Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method equivalent to the international standard ISO 11839:2010 "Forbidden barriers used in forestry machinery cab guards Test methods and performance requirements for glass and baffle materials for throwing serrations, also included in ISO 11839:2010/COR.1.2012 content.

The documents of our country that have a consistent correspondence with the international documents referenced in this standard are as follows.

2009, IDT)

This standard is proposed and managed by the National Forestry Machinery Standardization Technical Committee (SAC/TC61).

Introduction

An accidental installation of a forestry machine with a circular saw blade that can replace the serrations during the operation can cause the sawtooth to disengage from the saw blade.

The operator of the guard brings some damage, consisting of a structural component and a spacer material between the operator and the potentially hazardous area.

The device blocks the hazards from a variety of hazardous conditions to protect the safety of forestry machinery operators (eg ISO 8083) Fall protection structure or ISO 8084 anti-puncture protection structure).

According to this standard, the safety device composed of appropriate separator and glass material can be selected to protect the forestry machinery operators from aliasing.

The damage caused by the throwing of the circular saw blade. Although materials meeting the above criteria are not possible at all possible throwing sawtooth impact machines Provide protection in case of hazard, but the implementation of this standard can cause the sawtooth to detach from the circular saw blade under normal working conditions of the circular saw blade to cause the projectile Provide protection to the operator.

Used in forestry machinery cab guards Glass and separator materials that block throwing serrations Test methods and performance requirements Note. Certain tests specified in this standard may present a hazard.

1 Scope

This standard stipulates that in order to avoid the loss of the sawtooth from the saw blade when the forestry machine with a circular saw blade is used, the projectile will cause damage to the operator.

Test methods and performance requirements for the installed barrier protection capabilities. The hazard referred to in this standard refers specifically to the serrated rule of the test cutting device.

The danger of inch and throw speed.

This standard applies to forestry machinery as defined in ISO 6814 [including integral circular saw blades or insert circular saw blades controlled or driven by the main engine) Protective barrier material (eg, cut-off saw, fell saw, and saw).

This standard does not address the protection of saw chain slamming hazards (see ISO 11837).
