Abstract：[Objective]This studyproposes revisions tothenational standard GB/T3487-2017，Hydraulicfluid powerTest code for the determinationof noise levelof hydraulicmotors.[Methods]The proposed revisions include： updating terminology and definitions； introducing acuboid measurement surface test environment； adding supplementary noise measurement points ona hemisphericalmeasurement surface； correcting formulas for A-weighted average sound pressure level and sound power level； updating the permissible system eror specifications for measuring instruments； and reevaluating background noise correctionvalues.[Results]Theresults showthattheserevisions addressproblems such as deficiencies interminologydefinitions andambiguities indatacolection methods inthecurrent standard.They broaden the standard's scope of application，enhance measurement accuracy， and improve the reliability and consistency of testesults.[Conclusion]Therevisionofthe standardwillprovideclearer guidance forthedesign，manufacturing，and application of low-noise hydraulic motors， contributing to the industry's green and sustainable development.

Keywords：hydraulicmotors，noisemeasurement，cuboid measurement surface，hemisphericalmeasurementsurface， sound pressure level， sound power level
