ISO 11111-5:2005/Amd 2:2016

Overview

ISO 11111-5:2005/Amd 2:2016 is an important amendment to the international standard dedicated to the safety requirements of textile machinery, specifically focusing on preparatory machinery used in weaving and knitting processes. This update, published by ISO, refines and enhances the safety guidelines originally defined in ISO 11111-5:2005 to ensure improved protection for operators and compliance with modern safety benchmarks.

The document belongs to a series under ISO 11111, which addresses safety in various types of textile machinery. Amendment 2 emphasizes updated normative references, noise reduction measures, guarding requirements, and harmonization with related ISO safety standards. The standard is developed by ISO/TC 72, the technical committee specializing in textile machinery and accessories, ensuring industry relevance and technical rigor.

Key Topics

• Safety Enhancements for Preparatory Machinery: The amendment covers specific safety precautions for preparatory machines used before weaving and knitting, including those handling beams, warp threads, rollers, and drawing-in points.
• Updated Normative References: Updates references from earlier versions of ISO 11111 and introduces ISO 23771, which sets out design measures for noise emission reduction in textile machinery.
• Guarding and Safety Devices: Specifies the requirement for physical guards or safety devices around critical pinch points such as beam-to-thread interfaces and roller mechanisms, helping to prevent operator injuries.
• Harmonization with General Safety Standards: Aligns with ISO 12100, the general standard for machinery safety principles, risk assessment, and risk reduction, replacing older cited standards.
• Noise Emission Controls: Emphasizes adherence to type C standards ISO 9902-1, ISO 9902-5, and ISO 23771 concerning noise measurement and reduction, highlighting occupational health considerations.
• Electrical Safety Updates: Revises references to IEC 60204-1 for electrical equipment safety, reflecting the newest editions applicable to machinery in the textiles sector.

Applications

This standard is critical for manufacturers, safety engineers, and maintenance personnel involved in the design, operation, and servicing of preparatory textile machinery. It ensures:

• Operator Safety: By enforcing guarding around moving parts to prevent accidents and injuries.
• Regulatory Compliance: Assists companies in meeting international safety and noise emission regulations.
• Machine Design Improvements: Facilitates integration of modern risk assessment methods and noise reduction technologies.
• Workplace Health: Promotes quieter work environments by mandating adherence to noise emission standards, protecting workers from hearing damage.
• Machinery Upgrades: Supports retrofitting and modification of existing machines to current safety standards.

Applicable in industrial weaving and knitting settings, ISO 11111-5:2005/Amd 2:2016 plays a key role in minimizing risk in preparatory stages, which are often overlooked but critical for overall process safety.
