- Scope
- This standard specifies: laboratory tests for measuring the characteristics of falling object protective structures (FOPS); performance requirements in typical tests of falling object protective structures (FOPS). Note: "Typical test" in this standard is a test piece test whose materials, dimensions and processing requirements are representative of the FOPS currently in production. Laboratory tests of FOPS are a means of examining the properties of such structures, which are designed to protect drivers from local impact penetration hazards, and these tests in turn indirectly test the bearing structure's resistance to impact loads ability. This standard establishes a uniform, repeatable method for qualifying the performance of FOPS under load and specifies the performance requirements for this protective structure when subjected to a standard drop weight test. This standard applies to crawler loaders, tire loaders, backhoe loaders, crawler tractors, tire tractors, motor graders and self-propelled scrapers operated by the driver. This standard does not apply to self-propelled compactors, drilling machines, pavers, machinery with a rated power of less than 15kW, belt conveyors, excavators, cranes and draglines, etc.
