ISO 9902-5:2001/Amd 1:2009

Overview

ISO 9902-5:2001/Amd 1:2009 is an important amendment to the ISO 9902-5:2001 standard titled Textile machinery - Noise test code - Part 5: Weaving and knitting preparatory machinery. Published by the International Organization for Standardization (ISO), this document serves to update and enhance the noise testing code specifically for preparatory machines used in weaving and knitting processes within the textile industry.

The amendment aligns Part 5 with the general requirements set forth in ISO 9902-1:2001 and its subsequent amendment, ensuring consistency and harmonization across the noise test codes applied to various types of textile machinery. This standard focuses on providing methods for assessing noise emissions, promoting workplace safety, and supporting regulatory compliance related to occupational noise exposure.

Key Topics

• Noise Test Code Updates
  ISO 9902-5:2001/Amd 1:2009 revises normative references by removing publication years and integrating the latest amendments to Part 1 (common requirements), improving cross-referencing and methodological clarity for noise measurements.

• Harmonization with ISO 9902-1
  Several clauses and normative references now direct users to the updated requirements in ISO 9902-1:2001/Amd 1:2009, promoting standardization across all parts of the noise test code series.

• Scope Focus on Preparatory Machinery
  The amendment pertains exclusively to weaving and knitting preparatory machinery, which includes equipment involved in preparing yarns before the weaving or knitting process. Accurate noise level assessment in these machines ensures better noise control and worker protection.

• Normative References
  The document updates references to other ISO standards related to acoustic testing methods (such as ISO 2544, ISO 3744 series, ISO 9614 series, and ISO 11201 series) without specific publication years, reflecting the most current and relevant testing techniques.

Applications

• Industrial Textile Manufacturing
  Manufacturers of textile machinery use this standard to conduct noise emission tests on weaving and knitting preparatory equipment, ensuring compliance with international safety and environmental regulations.

• Occupational Health and Safety
  Businesses implement ISO 9902-5 noise test procedures to assess and control noise exposure in textile factories, thereby protecting workers’ hearing and improving workplace conditions.

• Product Certification and Market Access
  Adhering to this amendment helps machinery producers achieve certification required by global markets, facilitating trade and acceptance of their products internationally.

• Research and Development
  Designers and engineers leverage the updated noise measurement methods to develop quieter textiles machinery, supporting innovation in ergonomic and environmentally sustainable manufacturing.

Related Standards

• ISO 9902-1:2001/Amd.1:2009 - Textile machinery noise test code common requirements. This standard sets the fundamental principles adopted by Part 5 amendment to ensure uniform noise testing practices.

• ISO 2544 & ISO 3744 Series - Methods for noise measurement and determination of sound power levels, key references for performing accurate acoustic assessments.

• ISO 9614-1 and ISO 9614-2 - Sound intensity measurement standards used to evaluate noise sources on machinery surfaces.

• ISO 11201, ISO 11202, and ISO 11204 - Standards covering environmental noise measurement techniques, essential for assessing workplace noise exposure risks.

By incorporating ISO 9902-5:2001/Amd 1:2009, stakeholders in the textile machinery sector can ensure reliable noise assessment, contribute to sustainable manufacturing practices, and uphold worker safety through internationally recognized acoustic testing protocols.
