Fulfillment of the intended purpose requires testing as follows:
A temperature-material requirmenet. This can be satisfied by using the appropriate materials or by performing any of the structural performance tests at -18 degrees C.
A laboratory test, under repeatable and controlled loading, to permit anaysis of the ROPS for compliance with the performance requirements of this document. Either the static test sequence or the impact test sequence shall be conducted.
A set belt anchorage test.
The test procedures and performance requirements outlined in this document are based on currently available engineering data.
The purpose of this document is to establish the test and performance requirements of a roll-over protective structure (ROPS), designed for wheeled agricultural tractors to minimize the frequency and severity of operator injury resulting from accidental tractor upset.
