ISO 11806-2:2011提供了安全要求和措施，用于验证便携式手持电动刷刀和草坪修剪器的设计和构造，其中包括背包式内燃机动力源和机械动力传递电源和切割附件。规定了消除或减少使用这些机器的危险的方法以及制造商提供的关于安全工作实践的信息的类型。 ISO 11806-2:2011不适用于配备有多个部件的金属刀片的草坪边缘修剪器或刷子，例如。枢转链。 ISO 11806-2:2011与ISO 11806-1的相关条款一并处理，除了与背包式动力装置相关的全身振动外，还涉及所有重大危险，危险情况和危险事件。机器在按照意图使用并在制造商可合理预见的误用条件下使用

ISO 11806-2:2011 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, powered brush-cutters and grass-trimmers with a back-pack-mounted combustion engine power source and mechanical power transmission between the power source and the cutting attachment. Methods for the elimination or reduction of hazards arising from the use of these machines and the type of information on safe working practices to be provided by the manufacturer are specified. ISO 11806-2:2011 is not applicable to lawn-edge trimmers or to brush-cutters equipped with metallic blades consisting of more than one part, e.g. pivoting chain. ISO 11806-2:2011, taken together with the relevant clauses of ISO 11806-1, deals with all significant hazards, hazardous situations and hazardous events, with the exception of whole-body vibration from the back-pack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
