1.范围1。1本标准提供了评估静态载荷下防滚翻保护结构（ROPS）的力、挠度和能量吸收特性的方法。本标准适用于工业拖拉机、平地机、原动机、集材机、履带式推土机、履带式装载机、轮式推土机、轮式装载机、反铲装载机、刚架自卸车、压实机和机器质量大于700 kg的压路机的ROPS测试。注:通用工业拖拉机可根据本标准或CSA标准B352的要求进行评估。1.1.2满足国际标准ISO 3471/1或SAE标准J1040 1988年4月要求的操作也满足本标准的要求，前提是CSA标准B352第4条中规定的一般要求。也满足0。1.3尽管由于设计或使用原因，一些机器不容易发生纵向翻转，但机器的形状和重心位置可能会在横向翻转期间导致相对于斜坡的倾斜。 横向侧翻时的机器前进速度也可能施加纵向载荷。就其性质而言，其他机器会受到纵向翻转的影响。因此，本标准规定了在所有机器上测试ROPS的纵向力标准。1.4本标准中使用的术语定义见CSA标准B352。0

1. Scope1.1This Standard provides methods for evaluating the force, deflection, and energy-absorption characteristics of rollover protective structures (ROPS) under static loading. This Standard applies to the testing of ROPS on industrial tractors, motor graders, prime movers, skidders, tracked dozers, tracked loade rs, wheeled dozers, wheeled loaders, backhoe loaders, rigid-frame dumpers, compactors, and rollers with a machine mass greater than 700 kg. Note: General purpose industrial tractors may be evaluated according to the requirements of either this Standard or CSA Standard B352.1.1.2ROPS meeting the requirements of International Standard ISO 3471/1 or SAE Standard J1040 APR 88 also meet the requirements of t his Standard, provided the general requirements as specified in Clause 4 of CSA Standard B352.0 are also met.1.3Although some machines, because of design or use, are not prone to longitudinal upset, machine shape and location of the centre of gravity may cause skewing relative to a slope during lateral rollover. Machine forward velocity at the time of lateral rollover may also impose a longitudinal load. Other machines, by their nature, are subject to longitudinal upset.This Standard therefore sets longitudinal-force criteria for testing ROPS on all machines.1.4Definitions of terms used in this Standard are found in CSA Standard B352.0.
