ISO 9902-4:2001/Amd 1:2009 is a technical standard for textile machinery, specifically focusing on noise testing for yarn processing, cordage, and rope manufacturing equipment. It's a refinement of the original 2001 standard, with "Amd 1:2009" indicating an amendment issued in 2009 that likely includes clarifications or updates to the testing methods.
