scope:

This Standard specifies a) the laboratory tests for measurement of structural characteristics, and b) the performance requirements in a representative test, of a falling-object protective structure (FOPS). The laboratory tests are a means of testing the characteristics of the structures used to protect the operator from localized impact penetration and, indirectly, of the load-carrying capacity of the supporting structure to resist impact loading. This Standard establishes a consistent, repeatable means of evaluating characteristics of FOPS under loading and prescribes performance requirements for these structures under such loading in a representative test. This Standard applies to the following types of operator-controlled machines, regardless of the type of steering system used, as defined in ISO 6165: - crawler loaders, wheel loaders and backhoe loaders; - crawler tractors and wheel tractors; - graders; -tractor-scrapers.
