1. Scope
1.1
This Standard is a companion to the other Standards of the B352 series and can only be used in conjunction with each of the Standards.
1.2
This series of Standards details the design, testing, performance, and safety requirements for rollover protective struct ures (ROPS) for certain types of self-propelled machines for agricultural, construction, earthmoving, forestry, industrial, and mining operations, as listed in Clauses 1.3, 1.4, and 1.5.
1.3
CSA Standard B352.1 covers the performance requirements, based on destructive testing, for ROPS on wheeled agricultural tractors with a mass greater than 800 kg. It may also be used as an alternative method for testing ROPS on general-purpose industrial tractors.
1.4
CSA Standard B352.2 covers the performance requirements, based on destructive testing, for ROPS on industrial tractors, motor graders, prime movers, skidders, tracked dozers, tracked loaders, wheeled dozers, wheeled loaders, backhoe loaders, rigid-frame dumpers, compactors, or rollers, with machine mass greater than 700 kg.
1.5
CSA Standard B352 may continue to be used for developing and testing ROPS on machines not covered by either CSA Standards B352.1 or B352.2, such as ROPS for small, specialized agricultural tractors. As well, Clause 6 of B352 should be used for analytical design of one-of-a-kind machines until revised analytical guidelines are developed.
1.6
The testing of ROPS aims at minimizing the likelihood of operator injury resulting from accidental overturning during normal operation. Although ROPS meeting the requirements of this series of Standards may not provide crush protection under all circumstances of machine overturn, it is expected that protection will be provided for an operator wearing a seatbelt under at least the following conditions: (a) a 360? roll about the machine's longitudinal axis on a hard clay surface of 30? maximum slope, at forward speeds up to 16 km/h, when not losing contact with the slope; and (b) a 180? rear or frontal overturn on a hard dry surface, without losing contact with the surface.
