This International Standard defines dimensions and specifies performance and safety requirements for traction aid winches used in forestry for assisting supported machines while going uphill and downhill (pulling and braking). It is applicable to fixed and detachable winches and their components, connections and communications, which are used with mobile and self-propelled forestry machinery as defined in ISO 6814 such as harvesters, forwarders, skidders, planting machines, machines for forest ground preparation and machines for extracting residual waste. It is also applicable to remote traction aid winch systems which are installed on a position away from the supported machine. It is not applicable to winches which are not using a controlled rope force while going downhill and winches used for skidding, hoisting operations on cranes, draglines, high lead logging, rope logging systems or yarding. This standard is intended to be applied to traction aid systems used on machines, where without use of these systems the machine would remain stationary on slopes under its independent control (see Appendix D).

Forestry machines, as defined in ISO 6814 that are used as anchor or supported machines, are not in the scope of this standard. For guidance refer to EN ISO 11850.

This part of ISO 11680 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, pole-mounted powered pruners (hereafter named "machine"), including extendable and telescopic machines, having an integral combustion engine as their power source. These machines use a power transmission shaft to transmit power to a cutting attachment consisting of a saw chain and guide bar, a reciprocating saw blade or a single-piece circular saw blade with a 205 mm maximum outside diameter. 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.

This part of ISO 11680 deals with all significant hazards, hazardous situations or hazardous events with the exception of electric shock from contact with overhead electric lines (apart from warnings and advice for inclusion in the instructions), relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).

This part of ISO 11680 is applicable to portable, hand-held, pole-mounted powered pruners manufactured after its date of publication.

NOTE Brush cutters with a circular saw blade are not included in the scope of this standard. Brush cutter requirements are outlined in ISO 11806-1.

This part of ISO 11680 gives safety requirements and measures for their verification for the design and construction of portable, hand-held, pole-mounted powered pruners with a backpack power unit and using a power transmission shaft to transmit power to a cutting attachment consisting of a saw chain, a reciprocating saw blade or a single-piece circular saw blade (hereafter referred to as "machine"). 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.

This part of ISO 11680, together with the relevant sections of ISO 11680-1, deals with all significant hazards, hazardous situations or hazardous events with the exception of electric shock from contact with overhead electric lines (apart from warnings and advice for inclusion in the instructions) and whole-body vibration from the backpack power unit, relevant to these machines when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

NOTE 1 A standardized test procedure for measuring whole-body vibration from the backpack power unit is presently not available.

NOTE 2 See Annex A for a list of significant hazards.

This part of ISO 11680 is applicable to portable, hand-held, pole-mounted powered pruners with backpack power unit manufactured after its date of publication.

This document establishes a laboratory test method and performance requirements for thrown object guards (TOG) that provide operator protection against thrown objects. This applies to mobile and self-propelled machinery used in forestry and related operations including, but not limited to those defined in ISO 6814. The TOG is intended to provide reasonable protection for the operator on the host machine from powered rotating cutting or grinding elements and residual matter thrown by an attachment on the host machine.

This document does not address protection from chain-shot hazards. A separate standard ISO/DIS 21876 addresses chain-shot hazards.

This particular type of hazard is specifically defined by the mass, velocity and profile to include any cutting-edge geometry of the cutter or grinding element and is unique to each cutting or grinding attachment and its host machine.
