• Tên tiếng Anh / Title in English: Safety of machinery - Pressure-sensitive protective devices - Part 3: General principles for design and testing of pressure-sensitive bumpers, plates, wires and similar devices (ISO 13856-3:2013)
• Phạm vi áp dụng / Scope of standard: This part of ISO 13856 establishes general principles and specifies requirements for the design and testing of 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, and the majority of which are produced for specific applications and are not available as “off-the-shelf” items. This part of ISO 13856 also gives specific requirements for the following pressure-sensitive protective devices: a) pressure-sensitive bumpers; b) pressure-sensitive plates; c) pressure-sensitive wires (trip wires). It deals with the design of a pressure-sensitive device with regard to safety and reliability rather than its suitability for particular applications. NOTE 1 For the relationship between safety and reliability, see ISO 13849-1:2006, 4.2. NOTE 2 The machinery manufacturer and/or user is responsible for installing appropriate types of protective device based on a risk assessment. It is not applicable to — specifying the dimensions of pressure-sensitive protective devices in relation to any particular application, or — stopping devices according to IEC 60204-1 used for the normal operation, including emergency stopping of machinery. NOTE 3 Specific requirements for particular applications are intended to be set forth in relevant type-C standards (see ISO 12100 and Introduction). Additional requirements can be necessary where pressure-sensitive protective devices are used in locations accessible to elderly or disabled people or children. NOTE 4 While requirements are given for the immunity of the device to electromagnetic disturbances, these are not intended to cover all aspects of electromagnetic compatibility (EMC).
