ISO 9902-2:2001/Amd 2:2014

Overview

ISO 9902-2:2001/Amd 2:2014 is an important international standard published by ISO that addresses noise testing procedures specifically for spinning preparatory and spinning machinery used in the textile industry. This amendment updates the original 2001 standard, providing refined guidelines and clarifications to improve the accuracy and relevancy of noise measurement in textile machinery environments.

Part of the broader ISO 9902 series focused on noise test codes for textile machinery, this amendment aims to ensure consistency, reliability, and safety in noise assessment, which is vital for machinery manufacturers, operators, and regulatory bodies focused on occupational health and safety.

Key Topics

• Noise Test Code Specification
  This standard sets out methodologies for conducting precise noise measurements on spinning preparatory and spinning machines. It includes guidance on suitable measurement conditions and equipment to ensure repeatability and comparability of results.

• Measurement Conditions and Limitations
  The amendment highlights that grade 1 measurement methods, which require very strict conditions, are generally not feasible for textile machinery due to operational constraints. This practical insight helps users select appropriate testing protocols suited to real-world manufacturing environments.

• Safety and Compliance
  By following the noise test code defined in this standard, textile manufacturers can better comply with occupational noise exposure limits, reduce worker exposure to harmful sound levels, and align with international safety regulations.

• Collaboration and Standardization Process
  Developed by ISO Technical Committee 72, Subcommittee 8, the standard reflects a consensus among global experts in textile machinery safety, fostering harmonization across international markets.

Applications

• Textile Machinery Manufacturing
  Machine designers and manufacturers use this standard to evaluate the acoustic performance of spinning preparatory and spinning equipment during development and quality control, ensuring machinery meets noise emission requirements.

• Workplace Noise Assessment
  Industrial hygienists and safety officers apply this standard to monitor noise levels in textile production facilities, helping implement noise reduction strategies and personal protective equipment policies.

• Regulatory Compliance and Certification
  Organizations responsible for certifying textile machinery rely on ISO 9902-2:2001/Amd 2:2014 to validate noise emission data for compliance with regional and international health and safety standards.

• Research and Development
  Engineers and researchers utilize the noise test methodologies described to explore innovations in quieter textile machinery designs, contributing to sustainability and improved working conditions.
