J88_198503 SOUND MEASUREMENT—EARTHMOVING MACHINERY—EXTERIOR

This SAE Standard is applicable to machinery of 15 kw (20 rated bhp) and over. It is not intended to cover operation of safety devices (such as backup alarms). The sound levels obtained by using the test procedures set forth in this SAE Standard are repeatable and are representative of the higher range of sound levels generated by the machinery under actual field operating conditions, but do not necessarily represent the average sound level over a field use cycle.
