Overview
EN ISO 11111-4:2005 - "Textile machinery - Safety requirements - Part 4: Yarn processing, cordage and rope manufacturing machinery (ISO 11111-4:2005)" is a CEN-adopted international standard that defines significant hazards and associated safety requirements for machinery used in yarn processing, cordage and rope production. It is intended to be used together with ISO 11111-1 (Common requirements) and forms part of the ISO 11111 series covering textile machinery safety. The standard applies to equipment for doubling, twisting, texturing, reeling, winding, ball winding, cordage and rope manufacture, and braiding.
Key topics
- Scope and structure: Clauses cover scope, normative references, terms, list of significant hazards, specific safety requirements and measures, verification of safety requirements, and user information.
- Hazard identification: Focuses on significant hazards specific to yarn and rope machinery in conjunction with the common hazards addressed in ISO 11111-1.
- Machine-specific requirements: Addresses safety for doubling, twisting and texturing machines; reeling and winding equipment; ball winding; cordage, stranding, laying (closing) and combined rope-making machines; and braiding machines.
- Safeguarding measures: Emphasizes guards, interlocking devices and safety-related control systems - referencing related standards for design and validation (e.g., ISO 14119 for interlocks, ISO 13849-1 for safety-related control systems).
- Physical safety parameters: Incorporates principles from standards on safety distances and minimum gaps to prevent reaching-in and crushing (ISO 13852, ISO 13854).
- Verification and documentation: Includes requirements for verification of safety measures and mandatory information for safe machine use (operation, maintenance and inspection guidance).
- Noise considerations: References ISO 9902 series for noise test code applicable to yarn processing and rope machinery.
Applications and users
This standard is practical for:
- Machine designers and manufacturers - to design compliant yarn processing and rope-making equipment with appropriate guarding, control systems and safety verification.
- System integrators and plant engineers - to specify safe machinery layouts, guarding strategies and control integration.
- Safety managers and compliance officers - to evaluate machine risk, verify conformity and prepare user documentation.
- Inspectors and certification bodies - to assess conformity with CEN requirements and the Machinery Directive (see Annex ZB regarding Directive 98/37/EC).
