<p>ISO 13855:2010 establishes the positioning of safeguards with respect to the approach speeds of parts of the human body.</p> <p>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.</p> <p>The values for approach speeds (walking speed and upper limb movement) in ISO 13855:2010 are time tested and proven in practical experience. ISO 13855:2010 gives guidance for typical approaches. Other types of approach, for example running, jumping or falling, are not considered in ISO 13855:2010.</p> <p>Safeguards considered in ISO 13855:2010 include:</p> <p>- electro-sensitive protective equipment, including light curtains and light grids (AOPDs), and laser scanners (AOPDDRs) and two-dimensional vision systems;</p> <p>- pressure-sensitive protective equipment, especially pressure-sensitive mats;</p> <p>- two-hand control devices;</p> <p>- interlocking guards without guard locking.</p>
