NF EN ISO 11681-1

ISO 11681-1:2004 deals with the significant hazards and specifies safety requirements and their verification for design and construction of portable combustion-engine, hand-held chain-saws, designed only for use by one operator and intended for forest work. It describes methods for the elimination or reduction of hazards arising from their use. In addition it specifies the type of information on safe working practices to be provided by the manufacturer. It deals with all significant hazards. It does not cover the hazard from kickback for machines with an engine displacement over 80 cm3. The environmental aspects, except for noise, have not been considered in this standard. Chain-saws covered by ISO 11681-1:2004 are designed for use by persons having read and understood the safety requirements in the instruction handbook and using the appropriate personal protective equipment (PPE). The chain-saws covered are designed only to be operated with the right hand on the rear handle and the left hand on the front handle. ISO 11681-1:2004 is not applicable to chain-saws which are manufactured before the date of publication of this document.

ISO 11681-1:2011 gives safety requirements and measures for their verification for the design and construction of portable, combustion-engine, hand-held chain-saws, intended to be used for forest work by only one operator, by persons with the right hand on the rear handle and left hand on the front handle having read and understood the safety requirements provided in the instruction handbook and using the appropriate personal protective equipment (PPE). 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 11681-1:2011 deals with all significant hazards, hazardous situations and hazardous events, with the exception of kickback and balance for machines with an engine displacement of more than 80 cm3, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
