This standard specifies interlocking devices with protective devices that are not restricted by energy types (GB/T 15706.1--2007 gives the definitions of the following items: 3.26.1 "Interlocking device", 3.25.4 "Interlocking device" Lock guard'' and 3.25.5 "Interlock with guard lock") design and selection principles. This standard also puts forward special requirements for electrical interlocks (see Chapter 6). This standard applies to Components of guards that activate interlocks.
