ISO 11111-4:2005/Amd 2:2016

Overview

ISO 11111-4:2005/Amd 2:2016 is an important international standard published by the International Organization for Standardization (ISO) that addresses safety requirements for textile machinery, specifically focusing on yarn processing, cordage, and rope manufacturing machinery. As an amendment to the original 2005 edition, this 2016 update reflects the latest safety protocols and technical revisions necessary to protect operators and machinery in the textile industry.

Developed under the guidance of ISO Technical Committee ISO/TC 72, Subcommittee SC 8, this standard integrates practical safety measures designed to mitigate risks associated with complex textile manufacturing equipment. It aligns with other key safety standards such as ISO 12100 for risk assessment and reduction and refers to noise emission standards to ensure comprehensive machine safety.

Key Topics

• Safety Requirements for Yarn Processing Machinery
  The standard defines specific safety criteria for machines used in spinning, twisting, and other yarn processing operations, addressing mechanical hazards, guarding, and emergency stopping mechanisms.

• Cordage and Rope Manufacturing Safety
  It provides safety mandates for the design and operation of machinery involved in producing cords and ropes, ensuring safe interaction between operators and equipment to prevent accidents.

• Updates and Revisions in Amendment 2
  The amendment updates references to more recent ISO standards for safety such as ISO 12100 (general machinery safety principles) and ISO 14119 (interlocking devices), ensuring the latest compliance measures. It incorporates enhanced normative references around noise reduction and safety device testing, reinforcing safer working environments.

• Emergency Stop and Protective Devices
  Specifies the requirement for pushbutton emergency stop devices to be accessible on each end section of the machinery, reinforcing quick response capability during emergencies. It also revises principles concerning pressure-sensitive protective devices to enhance machine safeguarding.

• Noise Emission Standards Integration
  ISO 11111-4:2005/Amd 2:2016 highlights the complementarity of noise emission standards such as ISO 9902-1 and ISO 23771, providing guidance for noise measurement and reduction in textile machinery.

Applications

• Textile Manufacturing Plants
  Factories operating yarn processing, cordage, and rope manufacturing machinery can implement this standard to enhance workplace safety, comply with legal requirements, and reduce the risk of machinery-related incidents.

• Machine Designers and Manufacturers
  Provides essential criteria and guidelines for designing safer textile machinery, helping manufacturers incorporate state-of-the-art safety features and meet international compliance standards.

• Safety Auditors and Compliance Inspectors
  Useful for professionals performing safety assessments and ensuring that textile production equipment adheres to updated safety protocols as mandated by international regulations.

• Risk Assessment and Engineering Controls
  ISO 11111-4 amendment contributes to improved risk identification and mitigation strategies, supporting the design and installation of engineering controls in textile machinery.
