This procedure is intended for evaluating alarms on off-road self-propelled work machines while in a stationary@ parked position. Purpose-This SAE Recommended Practice outlines the procedures and sets criteria necessary to qualify an audible alarm when mounted on off-road self-propelled work machines as defined by SAE J1116 JUN81 (limited to categories 1. Construction@ and 2. General Purpose Industrial). The purpose of an alarm is to warn personnel of a potential hazard of a machine moving in reverse under its own power@ without undue discomfort or irritation to the operator. Alarm performance on the machine is a function of alarm design@ condition@ voltage at the alarm@ and placement on the machine with respect to machine components. This procedure verifies that the combination of factors produce an audible alarm.
