BS EN ISO 13855:2010 Safety of machinery. Positioning of safeguards with respect to the approach speeds of parts of the human body BS EN ISO 13855 is an International Standard which establishes the positioning of safeguards with respect to 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 from actuating devices of safeguards. The values for approach speeds (walking speed and upper limb movement) in BS EN are time tested and proven in practical experience. BS EN gives guidance for typical approaches. Other types of approach, for example running, jumping or falling, are not considered in BS EN . Safeguards considered in BS EN include: a) electro-sensitive protective equipment [see (all parts)], including: Light curtains and light grids (AOPDs) Laser scanners (AOPDDRs) and two-dimensional vision systems b) pressure-sensitive protective equipment (see , and ), especially pressure-sensitive mats c) two-hand control devices d) Interlocking guards without guard locking. BS EN 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). Protection against the risks from hazards arising from the ejection of solid or fluid materials, emissions, radiation and electricity are not covered by this International Standard.
