林业机械.防锯齿脱落的驾驶室围墙所用墙玻璃材料和面板材料.试验方法和性能标准

[中文适用范围]： 本文件规定了投掷物防护装置 (TOG) 的实验室测试方法和性能要求，为操作员提供针对投掷物的保护。 这适用于林业和相关作业中使用的移动式和自走式机械，包括但不限于由动力旋转切割或研磨元件以及主机上的附件抛出的残留物定义的机械。 由于本文件中的测试取决于质量、速度以及切割或磨削元件轮廓，因此满足本文件要求的 TOG 特定于每个切割或磨削附件和主机型号。 本文件不涉及锯链射击的防护。 注：单独的标准 ISO 21876 解决了锯链射击危险。 [外文原描述]： 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.
