Overview
EN ISO 9902-2:2001/A1:2009 is an amendment to the international standard concerning noise testing for textile machinery, specifically focusing on spinning preparatory and spinning machines. Issued by CEN in collaboration with ISO/TC 72 and CEN/TC 214, this document updates Part 2 of the Textile Machinery Noise Test Code - a vital reference for manufacturers and testing bodies involved in noise emission assessment within the textile industry. The amendment aligns the standard with the revised Part 1 (ISO 9902-1:2009), ensuring consistent and up-to-date noise measurement protocols.
This noise test code standard establishes methods to measure, assess, and report airborne noise emitted by textile spinning machinery, providing stakeholders with a clear framework to comply with regulatory requirements and improve workplace safety.
Key Topics
-
Scope of Machinery: The standard specifically addresses noise measurement procedures for spinning preparatory and spinning machinery - including carding, combing, and spinning equipment used in textile production.
-
Noise Test Code: Defines the methodological approach to perform airborne noise emission tests, essential for evaluating machinery performance and environmental impact.
-
Amendment Focus: The 2009 amendment mainly revises references to the common requirements in ISO 9902-1:2009, replacing prior mentions of the 2001 edition. This update affects multiple clauses and ensures harmonization with the latest procedural standards.
-
Compliance with EU Directives: The standard supports conformity with essential requirements of the EU Machinery Directive 2006/42/EC and prior directives like 98/37/EC. Compliance with EN ISO 9902-2 helps manufacturers demonstrate product adherence to relevant safety and noise emission regulations.
-
International Collaboration: Developed under the Vienna Agreement between ISO and CEN, the document ensures wide acceptance and implementation across European and international textile machinery manufacturers.
Applications
-
Noise Emission Testing: Manufacturers use this standard to conduct standardized noise tests on spinning preparatory and spinning machines to quantify noise levels during operation.
-
Product Development: Engineering teams apply guidelines in designing quieter machinery, thereby reducing noise pollution in textile manufacturing facilities and improving worker hearing safety.
-
Regulatory Compliance: Meeting noise emission limits is critical to fulfilling legislative and environmental regulations, particularly within the European Union. This standard offers a path to achieving verified compliance and certification.
-
Workplace Health and Safety: Ensuring machinery noise levels conform to tested limits helps protect personnel from harmful occupational noise exposure, enhancing overall workplace environment quality.
-
Quality Control and Benchmarking: Serves as a tool for benchmarking machinery noise performance between different product lines, improving noise management practices within organizations.
