Overview
SIST EN ISO 9902-5:2002/A2:2014 is an international standard focused on the measurement, declaration, and verification of noise emissions from weaving and knitting preparatory machinery. Developed by the Slovenian Institute for Standardization (SIST) in alignment with ISO and CEN requirements, this standard is an integral supplement to Part 1 of the ISO 9902 series, concentrating on textile machinery noise test codes. This document specifically addresses the engineering and survey methods required for reliable measurement of sound emissions from warping, beaming, and sizing machines, ensuring compliance with relevant regulatory and safety obligations in the textile industry.
Key Topics
- Scope and Applicability: Specifies mounting, operation, and measurement conditions, ensuring accurate assessment of noise emissions for weaving and knitting preparatory machines-mainly warping, beaming, and sizing equipment as covered in ISO 2544.
- Testing Methodology: Supports engineering methods (grade 2) and survey methods (grade 3) as defined in referenced standards. Grade 1 methods are typically not feasible for textile machinery due to stringent measurement requirements.
- Noise Measurement Conditions: Outlines standardized procedures for machine installation, operation during testing, and locations for sound level measurements to maintain consistency and repeatability.
- Regulatory Alignment: Developed under the Vienna Agreement for parallel ISO and CEN processing, facilitating conformance with EU Directives, particularly concerning essential health and safety requirements related to machine noise.
- Declaration and Verification: Details requirements for declaring noise emission values and procedures for verifying compliance, supporting both manufacturers and regulatory bodies.
Applications
SIST EN ISO 9902-5:2002/A2:2014 is critical for stakeholders in the textile machinery sector, including manufacturers, plant operators, safety auditors, and regulatory agencies. Key applications include:
- Machinery Design and Manufacturing: Supports integration of noise control measures by providing consistent reference criteria for assessing acoustic emissions during product development.
- Workplace Safety and Compliance: Enables manufacturers and operators to verify that existing or new textile machinery complies with occupational hearing safety regulations, reducing risk to workers exposed to high noise levels.
- Product Certification and Market Access: Conformance with this standard can demonstrate fulfillment of essential EU and international requirements, streamlining market approvals and acceptance across European countries.
- Maintenance and Retrofits: Offers benchmarks for monitoring acoustic performance over a machine’s operational life, assisting in decision-making regarding retrofits or upgrades to maintain compliance.
