ISO 9902-7:2001/Amd 2:2014

Overview

ISO 9902-7:2001/Amd 2:2014 is an important amendment to the international standard that defines the noise test code specifically for dyeing and finishing textile machinery. Published by the International Organization for Standardization (ISO), this update refines the noise measurement procedures to ensure more accurate and practical assessment of acoustic emissions produced by textile dyeing and finishing machines.

This standard addresses critical environmental and occupational health concerns by providing a unified methodology to evaluate noise levels. It supports machinery manufacturers, operators, and regulatory bodies in maintaining safe and compliant working environments while minimizing noise pollution associated with textile processing.

Key Topics

• Noise Test Code for Textile Machinery
  ISO 9902-7:2001 focuses on establishing stringent noise measurement protocols tailored for dyeing and finishing machines used in the textile industry.

• Amendment 2 Updates
  The 2014 amendment introduces clarifications and additional notes emphasizing the challenges in applying grade 1 measurement methods universally to textile machinery due to practical constraints.

• Measurement Conditions
  It highlights the necessity for controlled measurement environments as high precision noise measurement conditions are difficult to meet in typical industrial settings. This ensures reliable and repeatable test results.

• ISO/TC 72 and SC 8 Oversight
  The standard is maintained by ISO technical committee ISO/TC 72, subcommittee SC 8, which specializes in the safety requirements for textile machinery.

Applications

• Textile Machinery Manufacturers
  Manufacturers use this standard to design and test dyeing and finishing machinery that meet internationally recognized noise emission limits, improving product compliance and market acceptance.

• Workplace Safety Compliance
  Companies operating dyeing and finishing equipment can assess noise exposure to ensure compliance with occupational health standards and reduce risks of hearing damage to workers.

• Environmental Noise Control
  Standardized noise testing helps in benchmarking and controlling noise pollution originating from textile processing plants, contributing to better industrial environmental management.

• Quality Assurance and Certification
  The noise test code serves as an essential tool for quality assurance processes, enabling certification and validation of machinery according to ISO noise emission requirements.

Related Standards

• ISO 9902 Series
  Other parts of ISO 9902 cover noise test codes for various types of textile machinery, providing a comprehensive framework for noise assessment across textile manufacturing equipment.

• ISO/IEC Directives Part 1 & 2
  These directives outline the editorial rules and development procedures followed in drafting and maintaining ISO standards, ensuring consistency and transparency.

• Occupational Noise Standards
  Relevant standards on workplace noise exposure limits, such as those published by ISO or other regional bodies, complement ISO 9902-7 by addressing human health considerations.

• ISO/TC 72 Standards on Textile Machinery Safety
  Related safety requirements specified by ISO/TC 72 subcommittees help ensure overall operational safety beyond noise emission control.

By adhering to ISO 9902-7:2001/Amd 2:2014, stakeholders in the textile industry benefit from an internationally recognized method for assessing and controlling noise emissions of dyeing and finishing machinery, contributing to safer workplaces and improved environmental outcomes.
