ISO 3471:2008规定了土方机械金属防滚翻保护结构（ROPS）的性能要求，以及通过对代表性样本进行静态加载的实验室试验来评估是否符合这些要求的一致性和可复制的方法。 ISO 3471:2008适用于以下移动式机器的ROPS:推土机；装载机；反铲装载机；自卸车；管道工；组合式机器（如拖拉机铲运机、铰接式车架自卸车）的拖拉机部分（原动机）；平地机；垃圾填埋压实机； 滚筒挖沟机。 ISO 3471:2008不适用于培训座椅或附件操作的附加座椅。

ISO 3471:2008 specifies performance requirements for metallic roll-over protective structures (ROPS) for earth-moving machinery, as well as a consistent and reproducible means of evaluating the compliance with these requirements by laboratory testing using static loading on a representative specimen. ISO 3471:2008 is applicable to ROPS intended for the following mobile machines with seated operator as defined in ISO 6165 and with a mass greater than or equal to 700 kg: dozer; loader; backhoe loader; dumper; pipelayer; tractor section (prime mover) of a combination machine (e.g. tractor scraper, articulated frame dumper); grader; landfill compactor; roller; trencher. ISO 3471:2008 is not applicable to training seats or additional seats for operation of an attachment.
