EN IEC 61386-23:2021/A11:2021

Overview

EN IEC 61386-23:2021/A11:2021 is the European amendment to the international standard for conduit systems for cable management, focusing specifically on the particular requirements for flexible conduit systems. Issued by CLC (European Committee for Electrotechnical Standardization), this standard establishes provisions for design, classification, and environmental properties of flexible conduit systems used in electrical installations. The standard is harmonized throughout Europe, supporting regulatory compliance and facilitating safe, efficient cable management in diverse installations.

Key Topics

• Scope and Purpose: The amendment refines requirements for flexible conduit systems, addressing performance, classification, and conformity assessment to ensure effective cable protection and management.

• Halogen Content Classification: A notable update is the introduction of an optional classification based on halogen content:

  • Non declared
  • Halogen free This new criterion supports informed selection for projects emphasizing fire safety and reduced toxicity.

• Environmental Properties Clause: Conduit systems labeled as "halogen free" must comply with EN 50642:2018, a test method for content of halogens. This ensures only systems passing rigorous environmental impact criteria can be classified as halogen free.

• Annexes:

  • Annex ZA details normative references to international and European publications, ensuring alignment with the latest cable management standards.
  • Annex ZB lists special national conditions relevant in specific European countries, such as Spain and France, which may impact the application or classification of conduit systems.

Applications

EN IEC 61386-23:2021/A11:2021 applies to designers, manufacturers, and installers of flexible conduit systems for electrical cable management. It serves to:

• Support Safe Electrical Installations: By defining requirements for classification and testing, the standard helps ensure flexible conduit systems reliably protect cables from mechanical and environmental hazards.
• Aid in Product Selection: Halogen-free classification assists specifiers and project managers in choosing environmentally safer products, particularly for use in public, industrial, or high-occupancy buildings where toxic emissions must be minimized in the case of fire.
• Facilitate Regulatory Compliance: By referencing essential EU Directives and integrating special national conditions, conformity with this standard helps projects meet legal and safety mandates across Europe.
• Enable Consistency for Cross-Border Projects: Harmonization with CENELEC norms allows manufacturers and installers to use products with predictable properties and consistent classification throughout the European market.

Common applications of flexible conduit systems include:

• Commercial and residential wiring installations
• Industrial facilities with complex cable routing needs
• Retrofitting and renovation projects requiring flexible cable protection
• Environments demanding high fire and chemical resistance
