ISO 9902-1:2001/Amd 2:2014

Overview

ISO 9902-1:2001/Amd 2:2014 is an important amendment to the international standard governing noise testing for textile machinery. Issued by the International Organization for Standardization (ISO), this document updates Part 1 of the noise test code titled "Common Requirements." It provides essential guidance on how to measure and assess the acoustic emissions of textile machinery, ensuring safety, regulatory compliance, and improved operational environments.

This amendment recognizes that due to the stringent measurement conditions, Class 1 methods-typically used for general noise measurement-are not usually suitable for textile machines. The updated requirements aim to standardize noise testing processes across the textile industry with practical, reliable methods adapted to the specific challenges of textile equipment.

Key Topics

• Noise Test Code for Textile Machinery: Establishes a framework for evaluating sound emissions from various textile machines to promote occupational safety and environmental considerations.
• Common Requirements: Defines the general conditions and protocols for acoustic testing applicable to all textile machinery categories.
• Measurement Method Limitations: Highlights that Class 1 noise measurement methods, which require highly controlled environments, are generally impractical for textile machinery noise testing.
• Stringent Measurement Conditions: Emphasizes the need for realistic yet rigorous measurement procedures tailored specifically to the acoustic characteristics of textile equipment.
• ISO/TC 72 Committee: Developed under the technical committee responsible for textile machinery and safety standards, ensuring specialized expertise integrates into the noise assessment protocols.

Applications

ISO 9902-1:2001/Amd 2:2014 has practical value for manufacturers, safety engineers, and regulatory bodies involved in the textile industry:

• Manufacturers can implement the standard to design quieter machinery, ensuring compliance with occupational noise regulations and enhancing user comfort.
• Safety Inspectors use this standard to accurately assess workplace noise exposure in textile factories, helping to mitigate hearing loss risks to workers.
• Regulatory Compliance: The updated noise measurement guidelines facilitate adherence to international noise limits and environmental noise reduction policies.
• Quality Assurance: Consistent noise testing improves product quality and minimizes noise-related complaints from end-users.
• Research and Development: Provides a benchmark to innovate quieter machinery by enabling reliable noise data collection during prototype testing.

Related Standards

For holistic noise management in textile machinery and related industrial contexts, it is helpful to consider the following associated standards:

• ISO 9614 Series – For determining sound power levels from noise sources using sound intensity methods.
• ISO 11201 – Guidelines for noise measurement conditions in workspaces.
• ISO 1996 – Acoustics – Description, measurement, and assessment of environmental noise.
• ISO 9001 – Supports quality management systems that can integrate noise control as part of overall equipment manufacturing.
• ISO/IEC Directives – Provide procedural guidance for drafting and updating ISO standards, referenced in the amendment’s preparation.

By adhering to ISO 9902-1:2001/Amd 2:2014, stakeholders in the textile machinery sector can ensure accurate, practical noise testing that aligns with international best practices, ultimately promoting workplace safety and environmental responsibility.
