ISO 3691-3:2016规定了除ISO 3691-1规定的安全要求外，对于带有垂直非倾斜桅杆的工业卡车的安全要求及其验证方法: a） 具有提升操作员位置的卡车，以及ISO 5053-1中定义的订单分拣卡车，其中提升操作员位置和负载处理装置提升至地面以上1200 mm的高度； b） ISO 5053-1中定义的横向和前部堆垛卡车，设计为在卡车行驶时，装载装置升高至地面以上1200 mm以上，装载装置升高、降低或横向移位、装载或空载。 这些卡车设计为在光滑、水平的表面（如混凝土）上在室内行驶，在使用时可引导、无引导或两者兼有； 他们不打算拖或推。 ISO 3691-3:2016不适用于装卸两种货物的堆垛机卡车，一种装载在货叉上，另一种装载在支撑臂上，此类卡车受ISO 3691-1的保护。 它不适用于升降操作员位置小于等于1200 mm的卡车，或专门设计用于在叉车高度小于等于1200 mm的情况下行驶的卡车。 它不适用于提升操作员位置高达1200 mm（包括1200 mm）且可配备额外负载提升装置（最大提升高度为1800 mm）的低级订单分拣机。 ISO 3691-3:2016涉及附录A中所列的所有重大危险、危险情况或危险事件，这些危险、危险情况或事件与按照预期使用的适用机器有关，并且在制造商可以合理预见的误用条件下使用。 它没有规定在公路上使用卡车或在潜在爆炸性环境中作业时可能发生的危险的要求。 ISO/TS 3691-7和ISO/TS 3691-8中阐述了ISO 3691本部分要求之外的区域要求。

ISO 3691-3:2016 gives safety requirements and the means for their verification, additional to those of ISO 3691？1, for industrial trucks with a vertical, non-tilting mast: a) those trucks having an elevating operator position, and order？picking trucks, as defined in ISO 5053？1, where the elevating operator position and the load？handling device lifts to a height of more than 1 200 mm above ground level; b) lateral- and front-stacking trucks, as defined in ISO 5053？1, designed to travel with a load-handling device elevated more than 1 200 mm above ground level, with the load-handling device elevated, lowered or laterally displaced, laden or unladen, while the truck is travelling. These trucks are designed to travel indoors on a smooth, level surface (e.g. concrete) and can be guided, unguided, or both, when in use; they are not intended to tow or push. ISO 3691-3:2016 is not applicable to stacker trucks which handle two loads, one on the forks and the other on the support arms, this type of truck being covered by ISO 3691？1. It is not applicable to trucks with an elevating operator position up to and including 1 200 mm, or to trucks specifically designed to travel with an elevated load having a fork height up to and including 1 200 mm above ground level. It is not applicable to low-level order pickers with elevating operator's position up to and including 1 200 mm lift height which can be equipped with an additional load lifting device having a maximum lift height of 1 800 mm from ground level. ISO 3691-3:2016 deals with all significant hazards, hazardous situations, or hazardous events, as listed in Annex A, relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It does not establish requirements for hazards that can occur when using trucks on public roads or when operating in potentially explosive atmospheres. Regional requirements, additional to the requirements given in this part of ISO 3691, are addressed in ISO/TS 3691？7 and ISO/TS 3691？8.
