prEN ISO 13855
Main + amendment
ISO 13855 establishes the positioning of safeguards for the approach speeds of parts of the human body. It specifies parameters based on values for approach speeds of parts of the human body and provides a methodology to determine the minimum distances to a hazard zone from the detection zone or actuating devices of safeguards.

The values for approach speeds (walking speed and upper limb movement) in ISO 13855 are time-tested and proven in practical experience. ISO 13855 gives guidance for typical approaches. Other types of approaches, for example running, jumping or falling, are not considered in ISO 13855.

Safeguards considered in ISO 13855:

a) electro-sensitive protective equipment, including:

⎯ light curtains and light grids (AOPDs),

⎯ laser scanners (AOPDDRs) and two-dimensional vision systems,

b) pressure-sensitive protective equipment, especially pressure-sensitive mats,

c) two-hand control devices,

d) interlocking guards without guard locking.

ISO 13855 specifies minimum distances from the detection zone, plane, line, point or interlocking guard access point to the hazard zone for hazards caused by the machine (e.g. crushing, shearing, drawing-in). ISO 13855 does not apply to safeguards (e.g. pendant two-hand control devices) that can be moved, without using tools, nearer to the hazard zone than the calculated minimum distance. The text of ISO 13855:2010 has been approved in Europe as EN ISO 13855:2010 without any changes.
