ISO 9902-2:2001/Amd 1:2009

Overview

ISO 9902-2:2001/Amd 1:2009 is an essential amendment to the international standard focusing on noise testing codes specifically for spinning preparatory and spinning machinery within the textile industry. Published by ISO, this amendment updates Part 2 of ISO 9902-2:2001, aligning noise measurement procedures and normative references with current technical requirements. It ensures the accuracy and consistency of noise emission assessments crucial for machinery safety, operator health, and compliance with environmental regulations.

Key Topics

• Noise Test Code for Textile Machinery: This standard provides guidance on measuring acoustic emissions from spinning preparatory and spinning machinery, which are critical components in textile manufacturing.
• Normative References Update: Key ISO standards related to acoustics (such as ISO 3744, ISO 11201, and ISO 9614 series) have had their publication years removed to allow for future revisions without needing immediate standard amendments.
• Integration with Part 1: The amendment references ISO 9902-1:2001/Amd.1:2009 to ensure consistency in common noise test requirements across all textile machinery categories.
• Large Machinery Designation: Introduction of a designation “L” for very large machines within the standard’s tables, enhancing classification clarity for noise testing procedures.
• Technical Committee Involvement: Developed by ISO/TC 72, specifically SC 8, which focuses on safety requirements for textile machinery, reflecting expert consensus and industry needs.

Applications

ISO 9902-2:2001/Amd 1:2009 is vital for:

• Textile Manufacturers: Ensures that noise levels of spinning preparatory and spinning machinery comply with international standards, promoting safer work environments and reducing noise pollution.
• Machinery Designers and Engineers: Assists in the design and testing phases by providing precise noise measurement protocols to meet regulatory and safety requirements.
• Health and Safety Regulators: Facilitates the enforcement of occupational noise limits to prevent hearing loss among workers in the textile sector.
• Certification Bodies and Testing Laboratories: Provides standardized testing methods that enable accurate measurement, certification, and comparison of machinery noise levels.

Related Standards

• ISO 9902-1:2001/Amd.1:2009: Covers common requirements for noise testing across different textile machinery types, supplementing Part 2 with general principles and test methods.
• ISO 3744 and ISO 3746: Define engineering methods for noise emission determination based on sound power levels.
• ISO 9614-1 and ISO 9614-2: Specify sound intensity measurement techniques applicable to machine noise analysis.
• ISO 11201, ISO 11202, ISO 11204: Address measurement of noise emissions in workplaces, including directivity and tonality assessments relevant to textile machinery noise.
• ISO 2187: Provides methods to analyze noise in specialized conditions, supporting comprehensive acoustic evaluations.

By complying with ISO 9902-2:2001/Amd 1:2009, organizations can ensure their spinning preparatory and spinning machinery adheres to up-to-date international noise testing standards, enhancing operational safety, minimizing environmental noise impact, and promoting sustainable manufacturing practices in the textile industry.
