Overview

EN IEC 61591:2020/A11:2020 is a CENELEC amendment to the international standard for cooking fume extractors (range hoods) that specifies methods for measuring performance. The amendment updates test conditions, reporting conventions and links the standard to EU energy labelling (Reg. No 65/2014) and ecodesign (Reg. No 66/2014) requirements. It is intended as the harmonized reference for consistent performance measurement, declaration and conformity assessment of domestic range hoods and similar appliances.

Key topics and technical requirements

• General test conditions
  • Specified mains supply during tests: 230 V ±1% (default) or 400 V ±1% where applicable; 50 Hz ±1% supply frequency. Voltage must be recorded at the appliance connection point.
• Airflow and fluid dynamic efficiency (FDE)
  • Methods for determining volumetric air flow and calculating FDE at the Best Efficiency Point (BEP).
  • Measured pressure and power at BEP are converted to a reference air density of 1.2 kg/m³ for reporting.
• Grease filtering efficiency
  • Procedures to measure and report grease absorption (GFE) used for energy labelling.
• Lighting effectiveness
  • Test methods to determine performance of integrated lighting systems.
• Acoustical noise
  • Airborne noise measurement requirements; guidance points to statistical procedures in EN 60704-3 for declaration of noise values.
• Power measurement
  • Measurement of standby and low-power modes in accordance with IEC definitions (e.g., IEC 62301 referenced).
• Documentation and reporting
  • Clauses and annexes align test results with EU labelling and ecodesign tables to support presumption of conformity when cited in the Official Journal.

Applications and users

Who uses EN IEC 61591:2020/A11:2020:

• Manufacturers - for product development, performance claims and preparing technical documentation for market access.
• Test laboratories - to perform standardized measurements of airflow, noise, grease filtering and power consumption.
• Regulatory and compliance teams - to demonstrate conformance with EU energy labelling and ecodesign rules.
• Retailers and certification bodies - to verify declared performance for customers and compliance marks. Practical uses include verifying energy labels, optimizing aerodynamic and acoustic design, and ensuring reproducible performance data across markets.

Related standards

Normative and informative references include:

• IEC 60704-2-13 / EN 60704-2-13 (airborne acoustical noise for range hoods)
• IEC 62301 (measurement of standby power)
• ISO 5167 parts 1–4 (flow measurement by differential pressure devices)
• ISO 80000-1 (quantities and units)
• IEC 60584-1 (thermocouples)
