1.范围1。1本标准提供了基于破坏性试验评估质量大于800 kg的轮式农业拖拉机防滚翻结构（ROPS）性能的方法。它也可用作CSA标准B352的替代品。2用于在通用工业拖拉机上测试ROPS。1.2符合国际标准ISO 5700（静态试验）或ISO 3463（动态试验）或SAE标准2194要求的操作也符合本标准的要求，前提是CSA标准B352中规定的一般要求。 也满足0。1.3在给出的两个试验选项中，动态试验仅适用于质量在800到6000 kg之间的拖拉机，而静态试验可用于质量在800到15000 kg之间的拖拉机。静态试验也可临时用于质量大于15 000 kg的拖拉机，直到获得开发本标准新版（质量限值增加）的经验为止。1.4根据本标准测试的拖拉机后轮的最小轮距应大于1150 mm。 一般认为，本标准可能不适用于某些拖拉机设计（例如，草坪拖拉机、狭窄葡萄园拖拉机、用于低矮建筑的薄型拖拉机、果园拖拉机、高跷拖拉机和某些林业拖拉机）。本标准或CSA标准B352可临时用于此类拖拉机，直到制定适当的标准。1.5本标准中使用的术语定义见CSA标准rd B352。0

1. Scope1.1This Standard provides methods for evaluating the performance, based on destructive testing, of rollover protec tive structures (ROPS) for wheeled agricultural tractors with a mass greater than 800 kg. It may also be used as an alternative to CSA Standard B352.2 for testing ROPS on general- purpose industrial tractors.1.2ROPS meeting the requirements of International Standard ISO 5700 (static test) or ISO 3463 (dynamic test) or SAE Standard 2194 also meet the requirements of this Standard, provided the general requirements as specified in CSA Standard B352.0 are also met.1.3Of the two test options presented, the dynamic test applies only to tractors with mass ranging from 800 to 6000 kg, while the static test may be used for tractors with mass from 800 to 15000 kg. The static test may, also, be used on an interim basis for tractors with mass greater than 15 000 kg until such time that experience is gained for development of a new edition of this Standard with increased mass limits.1.4The minimum track width of the rear wheels of tractors tested according to this standard should be greater than 1150 mm. It is recognized that there are tractor designs (eg, lawn tractors, narrow vineyard tractors, low-profile tractors used in low buildings, orchard tractors, stilt tractors, and certain forestry tractors) for which this Standard may not be appropriate. This Standard or CSA Standard B352 may be used on an interim basis for such tractors until appropriate Standards are developed.1.5Definitions of terms used in this Standard are given in CSA Standa rd B352.0.
