Overview
EN 12237:2003 - "Ventilation for buildings - Ductwork - Strength and leakage of circular sheet metal ducts" (CEN) specifies requirements and test methods to verify the mechanical strength and air leakage performance of circular sheet‑metal ductwork used in building ventilation and air‑conditioning systems. The standard is intended primarily for in‑situ (on‑site) measurements, with provisions for laboratory testing, and its air‑leakage methods are also applicable to rectangular ductwork.
Key topics and technical requirements
- Scope and purpose
- Establishes acceptance criteria to verify fitness for intended service as installed ductwork.
- Applies to ductwork assemblies and product series.
- Airtightness classes
- Defines air‑tightness classes (A–D) with associated static pressure limits and permitted leakage limits; numerical limits and curves are given in the standard (see Table 2).
- Leakage measurement
- Uses the leakage factor f = qv / Aj (leakage flow per unit duct surface area).
- Leakage must be below the class limit for test pressures up to the design operating pressure.
- Measured leakage is corrected to standard conditions (standard temp and barometric pressure) - correction method provided.
- Strength requirements
- Ductwork must withstand specified static pressure limits without permanent deformation or sudden changes in leakage/pressure.
- Deformation reportable when cross‑sectional area reduces by ≥10%.
- Test sampling and procedure
- In‑situ sample should represent the installed system; test section surface area ≥10% of total (preferably ≥10 m²).
- For generic product testing, minimum test surface area is 10 m² and straight ducts ≥2.5 m included.
- Test pressures (positive and negative) are applied and held within ±5% for at least 5 minutes for stable readings.
- Test rig & calibration
- Test equipment must be inspected and carry a calibration certificate (calibrated within one year).
- Reporting
- The standard specifies detailed test report contents (test conditions, equipment, Aj, total joint length, corrected leakage, achieved airtightness class, observed deformations, etc.).
- Annex A
- Provides a recommended procedure when measured leakage exceeds permitted rates (stepwise extension of test area).
Practical applications
- Ensures compliance of ventilation ductwork with performance and safety expectations.
- Used during commissioning, acceptance testing, and periodic verification of HVAC installations.
- Useful for design validation, product development testing, and quality control in manufacturing.
