Scope

This document specifies the strength requirements for the protective covers of cutting attachments for portable forestry brushcutters and lawn mowers powered by internal combustion engines, and describes the corresponding test methods to evaluate their safety in actual use. This ensures the safety of operators, protecting them from flying debris and accidental contact with cutting attachments.
Another aspect of safety is the dimensions of the protective covers for cutting attachments: the requirements for these dimensions are outlined in ISO 7918.
