EVS-EN ISO 13855:2025

EN ISO 13855 specifies requirements for the positioning and dimensioning of safeguards. It considers the approach of the human body or its parts toward hazards within the intended span of control as follows:

— the position and dimension of the detection zones of ESPE and pressure-sensitive mats and pressure-sensitive floors,
— the position of two-hand control devices and single control devices,
— the position of interlocking guards.

EN ISO 13855 also specifies requirements for the positioning of safety-related manual control devices (SRMCD) concerning the approach of the human body or its parts from within the safeguard space relative to:

— the position and dimension of the detection zones of ESPE and pressure-sensitive mats and pressure-sensitive floors, and
— the position and dimension of interlocking guards.

When evaluating the human body's or its parts' ability to access SRMCD from within the intended
safeguarded space, the requirements of this document are also applicable to determine the dimensions of safeguards. Approaches such as running, jumping or falling, are not considered in this standard.

EN ISO 13855 applies to safeguards used on machinery for the protection of persons 14 years and older. Safeguards considered in this document include:

a) electro-sensitive protective equipment (ESPE) such as:

— active optoelectronic protective devices (AOPDs);
— AOPDs responsive to diffuse reflection that have one or more detection zone(s) specified in two
dimensions (AOPDDRs-2D);
— AOPDs responsive to diffuse reflection that have one or more detection zone(s) specified in three dimensions (AOPDDRs-3D);
— vision-based protective devices using reference pattern techniques (VBPDPP);
— vision-based protective devices using stereo vision techniques (VBPDST);

b) pressure-sensitive mats and pressure-sensitive floors;

c) two-hand control devices;

d) single control devices;

e) interlocking guards.

The separation distances derived from this document do not apply to safeguards used solely for presence sensing function.
