ISO 9902-3:2001/Amd 1:2009

Overview

ISO 9902-3:2001/Amd 1:2009 is an international standard published by the International Organization for Standardization (ISO) that serves as an amendment to the original ISO 9902-3:2001. This document specifically addresses the noise test code for nonwoven textile machinery, enhancing guidelines to effectively measure and assess noise emissions in this sector of the textile industry. As part of the broader ISO 9902 series covering textile machinery noise testing, this amendment aligns the procedures with updated common requirements and references to other related standards.

Key Topics

• Noise Measurement Code: Provides precise methods for testing noise generated by nonwoven machinery to ensure compliance with industry noise level regulations and minimize operational impact.
• Amendment Highlights:
  • Updates normative references by removing publication years for certain ISO standards, emphasizing the most current applicable versions.
  • Incorporates ISO 9902-1 amendment for common requirements, ensuring consistency across all textile machinery noise tests.
  • Revises clauses related to measurement methodology and reporting requirements to reflect updated procedures.
• Standardized Reporting: Specifies the information to be included in noise test reports, promoting transparency and uniformity in documentation.
• Cross-Reference to Related Standards: Aligns with ISO 3744, ISO 3746, ISO 3747 (acoustic measurement techniques), and ISO 9614 series (sound intensity determination), among others.

Applications

ISO 9902-3:2001/Amd 1:2009 is essential for manufacturers, testing laboratories, and regulatory bodies involved in the production and operation of nonwoven textile machinery. Practical applications include:

• Noise Compliance Testing: Enables manufacturers to assess machinery noise emissions and ensure compliance with occupational safety and environmental noise regulations.
• Product Development: Assists engineers in designing quieter nonwoven machinery by providing standardized measurement protocols.
• Workplace Safety: Helps companies maintain safe noise exposure levels for workers in textile plants.
• Quality Assurance: Serves as a benchmark for consistent noise level evaluations across different machines and facilities.
• Regulatory Certification: Supports conformity assessments needed for machinery market access in regions with noise emission requirements.

Related Standards

This amendment to ISO 9902-3 is part of a comprehensive noise test code suite for textile machinery and relates closely to the following standards:

• ISO 9902-1:2001/Amd 1:2009 – General and common requirements for noise testing of textile machinery.
• ISO 3744, ISO 3746, ISO 3747 – Methods for determining sound power levels and sound pressure levels using various acoustic measurement techniques.
• ISO 9614-1 and ISO 9614-2 – Standards specifying sound intensity measurement methods.
• ISO 11201, ISO 11202, ISO 11204 – Standards covering sound pressure evaluation in working environments.
• ISO 9902 series – Overall noise test codes for various types of textile machinery ensuring coherence in testing methods across different machinery categories.

Utilizing ISO 9902-3:2001/Amd 1:2009 helps the textile industry establish reliable and repeatable noise measurement practices specifically tuned for nonwoven machinery. This not only supports regulatory compliance but also fosters safer and more sustainable manufacturing environments.
