Overview
SIST EN ISO 9902-2:2002/A2:2014 is an essential European standard governing the noise testing of textile machinery, specifically focusing on spinning preparatory and spinning machinery. Developed under the International Organization for Standardization (ISO) and European Committee for Standardization (CEN), this amendment updates Part 2 of the noise test code series to ensure accurate and practical measurement of noise emissions in textile manufacturing environments. It supports compliance with EU directives related to machine safety and environmental noise control.
This standard applies rigorous procedures for measuring noise emitted by spinning preparatory machines such as carding, drawing, and roving equipment, as well as spinning machinery itself. By defining consistent testing methods, it helps manufacturers, operators, and regulatory bodies assess machine noise, contributing to safer work environments and reduced noise pollution.
Key Topics
-
Noise Test Code for Textile Machines
The standard specifies methods for conducting noise emission tests on spinning preparatory and spinning machinery, offering a standardized framework for noise measurement.
-
Applicable Equipment
Targets spinning preparatory machinery (e.g., carding machines, drawing frames, roving frames) and spinning machines used in textile production.
-
Measurement Conditions
Emphasizes the need for controlled testing conditions. It highlights that the most precise (grade 1) measurement methods are generally impractical for textile machinery, recommending alternative approaches suited to industrial settings.
-
Amendment 2 Updates
Incorporates refinements based on industry feedback to enhance measurement procedures, ensuring the standard remains relevant to current textile machinery technology and operational realities.
-
EU Directive Compliance
Aligns with essential requirements of EU Machine Directives, specifically addressing noise emission concerns under Directive 98/37/EC, supporting manufacturers in meeting legal obligations.
Applications
-
Noise Emission Assessment
Utilized by manufacturers during design validation and by testing laboratories to quantify noise levels of spinning preparatory and spinning machines.
-
Workplace Safety
Helps textile mills and factories monitor noise pollution to protect worker health, ensuring environments comply with occupational noise exposure limits.
-
Regulatory Certification
Assists in demonstrating conformity with EU and international regulations related to machine noise, facilitating market access within Europe and beyond.
-
Product Development
Guides engineering teams in designing quieter textile machinery by providing a consistent benchmark for acoustic performance.
-
Maintenance and Troubleshooting
Enables targeted noise testing to identify sources of excessive sound levels during machine servicing or troubleshooting.
