scope:

This part of ISO 12117 establishes a consistent and reproducible means of evaluating the load-carrying characteristics of roll-over protective structures (ROPS) for excavators under static loading, and prescribes performance requirements of a representative specimen under such loading. It applies to ROPS of hydraulic excavators as defined in ISO 6165 with a mass of over 6 t and less than 50 t. ROPS will ensure minimum crush protection space for a seat-belted operator when the machine rolls 360° about longitudinal axis of its revolving frames without losing contact with a hard clay slope of less than 30°. ROPS is to be applied where the risk of roll-over exists. It also applies to ROPS for excavator-based or derivated excavators used in object or material handling, demolition or with attachments such as magnets, clamshell, grab or multi-claw grab. It does not apply to excavators with elevating cab risers.
