Abstract
Overview
ISO 4412-2:1991 - Hydraulic fluid power - Test code for determination of airborne noise levels - Part 2: Motors - defines a standardized test code to determine . Based on , it specifies measurement objectives, instrumentation, installation and operating conditions, measurement points and test procedures so that results are repeatable and comparable. The part applies to all types of hydraulic fluid power motors operating in steady state (practical limitation: motors above 50 r/min) and includes informational annexes (C: application guidelines; D: bibliography).
