SAE J 1119:2013 PDF Download

The SAE J 1119:2013 standard provides concepts and guidelines for the selection and application of materials for ROPS and FOPS. The standard specifically focuses on steel as the material of choice for these structures, considering its mechanical properties and processing characteristics.

The emphasis in this standard is on the toughness of the steel, which refers to its ability to resist brittle fracture. This property is deemed crucial for ensuring the integrity of the protective structures. However, the report acknowledges that the specific values of material properties are only relevant when taken into account with other design considerations, such as the size of the structure or the details and location of weld joints.

It is important to note that while steel is the preferred material, the standard acknowledges that other materials could potentially be used successfully for ROPS and FOPS. The report does not make definitive recommendations for selecting steels, as there are numerous design-material systems that can meet the required performance standards for these protective structures.
