Safety of machinery - Positioning of safeguards with respect to the approach speeds of parts of the human body

ISO 13855:2010 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 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. Safeguards considered in ISO 13855:2010 include: - electro-sensitive protective equipment, including light curtains and light grids (AOPDs), and laser scanners (AOPDDRs) and two-dimensional vision systems; - pressure-sensitive protective equipment, especially pressure-sensitive mats; - two-hand control devices; - interlocking guards without guard locking.

Le présent document définit les éléments à prendre en considération pour évaluer le temps d'obtention de l'arrêt et le temps d'accès à des éléments mobiles d'une machine en fonction des dispositifs de protection mis en oeuvre dans le cadre des dispositions réglementaires en vigueur en matière de prévention des accidents du travail. Il vient à l'appui des Directives "Machines 98/37/CE et 2006/42/CE.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
