SIST EN ISO 9902-7:2002/A2:2014 PDF

Overview

SIST EN ISO 9902-7:2002/A2:2014 is an important international standard focused on the noise testing of textile machinery, specifically dyeing and finishing machinery. Developed through a collaboration between ISO Technical Committee 72 (Textile machinery and related equipment) and CEN/TC 214 (Textile machinery and accessories), this standard sets out noise measurement codes and procedures to help manufacturers and users assess the noise emissions of textile finishing machines. The amendment (A2:2014) updates the original ISO 9902-7:2001 to reflect improved requirements and align with European regulatory frameworks.

This standard supports compliance with EU directives related to machinery safety and environmental noise, offering manufacturers practical guidance on noise emission testing in dyeing and finishing processes. It also provides a benchmark for noise control, helping reduce occupational noise exposure and environmental noise pollution in textile manufacturing facilities.

Key Topics

• Scope of Application: Applies specifically to dyeing and finishing textile machinery, covering the noise emitted during machine operation.
• Noise Measurement Methods: Defines the test code procedures, emphasizing standardized operating and environmental conditions to ensure comparability of noise data.
• Testing Environment Requirements: Details requirements for measurement locations and machine setup, recognizing that high-grade noise measurement methods may be difficult to implement in typical textile manufacturing environments.
• Reference to EU Directives: Offers conformance guidance with EU Directive 98/37/EC (Machinery Directive) and related safety and noise emission legislation.
• Amendment Details: The 2014 amendment clarifies testing conditions and reinforces the practical measurement methods relevant for the textile industry, addressing challenges such as operational noise variability.
• Documentation and Reporting: Stipulates the presentation of test results for transparency and comparability.

Applications

• Manufacturers of Dyeing and Finishing Equipment: Enable product design improvements to lower noise emissions and demonstrate compliance with international and regional regulations.
• Textile Factories and Industrial Laundries: Use the standard to assess machine noise levels, helping protect workers from occupational noise hazards and maintain a safer work environment.
• Regulatory Bodies and Compliance Auditors: Utilize the standard as a reference for certification or regulatory inspections related to noise emissions in textile machinery.
• Research and Development: Provides baseline testing methodologies for innovation and noise reduction strategy development in textile machinery.
• Environmental Health and Safety Programs: Supports initiatives aimed at reducing environmental noise pollution within industrial zones using textile machinery.

Related Standards

• ISO 9902 (Noise Test Codes) Series: EN ISO 9902-7 is part of the broader 9902 series addressing noise test codes for various types of textile machinery.
• EU Machinery Directive 98/37/EC: The standard aligns with key essential requirements focused on machinery safety, including noise emissions.
• ISO/IEC Directives Part 2: Governs the drafting of international standards, ensuring consistency in terminology and structure.
• Other Textile Machinery Safety Standards: Such as EN ISO 12100 for general machine safety principles.

By following SIST EN ISO 9902-7:2002/A2:2014, stakeholders in the textile industry can effectively manage noise emissions, ensuring safer and more environmentally responsible dyeing and finishing operations. This standard is indispensable for compliance, quality assurance, and sustainable textile machinery manufacturing and usage.
