This International Standard specifies the safety requirements for controls and control systems for the following automated functions of industrial trucks: ¯# steering (excluding direct mechanical guidance); ¯# travel; ¯# lifting and lowering operations; ¯# load manipulations, e.g. rotation, reach, slewing, tilting, clamping; ¯# combination and/or sequence of the above movements. NOTE The control system is generally part of the truck but can include components external to the truck, e.g. the means of guidance for automated steering. This International Standard is intended for use in conjunction with one or more of the applicable parts of ISO 3691. This International Standard is not applicable to, and does not include, requirements for the following: ¯# safety equipment (e.g. devices for height limitation, speed limitation) used to override operator control; ¯# operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields); ¯# operation in environments subject to special rules (e.g. potentially explosive atmospheres); ¯# electromagnetic compatibility; ¯# transportation of passengers; ¯# handling of loads, the nature of which could lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials). Limitations in the scopes of the applicable parts of ISO 3691 also apply to this International Standard.
