Overview
The EN ISO 9902-4:2001/A1:2009 standard, titled "Textile machinery - Noise test code - Part 4: Yarn processing, cordage and rope manufacturing machinery - Amendment 1", is a critical amendment focused on noise measurement and evaluation procedures for textile machinery involved in yarn processing, cordage, and rope manufacturing. Developed through a collaborative effort between ISO/TC 72 and CEN/TC 214, this amendment refines and updates the noise testing methodologies to align with the latest technical progress and regulatory requirements.
This standard ensures that noise emissions from specific textile machinery are assessed consistently and safely, supporting compliance with European machinery directives. It is an essential reference for manufacturers, engineers, and safety professionals within the textile sector aiming to control occupational noise exposure and comply with relevant EU regulations.
