body height and above (this includes at least the 5th percentile of persons of 14 years and older). In addition, for upper limbs only, it provides information for children older than 3 years where reaching through openings needs to be addressed. The clauses of the International Standard covering lower limbs apply when access by the upper limbs is not foreseeable according to the risk assessment. The safety distances are intended to protect those persons trying to reach hazard zones under the conditions specified. This International Standard does not provide safety distance information for Electro-Sensitive Protective Equipment (ESPE). This International Standard need not be applied to machinery which is covered by certain standards in which specific testing procedures for safety distances are laid down, for example using the test finger in electrical applications.
