Safety of machinery — Pressure-sensitive protective devices — Part 3: General principles for the design and testing of pressure-sensitive bumpers, plates, wires and similar devices

ISO 13856-3:2006 gives basic requirements for those pressure-sensitive protective devices, with or without an external reset facility, that are not specified in either ISO 13856-1 or ISO 13856-2, the majority of which are produced for specific applications and are not available as off-the-shelf items. It also gives specific requirements for pressure-sensitive bumpers, pressure-sensitive plates and pressure-sensitive wires (trip wires).
