This International Standard establishes a consistent and reproducible means of evaluating the load-carrying characteristics of Roll-Over Protective Structures (ROPS) under static loading, and prescribes performance requirements for a representative specimen under such loading.It applies to the following seated design operator-controlled machines as defined in ISO 6165:- crawler tractors and loaders; - graders; - wheeled loaders and wheeled tractors and their modified versions used for rolling or compacting, dozer-equipped wheeled tractors, skid-steer loaders and backhoe loaders;- wheeled industrial tractors; - the tractor portion (prime mover), of tractor scrapers, water wagons, articulated steer dumpers, bottom-dump wagons, side-dump wagons, rear-dump wagons and towed fifth-wheel attachments;- rollers and compactors;- rigid frame dumpers.
