BS EN ISO 11806:2008 Agricultural and forestry machinery. Portable hand-held combustion engine driven brush cutters and grass trimmers. Safety
BS EN ISO 11806 specifies safety requirements and their verification for design and construction of portable hand-held, combustion engine driven brush cutters and grass trimmers.
BS EN ISO 11806 describes methods for the elimination or reduction of risks arising from their use. In addition it specifies the type of information on safe working practices to be provided by the manufacturer. BS EN ISO 11806 contains a list of significant hazards it deals with and those it does not deal with.
BS EN ISO 11806 covers brush cutters as well as grass trimmers, because the design of both machines is basically identical. Frequently one and the same unit can be either a brush cutter or a grass trimmer, depending on what type of cutting attachment is used. As grass trimmers are often used in forestry, the relevant requirements have been included in this standard.
It does not give any technical requirement to reduce noise and vibration hazards. Indeed the different means available to reduce these risks are a matter for the technical information to which the manufacturer may resort, through specialised books or specific bodies.
BS EN ISO 11806 does not apply to backpack powered units, to lawn edge trimmers or to brush cutters equipped with metalic blades consisting of more than one part. Environmental aspects have not been considered. It applies primarily to machines which are manufactured after the date of issue of the standard.
