Introduction- This SAE Recommended Practice establishes the sound levels for backup alarm devices when used on construction and industrial machinery. It also establishes the equipment and procedure to be used when making such measurements.

The scope of construction and industrial machinery encompasses only mobile equipment powered by internal combustion engines and generally utilized outside factory and building areas, such as crawler tractors, dozers, loaders, power shovels and cranes, motor graders, paving machines, off-highway trucks, ditchers, trenchers, compactors, scrapers, and wagons.

In the cases of those machines which do not distinguish in direction of working travel, for example, certain compactors, the use of a backup alarm device may not be applicable.

The backup alarm shall be mounted at the rear of the equipment and be so protected or constructed as to withstand severe wear and tear, adverse weather, and unfavorable environmental working conditions.

Actuation of the alarm shall be automatic, with no disconnecting means of any kind between the source of actuation and the alarm.

The alarm shall be actuated either by rearward motion of the vehicle or by engagement of the reverse control mechanism of the vehicle, whether these two conditions occur separately or simultaneously.

The alarm shall not deactivate until rearward motion of the vehicle has ceased and the reverse control mechanism has been disengaged.
