标准范围

本文件规定了投掷物防护装置（TOG）的实验室试验方法和性能要求，TOG可为操作员提供投掷物防护。这适用于林业和相关作业中使用的移动式和自行式机械，包括但不限于ISO 6814中定义的机械。TOG旨在为主机上的操作员提供合理的保护，使其免受动力旋转切割或研磨元件以及主机上附件抛出的残余物的影响。由于本文件中的测试取决于质量、速度和切割或磨削元件轮廓，因此符合本文件要求的TOG特定于每个切割或磨削附件和主机型号。本文件不涉及防止锯链损坏的保护。注:单独的标准ISO 21876解决了链锯损坏的危险。

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.As the tests in the document are dependent upon the mass, velocity, and the cutting or grinding element profile, the TOG meeting the requirements of this document are specific to each cutting or grinding attachment and the host machine model.This document does not address protection from saw chain shot.NOTE A separate standard ISO 21876 addresses saw chain shot hazards.
