2.4 Minimum installation distance
Warning! The information given in this chapter shall be considered as an overview. For correct positioning, please
refer to the latest version of the complete standard EN ISO 13855 "Safety of machinery – Positioning of safeguards
with respect to the approach speeds of parts of the human body".
The safety device must be positioned at a distance that prevents a person or part of a person to reach the hazard
zone before the hazardous motion of the machine has been stopped by the AOPD.
According to EN ISO 13855:2010, the minimum distance to the hazard zone is calculated using:
S = (K × T) + C
S
Minimum distance (mm) between safeguard and hazard zone
K
Approach speed of body parts towards the hazard zone (mm/s). See below for values.
T
Overall system stopping performance (s) with T = T1 + T2, where:
T1 = response time of the AOPD (s).
T2 = stopping time of the machine, including the response time of the safety control system (s).
C
Intrusion distance (mm). C depends on the resolution d and the position of the detection zone. See below.
Vertically assembled AOPD
The minimum distance S for a vertically assembled AOPD is determined in three steps:
a) Calculation of the minimum distance for reaching through the detection zone, S
b) Calculation of the minimum distance for reaching over the detection zone, S
c) Comparison of S
RT
NB: If access to the hazard zone by reaching over the AOPD can be excluded, e.g. by the provision of guards or other
protective measures, step b) and c) are not necessary.
