This International Standard establishes a consistent, reproducible means of evaluating the forcedeflection characteristics of rollover protective structures (ROPS) on selfpropelled forestry machines under static loading, and prescribes performance requirements for a representative specimen under such loading. It is applicable to forwarders, skidders, feller-bunchers, processors, harvesters and loaders, as defined in ISO 6814. It is not applicable to machines having a rotating platform with a cab and boom on the platform. NOTE Research work is being done to develop a test method and criteria for machines having a rotating platform with a cab and boom on the platform. These machines are to be included in a future revision of ISO 8082.
