工程机械用农用轮胎

[中文适用范围]： 本文件规定了在建筑工地装载和运输条件下工作的工程机械（例如反铲装载机、小型自卸车、装载机、挖掘机）所配农业轮胎的名称、尺寸、核准轮辋轮廓、额定载荷和参考速度。符合本文件的轮胎在轮胎尺寸名称中以后缀 IND 标识；代码指定的轮胎也可以用分类代码 R-4 代替后缀 IND 标识。注意：轮胎尺寸名称中没有后缀 IND 或分类代码不同于“R-4”的农业轮胎不属于本文件。用于农业拖拉机、拖车和机器的代码指定的斜交轮胎（帘布层级标记系列）是 ISO 4251-1 和 ISO 4251-2 的一部分。农业拖拉机、拖车和机械用代码指定的子午线轮胎属于 ISO 8664 标准。农业拖拉机、拖车和机械用公制指定的轮胎属于 ISO 7867-2 标准。林业机械用轮胎（后缀 LS 或分类代码 LS-x）属于 ISO 18807 标准。 [外文原描述]： This document specifies the designation, dimensions, approved rim contours, load ratings and reference speeds for agricultural tyres fitted to construction machines (e.g. backhoe loaders, small dumpers, loaders, excavators) operating on building sites under loading and transport conditions. Tyres conforming to this document are identified by the suffix IND in the tyre size designation; code designated tyres can alternatively, in place of the suffix IND, be identified by the classification code R-4. NOTE Agricultural tyres without the suffix IND in the tyre size designation or with a classification code differing from "R-4" are not part of this document. Code designated diagonal tyres (ply rating marked series) for agricultural tractors, trailers and machines are part of ISO 4251-1 and ISO 4251-2. Code designated radial tyres for agricultural tractors, trailers and machines are part of ISO 8664. Metric designated tyres for agricultural tractors, trailers and machines are part of ISO 7867-2. Tyres for forestry machines, identified by suffix LS, or classification code LS-x are part of ISO 18807.
