Over deze norm
Specifies a test method and the corresponding strength requirements of portable hand-held combustion engine brush-cutters, for use primarily in forestry, and grass-trimmers, to test their safety in practical use. This ensures safety for the operator being protected from thrown objects and unintentional contacts with the cutting attachment. Required dimensions are given in ISO 7918. Does not apply to cutting attachment guards for lawn-trimmers, which are dealt with in ISO 10518.
