ISO 9902-1:2001/Amd 1:2009

Overview

ISO 9902-1:2001/Amd 1:2009 is an international standard amendment focusing on textile machinery and its associated noise test code. Part 1 outlines the common requirements for conducting noise emission tests on textile machinery, helping manufacturers, suppliers, and facility managers assess compliance with health, safety, and environmental regulations. This amendment updates and clarifies several procedural and normative reference points in the base 2001 standard. Developed by the International Organization for Standardization (ISO), this amendment ensures better alignment with related standards, particularly ISO 11111 for textile machinery safety requirements.

Key Topics

• Scope Extension: The amendment clarifies that ISO 9902-1 applies to all textile machinery, plants, and equipment described in ISO 11111 (all parts), including automated machinery and process equipment, but excluding material transport between machines.
• Normative References Updates: References to various ISO standards dealing with acoustics and sound measurement methods are standardized by removing publication years and updating textual references.
• Terminology Adjustments: Notes adapted from ISO 3740 are integrated to maintain consistency in sound measurement definitions across standards.
• Sound Measurement for Large Machines: For particularly large textile machines, only emission sound pressure levels (not sound power levels) are required, streamlining testing procedures. Such machines are denoted by "L" in related tables.
• Reporting Requirements: The amendment reinforces that information about airborne noise emissions must be present in a machine’s documentation, referencing ISO 12100-2 for safety-related declarations.
• Document Structure Adjustments: Edits to annexes streamline noise standard footnotes and clarify references to relevant terminology in ISO 3744 and ISO 3746.

Applications

ISO 9902-1:2001/Amd 1:2009 is highly relevant across the textile machinery industry for:

• Manufacturers of Textile Machinery: Ensures new machinery meets up-to-date noise emission requirements, supporting global market access and compliance with buyer specifications.
• Quality and Compliance Managers: Provides a clear framework for verifying that equipment manuals and documentation properly report noise emissions.
• Engineering and Safety Professionals: Assists in carrying out consistent and valid noise emission tests, especially on large machinery where only sound pressure levels must be measured.
• Standardization of Automated Systems: Promotes the safe rollout of automated equipment by ensuring consistent noise test criteria.

This amendment is integral for achieving and maintaining compliance with both safety and environmental standards in textile manufacturing environments. By referencing the latest requirements and aligning terminology and procedures, organizations can more efficiently demonstrate their commitment to operator safety and workplace environmental standards.

Related Standards

• ISO 11111 (All Parts): Safety requirements for textile machinery, closely integrated with this noise test code amendment.
• ISO 3740, ISO 3743-1, ISO 3747: Methods for the determination of sound power levels for noise sources, cited for measurement procedures.
• ISO 3744:1994, ISO 3746:1995: Key standards for acoustic terminology and measurement techniques.
• ISO 12100-2: Safety principles for machinery, especially regarding the declaration of noise emissions in technical documentation.
• Other ISO 9902 Parts: Address noise measurement for specific types of textile machinery and further expand on testing methodologies referenced in Part 1.

By staying current with ISO 9902-1:2001/Amd 1:2009, stakeholders in the textile machinery sector ensure their products and operations conform to internationally recognized noise emission and documentation requirements, helping create safer, healthier working environments and supporting international trade.
