ISO 13856-3:2013规定了一般原则，并规定了在有或没有外部复位设备的情况下，对ISO 13856-1或ISO 13856-2中没有规定的那些压敏保护装置的设计和测试要求，其中大部分是针对具体应用生产的，不可用作“现成”项目。 ISO 13856-3:2013还对以下压敏保护装置提供了具体要求:压敏保险杠;压敏板;压敏电线（跳闸线）。 它涉及压敏设备的设计，关于安全性和可靠性，而不是其针对特定应用的适用性。 不适用于任何具体应用的压敏保护装置的尺寸，或根据符合IEC 60204-1标准的装置，用于正常运行，包括机械的紧急停止。 尽管要求设备对电磁干扰的抗扰性，但这并不意味着涵盖电磁兼容性（EMC）的所有方面

ISO 13856-3:2013 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. ISO 13856-3:2013 also gives specific requirements for the following pressure-sensitive protective devices: pressure-sensitive bumpers; pressure-sensitive plates; 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. 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. 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).
