SAE J 1446:2003 PDF Download

The SAE J 1446:2003 standard is a set of procedures that outline the test and evaluation process for on-machine alarms used in construction and general-purpose industrial machinery. The standard specifically focuses on evaluating alarms on off-road self-propelled work machines while they are in a stationary, parked position.

The purpose of this standard is to establish criteria and procedures that are necessary for qualifying an audible alarm when mounted on these types of machines. The alarm's primary function is to provide a warning to personnel of potential hazards, particularly when the machine is moving in reverse under its own power. The standard aims to ensure that the alarm's design, condition, voltage, and placement on the machine are all factors that contribute to its proper performance.

It is worth noting that this standard is similar to ISO/DIS 9533, which is a sound test method for machine-mounted forward and reverse warning alarms on earthmoving machinery. However, SAE J 1446 specifically focuses on construction and general-purpose industrial machinery as defined by SAE J1116 JUN86. The ultimate goal of this standard is to ensure that the audible alarm on these machines effectively warns personnel without causing undue discomfort or irritation to the operator.
