Overview
SIST EN ISO 9902-7:2002/A1:2009 is an amendment to the international standard for textile machinery, specifically targeting dyeing and finishing machinery noise measurement. Developed by the Slovenian Institute for Standardization (SIST) and harmonized with ISO and CEN requirements, this standard sets out updated provisions for the measurement, declaration, and verification of noise emitted by various types of textile dyeing and finishing machines. It complements Part 1 of the ISO 9902 series, ensuring alignment with the latest developments and references.
The standard covers machines used in several key textile processes, including preparation, dyeing, printing, fixing, drying, finishing, calendering, and making-up or presentation. It is relevant for both engineering methods (grade 2) and survey methods (grade 3), as defined by referenced international standards.
Key Topics
- Noise Emission Measurement: Defines conditions for mounting, operating, and measuring noise levels from dyeing and finishing machinery in the textile sector.
- Standard Updates: Replaces previous references with updated versions (notably ISO 9902-1:2009), ensuring that methodologies keep pace with current international best practices.
- Test Methods: Applicable to both engineering (more precise, grade 2) and survey (practical, grade 3) test methods for noise emission assessment.
- Alignment with European Directives: Supports conformity with EU Directives 98/37/EC and 2006/42/EC on machinery safety, offering manufacturers a clear pathway to regulatory compliance.
- Scope Expansion and Reference Updates: Extends application to broader machinery process types, including coating and calendering, and updates citations to ensure use of the most recent methodologies.
Applications
SIST EN ISO 9902-7:2002/A1:2009 is highly valuable in various textile industry contexts:
- Noise Compliance and Certification: Manufacturers use this standard to verify and declare compliance with occupational noise regulations and EC Machinery Directives.
- Product Development: Engineering and R&D teams apply the measurement methods to assess and improve the acoustic performance of new machinery before market release.
- Operational Safety: Textile factories employ these procedures for regular audits, contributing to healthier working environments by controlling excessive noise exposure.
- Market Access: By adhering to this standardized testing code, machine manufacturers can demonstrate conformity to European and international requirements, simplifying export and market approval processes.
- Quality Assurance: Provides a benchmark for consistent, repeatable noise evaluation across different machinery and processing plants, supporting overall quality standards.
Related Standards
For a comprehensive conformity and testing regime, the following related standards are referenced and aligned:
- ISO 9902-1:2009: Textile machinery - Noise test code - Part 1: Common requirements (central reference for all parts of the series)
- ISO 1506: Vocabulary and classification for textile machinery
- ISO 3744, 3745, 3747: Acoustic determinations of sound power levels (engineering and survey methods)
- ISO 9614-1 and ISO 9614-2: Determination of sound power levels using sound intensity
- ISO 11201, 11202, 11203, 11204: Measurement of noise emitted by machinery at workstations and other specified positions
SIST EN ISO 9902-7:2002/A1:2009 serves as a critical tool for manufacturers, quality managers, and safety officers working to ensure accurate noise assessment, regulatory conformity, and best practices in textile machinery environments. Leveraging this standard supports operational excellence, worker safety, and access to international markets within the textile sector.
