适用范围：This International Standard specifies a test method and the corresponding strength requirements for cut-ting attachment guards of portable hand-held com-bustion 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 uninten-tional contacts with the cutting attachment. Another aspect of safety when designing a cutting attachment guard is its dimensions: required dimen-sions are given in ISO 7918. The present edition is ISO 7918:1985 and covers only circular saw-blade guards to brush-saws, but it is an-ticipated that the new edition will cover cutting attachment guard dimensions for portable brush-cutters, brush-saws and grass-trimmers. This International Standard does not apply to cutting attachment guards for lawn-trimmers, which are dealt with in ISO 10518[1].
