This standard 20/30363686 DC BS EN ISO 11839. Machinery for forestry. Glazing and panel materials used in operator enclosures for protection against thrown sawteeth. Test method and performance criteria is classified in these ICS categories:

• 65.060.80 Forestry equipment

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.
