ISO 9902-5:2001/Amd 2:2014

Overview

ISO 9902-5:2001/Amd 2:2014 is an important international standard published by the International Organization for Standardization (ISO) that addresses noise testing methods for textile machinery. Specifically, this amendment pertains to Part 5: Weaving and Knitting Preparatory Machinery, providing updated guidelines to measure and evaluate noise emissions in this category of machinery. The document reflects ISO’s commitment to enhancing workplace safety and environmental compliance by setting standardized noise test codes that help manufacturers and operators manage noise levels effectively.

As part of the broader ISO 9902 series devoted to textile machinery noise testing, this amendment ensures more practical and applicable testing procedures for preparatory machinery used in weaving and knitting processes.

Key Topics

• Noise Test Code for Textile Machinery: Establishes test methods for measuring sound emissions generated by weaving and knitting preparatory machinery.
• Application to Preparatory Machinery: Focuses specifically on machines that prepare fibers, yarns, or fabrics before weaving or knitting operations.
• Measurement Conditions: Highlights the complexity and high requirements for accurate noise measurement, noting the impracticality of grade 1 methods for textile machinery due to environmental and operational constraints.
• ISO/IEC Directives Compliance: Drafted following the editorial and procedural rules of ISO/IEC Directives Part 1 and 2 to ensure consistency, transparency, and international consensus.
• Safety and Environmental Impact: Helps ensure compliance with occupational health regulations and supports noise control efforts in textile manufacturing environments.

Applications

• Textile Machinery Manufacturers: Enables manufacturers to design machinery compliant with internationally recognized noise limits, improving market acceptance and safety standards.
• Workplace Safety Management: Assists occupational health professionals in assessing potential noise hazards in textile production areas to protect worker hearing and wellbeing.
• Regulatory Compliance: Supports textile industries in meeting national and international noise regulations, reducing the risk of legal penalties or operational restrictions.
• Product Development and Testing: Provides standardized testing methods that facilitate reproducible sound emission measurements during machinery development and quality control.
• Environmental Noise Control: Helps reduce noise pollution caused by textile preparatory machinery, contributing to better working environments and community relations.

Related Standards

• ISO 9902 Series: Covers noise test codes for various categories of textile machinery, outlining consistent noise measurement methods across the industry.
• ISO/TC 72: The technical committee responsible for textile machinery and accessories, which oversees standards including safety and noise-related requirements.
• ISO/IEC Directives Parts 1 and 2: Documents that define the procedural and editorial rules for developing and maintaining ISO standards.
• Occupational Noise Standards: National and international guidelines related to permissible noise exposure in industrial settings, often used alongside ISO testing methods for comprehensive noise management.
• International Electrotechnical Commission (IEC) Collaboration: ISO works closely with IEC to harmonize standards related to electromechanical aspects of textile machinery, including noise emissions.

By adhering to ISO 9902-5:2001/Amd 2:2014, stakeholders in the textile industry can ensure robust noise assessment practices for weaving and knitting preparatory machinery, ultimately improving safety, compliance, and operational performance across global markets.
