Overview

EN 13180:2001 - published by CEN - defines dimensions and mechanical requirements for flexible ducts used in ventilation and air conditioning installations in buildings for human occupancy. The standard sets out required test methods and acceptance criteria for flexible ductwork so manufacturers, test laboratories, specifiers and installers can verify nominal diameter, length, mechanical resistance and air tightness. Note: acoustic, thermal, reaction-to-fire and pressure-loss properties are explicitly excluded.

Key topics and technical requirements

• Scope: Requirements and test methods for flexible ducts used in building ventilation and air‑conditioning systems.
• Parameters covered:
  • Dimensions and tolerances (nominal diameters and permitted deviations for circular ducts; manufacturer-specified values for non-circular ducts).
  • Mechanical resistance, including crushing strength (compressed and uncompressed), bending capability, sag and pressure resistance.
  • Air leakage / airtightness expressed as an air leakage factor; three air‑tightness classes (A, B, C) with class limits defined by a formula dependent on test pressure (ps).
• Test methods & samples:
  • Three test elements (compressed end section, initial sample, uncompressed mid‑section) with specified tests for each element.
  • Tests include measurement of nominal diameter, decompressed length, sag (angle), manual bending cycles, positive and negative pressure endurance, crushing tests and airtightness measurement.
• Performance limits:
  • Deformation limits during bending and pressure tests (duct height change not to exceed ±20%; recovery within 5% after a 5‑minute recovery period).
  • Pressure test requirement: ducts must withstand 2.5× manufacturer’s quoted positive and negative rated pressures when tested.
• Marking: Products must be labelled with at least nominal diameter and nominal length.

Applications and who uses it

EN 13180 is intended for:

• Duct manufacturers - for product design, quality control and factory testing.
• HVAC designers and specifiers - to select flexible ducts that meet dimensional and mechanical requirements.
• Testing laboratories and certification bodies - to perform standardized mechanical and airtightness tests.
• Installers and building engineers - to verify delivered products meet specified nominal dimensions and mechanical performance for safe, durable ductwork in ventilation systems.

Related standards

• EN 13180 is part of the CEN/TC 156 series on ductwork for buildings.
• Referenced standard: EN 1506 (sheet metal circular ducts - dimensions), which complements EN 13180 for rigid duct components.
