This International Standard provides parameters based on values for hand/arm and approach speeds and the methodology to determine the minimum distances from sensing or actuating devices of protective equipment to a danger zone.
These specific devices are:
a) trip devices as defined in EN 292-1:1991, 3.23.5 (specifically electro-sensitive protective equipment, pressure sensitive mats), including those used additionally to initiate operation;
b) two-hand control devices as defined in EN 292-1:1991, 3.23.4 and covered by ISO 13851.
NOTE For the purposes of this International Standard, hold-to-run controls, which are designed to be actuated with one hand, are not considered to be protective equipment.
This International Standard does not apply to protective equipment which is intended to be moved, without tools, nearer to the danger zone than the calculated distance, e.g. pendant two-hand control devices.
The minimum distances derived from this International Standard do not apply to protective equipment used to detect the presence of persons within an area already protected by a guard or electro-sensitive protective equipment.
